text: 'We present a novel approach to differential cost analysis that, given a program
revision, attempts to statically bound the difference in resource usage, or cost,
between the two program versions. Differential cost analysis is particularly interesting
because of the many compelling applications for it, such as detecting resource-use
regressions at code-review time or proving the absence of certain side-channel
vulnerabilities. One prior approach to differential cost analysis is to apply
relational reasoning that conceptually constructs a product program on which one
can over-approximate the difference in costs between the two program versions.
However, a significant challenge in any relational approach is effectively aligning
the program versions to get precise results. In this paper, our key insight is
that we can avoid the need for and the limitations of program alignment if, instead,
we bound the difference of two cost-bound summaries rather than directly bounding
the concrete cost difference. In particular, our method computes a threshold value
for the maximal difference in cost between two program versions simultaneously
using two kinds of cost-bound summaries---a potential function that evaluates
to an upper bound for the cost incurred in the first program and an anti-potential
function that evaluates to a lower bound for the cost incurred in the second.
Our method has a number of desirable properties: it can be fully automated, it
allows optimizing the threshold value on relative cost, it is suitable for programs
that are not syntactically similar, and it supports non-determinism. We have evaluated
an implementation of our approach on a number of program pairs collected from
the literature, and we find that our method computes tight threshold values on
relative cost in most examples.'

text: Structural balance theory is an established framework for studying social
relationships of friendship and enmity. These relationships are modeled by a signed
network whose energy potential measures the level of imbalance, while stochastic
dynamics drives the network toward a state of minimum energy that captures social
balance. It is known that this energy landscape has local minima that can trap
socially aware dynamics, preventing it from reaching balance. Here we first study
the robustness and attractor properties of these local minima. We show that a
stochastic process can reach them from an abundance of initial states and that
some local minima cannot be escaped by mild perturbations of the network. Motivated
by these anomalies, we introduce best-edge dynamics (BED), a new plausible stochastic
process. We prove that BED always reaches balance and that it does so fast in
various interesting settings.

text: 'In repeated interactions, players can use strategies that respond to the
outcome of previous rounds. Much of the existing literature on direct reciprocity
assumes that all competing individuals use the same strategy space. Here, we study
both learning and evolutionary dynamics of players that differ in the strategy
space they explore. We focus on the infinitely repeated donation game and compare
three natural strategy spaces: memory-1 strategies, which consider the last moves
of both players, reactive strategies, which respond to the last move of the co-player,
and unconditional strategies. These three strategy spaces differ in the memory
capacity that is needed. We compute the long term average payoff that is achieved
in a pairwise learning process. We find that smaller strategy spaces can dominate
larger ones. For weak selection, unconditional players dominate both reactive
and memory-1 players. For intermediate selection, reactive players dominate memory-1
players. Only for strong selection and low cost-to-benefit ratio, memory-1 players
dominate the others. We observe that the supergame between strategy spaces can
be a social dilemma: maximum payoff is achieved if both players explore a larger
strategy space, but smaller strategy spaces dominate.'

text: 'Partially observable Markov decision processes (POMDPs) are standard models
for dynamic systems with probabilistic and nondeterministic behaviour in uncertain
environments. We prove that in POMDPs with long-run average objective, the decision
maker has approximately optimal strategies with finite memory. This implies notably
that approximating the long-run value is recursively enumerable, as well as a
weak continuity property of the value with respect to the transition function. '

text: We present PET, a specialized and highly optimized framework for partial exploration
on probabilistic systems. Over the last decade, several significant advances in
the analysis of Markov decision processes employed partial exploration. In a nutshell,
this idea allows to focus computation on specific parts of the system, guided
by heuristics, while maintaining correctness. In particular, only relevant parts
of the system are constructed on demand, which in turn potentially allows to omit
constructing large parts of the system. Depending on the model, this leads to
dramatic speed-ups, in extreme cases even up to an arbitrary factor. PET unifies
several previous implementations and provides a flexible framework to easily implement
partial exploration for many further problems. Our experimental evaluation shows
significant improvements compared to the previous implementations while vastly
reducing the overhead required to add support for additional properties.
acknowledgement: We thank Pranav Ashok and Maximilian Weininger for their contributions
to spiritual predecessors of PET as well as motivating the initial development of
this tool.

text: Fixed-horizon planning considers a weighted graph and asks to construct a
path that maximizes the sum of weights for a given time horizon T. However, in
many scenarios, the time horizon is not fixed, but the stopping time is chosen
according to some distribution such that the expected stopping time is T. If the
stopping-time distribution is not known, then to ensure robustness, the distribution
is chosen by an adversary as the worst-case scenario. A stationary plan for every
vertex always chooses the same outgoing edge. For fixed horizon or fixed stopping-time
distribution, stationary plans are not sufficient for optimality. Quite surprisingly
we show that when an adversary chooses the stopping-time distribution with expected
stopping-time T, then stationary plans are sufficient. While computing optimal
stationary plans for fixed horizon is NP-complete, we show that computing optimal
stationary plans under adversarial stopping-time distribution can be achieved
in polynomial time.

text: "We consider the problem of approximating the reachability probabilities in
Markov decision processes (MDP) with uncountable (continuous) state and action
spaces. While there are algorithms that, for special classes of such MDP, provide
a sequence of approximations converging to the true value in the limit, our aim
is to obtain an algorithm with guarantees on the precision of the approximation.\r\nAs
this problem is undecidable in general, assumptions on the MDP are necessary.
Our main contribution is to identify sufficient assumptions that are as weak as
possible, thus approaching the \"boundary\" of which systems can be correctly
and reliably analyzed. To this end, we also argue why each of our assumptions
is necessary for algorithms based on processing finitely many observations.\r\nWe
present two solution variants. The first one provides converging lower bounds
under weaker assumptions than typical ones from previous works concerned with
guarantees. The second one then utilizes stronger assumptions to additionally
provide converging upper bounds. Altogether, we obtain an anytime algorithm, i.e.
yielding a sequence of approximants with known and iteratively improving precision,
converging to the true value in the limit. Besides, due to the generality of our
assumptions, our algorithms are very general templates, readily allowing for various
heuristics from literature in contrast to, e.g., a specific discretization algorithm.
Our theoretical contribution thus paves the way for future practical improvements
without sacrificing correctness guarantees."

text: "We consider the quantitative problem of obtaining lower-bounds on the probability
of termination of a given non-deterministic probabilistic program. Specifically,
given a non-termination threshold p∈[0,1], we aim for certificates proving that
the program terminates with probability at least 1−p. The basic idea of our approach
is to find a terminating stochastic invariant, i.e. a subset SI of program states
such that (i) the probability of the program ever leaving SI is no more than p,
and (ii) almost-surely, the program either leaves SI or terminates.\r\n\r\nWhile
stochastic invariants are already well-known, we provide the first proof that
the idea above is not only sound, but also complete for quantitative termination
analysis. We then introduce a novel sound and complete characterization of stochastic
invariants that enables template-based approaches for easy synthesis of quantitative
termination certificates, especially in affine or polynomial forms. Finally, by
combining this idea with the existing martingale-based methods that are relatively
complete for qualitative termination analysis, we obtain the first automated,
sound, and relatively complete algorithm for quantitative termination analysis.
Notably, our completeness guarantees for quantitative termination analysis are
as strong as the best-known methods for the qualitative variant.\r\n\r\nOur prototype
implementation demonstrates the effectiveness of our approach on various probabilistic
programs. We also demonstrate that our algorithm certifies lower bounds on termination
probability for probabilistic programs that are beyond the reach of previous methods."

text: "We consider the problem of formally verifying almost-sure (a.s.) asymptotic
stability in discrete-time nonlinear stochastic control systems. While verifying
stability in deterministic control systems is extensively studied in the literature,
verifying stability in stochastic control systems is an open problem. The few
existing works on this topic either consider only specialized forms of stochasticity
or make restrictive assumptions on the system, rendering them inapplicable to
learning algorithms with neural network policies. \r\n In this work, we present
an approach for general nonlinear stochastic control problems with two novel aspects:
(a) instead of classical stochastic extensions of Lyapunov functions, we use ranking
supermartingales (RSMs) to certify a.s. asymptotic stability, and (b) we present
a method for learning neural network RSMs. \r\n We prove that our approach guarantees
a.s. asymptotic stability of the system and\r\n provides the first method to obtain
bounds on the stabilization time, which stochastic Lyapunov functions do not.\r\n
Finally, we validate our approach experimentally on a set of nonlinear stochastic
reinforcement learning environments with neural network policies."

text: "In this work, we address the problem of learning provably stable neural\r\nnetwork
policies for stochastic control systems. While recent work has\r\ndemonstrated
the feasibility of certifying given policies using martingale\r\ntheory, the problem
of how to learn such policies is little explored. Here, we\r\nstudy the effectiveness
of jointly learning a policy together with a martingale\r\ncertificate that proves
its stability using a single learning algorithm. We\r\nobserve that the joint
optimization problem becomes easily stuck in local\r\nminima when starting from
a randomly initialized policy. Our results suggest\r\nthat some form of pre-training
of the policy is required for the joint\r\noptimization to repair and verify the
policy successfully."

text: We study the problem of learning controllers for discrete-time non-linear
stochastic dynamical systems with formal reach-avoid guarantees. This work presents
the first method for providing formal reach-avoid guarantees, which combine and
generalize stability and safety guarantees, with a tolerable probability threshold
$p\in[0,1]$ over the infinite time horizon. Our method leverages advances in machine
learning literature and it represents formal certificates as neural networks.
In particular, we learn a certificate in the form of a reach-avoid supermartingale
(RASM), a novel notion that we introduce in this work. Our RASMs provide reachability
and avoidance guarantees by imposing constraints on what can be viewed as a stochastic
extension of level sets of Lyapunov functions for deterministic systems. Our approach
solves several important problems -- it can be used to learn a control policy
from scratch, to verify a reach-avoid specification for a fixed control policy,
or to fine-tune a pre-trained policy if it does not satisfy the reach-avoid specification.
We validate our approach on $3$ stochastic non-linear reinforcement learning tasks.

text: "A deterministic finite automaton (DFA) \U0001D49C is composite if its language
L(\U0001D49C) can be decomposed into an intersection ⋂_{i = 1}^k L(\U0001D49C_i)
of languages of smaller DFAs. Otherwise, \U0001D49C is prime. This notion of primality
was introduced by Kupferman and Mosheiff in 2013, and while they proved that we
can decide whether a DFA is composite, the precise complexity of this problem
is still open, with a doubly-exponential gap between the upper and lower bounds.
In this work, we focus on permutation DFAs, i.e., those for which the transition
monoid is a group. We provide an NP algorithm to decide whether a permutation
DFA is composite, and show that the difficulty of this problem comes from the
number of non-accepting states of the instance: we give a fixed-parameter tractable
algorithm with the number of rejecting states as the parameter. Moreover, we investigate
the class of commutative permutation DFAs. Their structural properties allow us
to decide compositionality in NL, and even in LOGSPACE if the alphabet size is
fixed. Despite this low complexity, we show that complex behaviors still arise
in this class: we provide a family of composite DFAs each requiring polynomially
many factors with respect to its size. We also consider the variant of the problem
that asks whether a DFA is k-factor composite, that is, decomposable into k smaller
DFAs, for some given integer k ∈ ℕ. We show that, for commutative permutation
DFAs, restricting the number of factors makes the decision computationally harder,
and yields a problem with tight bounds: it is NP-complete. Finally, we show that
in general, this problem is in PSPACE, and it is in LOGSPACE for DFAs with a singleton
alphabet."

text: 'Graphs and games on graphs are fundamental models for the analysis of reactive
systems, in particular, for model-checking and the synthesis of reactive systems.
The class of ω-regular languages provides a robust specification formalism for
the desired properties of reactive systems. In the classical infinitary formulation
of the liveness part of an ω-regular specification, a "good" event must happen
eventually without any bound between the good events. A stronger notion of liveness
is bounded liveness, which requires that good events happen within d transitions.
Given a graph or a game graph with n vertices, m edges, and a bounded liveness
objective, the previous best-known algorithmic bounds are as follows: (i) O(dm)
for graphs, which in the worst-case is O(n³); and (ii) O(n² d²) for games on graphs.
Our main contributions improve these long-standing algorithmic bounds. For graphs
we present: (i) a randomized algorithm with one-sided error with running time
O(n^{2.5} log n) for the bounded liveness objectives; and (ii) a deterministic
linear-time algorithm for the complement of bounded liveness objectives. For games
on graphs, we present an O(n² d) time algorithm for the bounded liveness objectives.'

text: We study the expressiveness and succinctness of good-for-games pushdown automata
(GFG-PDA) over finite words, that is, pushdown automata whose nondeterminism can
be resolved based on the run constructed so far, but independently of the remainder
of the input word. We prove that GFG-PDA recognise more languages than deterministic
PDA (DPDA) but not all context-free languages (CFL). This class is orthogonal
to unambiguous CFL. We further show that GFG-PDA can be exponentially more succinct
than DPDA, while PDA can be double-exponentially more succinct than GFG-PDA. We
also study GFGness in visibly pushdown automata (VPA), which enjoy better closure
properties than PDA, and for which we show GFGness to be ExpTime-complete. GFG-VPA
can be exponentially more succinct than deterministic VPA, while VPA can be exponentially
more succinct than GFG-VPA. Both of these lower bounds are tight. Finally, we
study the complexity of resolving nondeterminism in GFG-PDA. Every GFG-PDA has
a positional resolver, a function that resolves nondeterminism and that is only
dependant on the current configuration. Pushdown transducers are sufficient to
implement the resolvers of GFG-VPA, but not those of GFG-PDA. GFG-PDA with finite-state
resolvers are determinisable.

text: In the Intersection Non-emptiness problem, we are given a list of finite automata
A_1, A_2,… , A_m over a common alphabet Σ as input, and the goal is to determine
whether some string w ∈ Σ^* lies in the intersection of the languages accepted
by the automata in the list. We analyze the complexity of the Intersection Non-emptiness
problem under the promise that all input automata accept a language in some level
of the dot-depth hierarchy, or some level of the Straubing-Thérien hierarchy.
Automata accepting languages from the lowest levels of these hierarchies arise
naturally in the context of model checking. We identify a dichotomy in the dot-depth
hierarchy by showing that the problem is already NP-complete when all input automata
accept languages of the levels B_0 or B_{1/2} and already PSPACE-hard when all
automata accept a language from the level B_1. Conversely, we identify a tetrachotomy
in the Straubing-Thérien hierarchy. More precisely, we show that the problem is
in AC^0 when restricted to level L_0; complete for L or NL, depending on the input
representation, when restricted to languages in the level L_{1/2}; NP-complete
when the input is given as DFAs accepting a language in L_1 or L_{3/2}; and finally,
PSPACE-complete when the input automata accept languages in level L_2 or higher.
Moreover, we show that the proof technique used to show containment in NP for
DFAs accepting languages in L_1 or L_{3/2} does not generalize to the context
of NFAs. To prove this, we identify a family of languages that provide an exponential
separation between the state complexity of general NFAs and that of partially
ordered NFAs. To the best of our knowledge, this is the first superpolynomial
separation between these two models of computation.

text: "Product graphs arise naturally in formal verification and program analysis.
For example, the analysis of two concurrent threads requires the product of two
component control-flow graphs, and for language inclusion of deterministic automata
the product of two automata is constructed. In many cases, the component graphs
have constant treewidth, e.g., when the input contains control-flow graphs of
programs. We consider the algorithmic analysis of products of two constant-treewidth
graphs with respect to three classic specification languages, namely, (a) algebraic
properties, (b) mean-payoff properties, and (c) initial credit for energy properties.\r\nOur
main contributions are as follows. Consider a graph G that is the product of two
constant-treewidth graphs of size n each. First, given an idempotent semiring,
we present an algorithm that computes the semiring transitive closure of G in
time Õ(n⁴). Since the output has size Θ(n⁴), our algorithm is optimal (up to
polylog factors). Second, given a mean-payoff objective, we present an O(n³)-time
algorithm for deciding whether the value of a starting state is non-negative,
improving the previously known O(n⁴) bound. Third, given an initial credit for
energy objective, we present an O(n⁵)-time algorithm for computing the minimum
initial credit for all nodes of G, improving the previously known O(n⁸) bound.
At the heart of our approach lies an algorithm for the efficient construction
of strongly-balanced tree decompositions of constant-treewidth graphs. Given a
constant-treewidth graph G' of n nodes and a positive integer λ, our algorithm
constructs a binary tree decomposition of G' of width O(λ) with the property that
the size of each subtree decreases geometrically with rate (1/2 + 2^{-λ})."

text: 'In a two-player zero-sum graph game the players move a token throughout a
graph to produce an infinite path, which determines the winner or payoff of the
game. Traditionally, the players alternate turns in moving the token. In bidding
games, however, the players have budgets, and in each turn, we hold an “auction”
(bidding) to determine which player moves the token: both players simultaneously
submit bids and the higher bidder moves the token. The bidding mechanisms differ
in their payment schemes. Bidding games were largely studied with variants of
first-price bidding in which only the higher bidder pays his bid. We focus on
all-pay bidding, where both players pay their bids. Finite-duration all-pay bidding
games were studied and shown to be technically more challenging than their first-price
counterparts. We study for the first time, infinite-duration all-pay bidding games.
Our most interesting results are for mean-payoff objectives: we portray a complete
picture for games played on strongly-connected graphs. We study both pure (deterministic)
and mixed (probabilistic) strategies and completely characterize the optimal and
almost-sure (with probability 1) payoffs the players can respectively guarantee.
We show that mean-payoff games under all-pay bidding exhibit the intriguing mathematical
properties of their first-price counterparts; namely, an equivalence with random-turn
games in which in each turn, the player who moves is selected according to a (biased)
coin toss. The equivalences for all-pay bidding are more intricate and unexpected
than for first-price bidding.'

text: 'We study the two-player zero-sum extension of the partially observable stochastic
shortest-path problem where one agent has only partial information about the environment.
We formulate this problem as a partially observable stochastic game (POSG): given
a set of target states and negative rewards for each transition, the player with
imperfect information maximizes the expected undiscounted total reward until a
target state is reached. The second player with the perfect information aims for
the opposite. We base our formalism on POSGs with one-sided observability (OS-POSGs)
and give the following contributions: (1) we introduce a novel heuristic search
value iteration algorithm that iteratively solves depth-limited variants of the
game, (2) we derive the bound on the depth guaranteeing an arbitrary precision,
(3) we propose a novel upper-bound estimation that allows early terminations,
and (4) we experimentally evaluate the algorithm on a pursuit-evasion game.'

text: ' matching is compatible to two or more labeled point sets of size n with
labels {1,…,n} if its straight-line drawing on each of these point sets is
crossing-free. We study the maximum number of edges in a matching compatible to
two or more labeled point sets in general position in the plane. We show that
for any two labeled convex sets of n points there exists a compatible matching
with ⌊2n−−√⌋ edges. More generally, for any ℓ labeled point sets we construct
compatible matchings of size Ω(n1/ℓ) . As a corresponding upper bound, we use
probabilistic arguments to show that for any ℓ given sets of n points there
exists a labeling of each set such that the largest compatible matching has O(n2/(ℓ+1)) edges.
Finally, we show that Θ(logn) copies of any set of n points are necessary and
sufficient for the existence of a labeling such that any compatible matching consists
only of a single edge.'

text: Optimal decision making requires individuals to know their available options
and to anticipate correctly what consequences these options have. In many social
interactions, however, we refrain from gathering all relevant information, even
if this information would help us make better decisions and is costless to obtain.
This chapter examines several examples of “deliberate ignorance.” Two simple models
are proposed to illustrate how ignorance can evolve among self-interested and
payoff - maximizing individuals, and open problems are highlighted that lie ahead
for future research to explore.

text: "Several problems in planning and reactive synthesis can be reduced to the
analysis of two-player quantitative graph games. Optimization is one form of analysis.
We argue that in many cases it may be better to replace the optimization problem
with the satisficing problem, where instead of searching for optimal solutions,
the goal is to search for solutions that adhere to a given threshold bound.\r\nThis
work defines and investigates the satisficing problem on a two-player graph game
with the discounted-sum cost model. We show that while the satisficing problem
can be solved using numerical methods just like the optimization problem, this
approach does not render compelling benefits over optimization. When the discount
factor is, however, an integer, we present another approach to satisficing, which
is purely based on automata methods. We show that this approach is algorithmically
more performant – both theoretically and empirically – and demonstrates the broader
applicability of satisficing over optimization."

text: Bayesian neural networks (BNNs) place distributions over the weights of a
neural network to model uncertainty in the data and the network's prediction.
We consider the problem of verifying safety when running a Bayesian neural network
policy in a feedback loop with infinite time horizon systems. Compared to the
existing sampling-based approaches, which are inapplicable to the infinite time
horizon setting, we train a separate deterministic neural network that serves
as an infinite time horizon safety certificate. In particular, we show that the
certificate network guarantees the safety of the system over a subset of the BNN
weight posterior's support. Our method first computes a safe weight set and then
alters the BNN's weight posterior to reject samples outside this set. Moreover,
we show how to extend our approach to a safe-exploration reinforcement learning
setting, in order to avoid unsafe trajectories during the training of the policy.
We evaluate our approach on a series of reinforcement learning benchmarks, including
non-Lyapunovian safety specifications.

text: We study optimal election sequences for repeatedly selecting a (very) small
group of leaders among a set of participants (players) with publicly known unique
ids. In every time slot, every player has to select exactly one player that it
considers to be the current leader, oblivious to the selection of the other players,
but with the overarching goal of maximizing a given parameterized global (“social”)
payoff function in the limit. We consider a quite generic model, where the local
payoff achieved by a given player depends, weighted by some arbitrary but fixed
real parameter, on the number of different leaders chosen in a round, the number
of players that choose the given player as the leader, and whether the chosen
leader has changed w.r.t. the previous round or not. The social payoff can be
the maximum, average or minimum local payoff of the players. Possible applications
include quite diverse examples such as rotating coordinator-based distributed
algorithms and long-haul formation flying of social birds. Depending on the weights
and the particular social payoff, optimal sequences can be very different, from
simple round-robin where all players chose the same leader alternatingly every
time slot to very exotic patterns, where a small group of leaders (at most 2)
is elected in every time slot. Moreover, we study the question if and when a single
player would not benefit w.r.t. its local payoff when deviating from the given
optimal sequence, i.e., when our optimal sequences are Nash equilibria in the
restricted strategy space of oblivious strategies. As this is the case for many
parameterizations of our model, our results reveal that no punishment is needed
to make it rational for the players to optimize the social payoff.

text: 'A game of rock-paper-scissors is an interesting example of an interaction
where none of the pure strategies strictly dominates all others, leading to a
cyclic pattern. In this work, we consider an unstable version of rock-paper-scissors
dynamics and allow individuals to make behavioural mistakes during the strategy
execution. We show that such an assumption can break a cyclic relationship leading
to a stable equilibrium emerging with only one strategy surviving. We consider
two cases: completely random mistakes when individuals have no bias towards any
strategy and a general form of mistakes. Then, we determine conditions for a strategy
to dominate all other strategies. However, given that individuals who adopt a
dominating strategy are still prone to behavioural mistakes in the observed behaviour,
we may still observe extinct strategies. That is, behavioural mistakes in strategy
execution stabilise evolutionary dynamics leading to an evolutionary stable and,
potentially, mixed co-existence equilibrium.'

text: 'Selection and random drift determine the probability that novel mutations
fixate in a population. Population structure is known to affect the dynamics of
the evolutionary process. Amplifiers of selection are population structures that
increase the fixation probability of beneficial mutants compared to well-mixed
populations. Over the past 15 years, extensive research has produced remarkable
structures called strong amplifiers which guarantee that every beneficial mutation
fixates with high probability. But strong amplification has come at the cost of
considerably delaying the fixation event, which can slow down the overall rate
of evolution. However, the precise relationship between fixation probability and
time has remained elusive. Here we characterize the slowdown effect of strong
amplification. First, we prove that all strong amplifiers must delay the fixation
event at least to some extent. Second, we construct strong amplifiers that delay
the fixation event only marginally as compared to the well-mixed populations.
Our results thus establish a tight relationship between fixation probability and
time: Strong amplification always comes at a cost of a slowdown, but more than
a marginal slowdown is not needed.'

text: We consider the fundamental problem of deriving quantitative bounds on the
probability that a given assertion is violated in a probabilistic program. We
provide automated algorithms that obtain both lower and upper bounds on the assertion
violation probability. The main novelty of our approach is that we prove new and
dedicated fixed-point theorems which serve as the theoretical basis of our algorithms
and enable us to reason about assertion violation bounds in terms of pre and post
fixed-point functions. To synthesize such fixed-points, we devise algorithms that
utilize a wide range of mathematical tools, including repulsing ranking supermartingales,
Hoeffding's lemma, Minkowski decompositions, Jensen's inequality, and convex optimization.
On the theoretical side, we provide (i) the first automated algorithm for lower-bounds
on assertion violation probabilities, (ii) the first complete algorithm for upper-bounds
of exponential form in affine programs, and (iii) provably and significantly tighter
upper-bounds than the previous approaches. On the practical side, we show our
algorithms can handle a wide variety of programs from the literature and synthesize
bounds that are remarkably tighter than previous results, in some cases by thousands
of orders of magnitude.

text: "We consider the fundamental problem of reachability analysis over imperative
programs with real variables. Previous works that tackle reachability are either
unable to handle programs consisting of general loops (e.g. symbolic execution),
or lack completeness guarantees (e.g. abstract interpretation), or are not automated
(e.g. incorrectness logic). In contrast, we propose a novel approach for reachability
analysis that can handle general and complex loops, is complete, and can be entirely
automated for a wide family of programs. Through the notion of Inductive Reachability
Witnesses (IRWs), our approach extends ideas from both invariant generation and
termination to reachability analysis.\r\n\r\nWe first show that our IRW-based
approach is sound and complete for reachability analysis of imperative programs.
Then, we focus on linear and polynomial programs and develop automated methods
for synthesizing linear and polynomial IRWs. In the linear case, we follow the
well-known approaches using Farkas' Lemma. Our main contribution is in the polynomial
case, where we present a push-button semi-complete algorithm. We achieve this
using a novel combination of classical theorems in real algebraic geometry, such
as Putinar's Positivstellensatz and Hilbert's Strong Nullstellensatz. Finally,
our experimental results show we can prove complex reachability objectives over
various benchmarks that were beyond the reach of previous methods."

text: 'We present a faster symbolic algorithm for the following central problem
in probabilistic verification: Compute the maximal end-component (MEC) decomposition
of Markov decision processes (MDPs). This problem generalizes the SCC decomposition
problem of graphs and closed recurrent sets of Markov chains. The model of symbolic
algorithms is widely used in formal verification and model-checking, where access
to the input model is restricted to only symbolic operations (e.g., basic set
operations and computation of one-step neighborhood). For an input MDP with n vertices
and m edges, the classical symbolic algorithm from the 1990s for the MEC decomposition
requires O(n2) symbolic operations and O(1) symbolic space. The only other
symbolic algorithm for the MEC decomposition requires O(nm−−√) symbolic operations
and O(m−−√) symbolic space. A main open question is whether the worst-case O(n2) bound
for symbolic operations can be beaten. We present a symbolic algorithm that requires O˜(n1.5) symbolic
operations and O˜(n−−√) symbolic space. Moreover, the parametrization of our
algorithm provides a trade-off between symbolic operations and symbolic space:
for all 0<ϵ≤1/2 the symbolic algorithm requires O˜(n2−ϵ) symbolic operations
and O˜(nϵ) symbolic space ( O˜ hides poly-logarithmic factors). Using our techniques
we present faster algorithms for computing the almost-sure winning regions of ω
-regular objectives for MDPs. We consider the canonical parity objectives for ω
-regular objectives, and for parity objectives with d -priorities we present
an algorithm that computes the almost-sure winning region with O˜(n2−ϵ) symbolic
operations and O˜(nϵ) symbolic space, for all 0<ϵ≤1/2 .'

which can be computed by a simple dynamic programming algorithm. We consider a
natural generalization of the problem where the stopping times can be chosen according
to a probability distribution, such that the expected stopping time is T, to optimize
the expected total reward. Quite surprisingly we establish inter-reducibility
of the expected stopping-time problem for Markov chains with the Positivity problem
(which is related to the well-known Skolem problem), for which establishing either
decidability or undecidability would be a major breakthrough. Given the hardness
of the exact problem, we consider the approximate version of the problem: we show
that it can be solved in exponential time for Markov chains and in exponential
space for MDPs.'

text: "Repeated idempotent elements are commonly used to characterise iterable behaviours
in abstract models of computation. Therefore, given a monoid M, it is natural
to ask how long a sequence of elements of M needs to be to ensure the presence
of consecutive idempotent factors. This question is formalised through the notion
of the Ramsey function R_M associated to M, obtained by mapping every k ∈ ℕ to
the minimal integer R_M(k) such that every word u ∈ M^* of length R_M(k) contains
k consecutive non-empty factors that correspond to the same idempotent element
of M. In this work, we study the behaviour of the Ramsey function R_M by investigating
the regular \U0001D49F-length of M, defined as the largest size L(M) of a submonoid
of M isomorphic to the set of natural numbers {1,2, …, L(M)} equipped with the
max operation. We show that the regular \U0001D49F-length of M determines the
degree of R_M, by proving that k^L(M) ≤ R_M(k) ≤ (k|M|⁴)^L(M). To allow applications
of this result, we provide the value of the regular \U0001D49F-length of diverse
monoids. In particular, we prove that the full monoid of n × n Boolean matrices,
which is used to express transition monoids of non-deterministic automata, has
a regular \U0001D49F-length of (n²+n+2)/2."

text: 'Stateless model checking (SMC) is one of the standard approaches to the verification
of concurrent programs. As scheduling non-determinism creates exponentially large
spaces of thread interleavings, SMC attempts to partition this space into equivalence
classes and explore only a few representatives from each class. The efficiency
of this approach depends on two factors: (a) the coarseness of the partitioning,
and (b) the time to generate representatives in each class. For this reason, the
search for coarse partitionings that are efficiently explorable is an active research
challenge. In this work we present RVF-SMC , a new SMC algorithm that uses a
novel reads-value-from (RVF) partitioning. Intuitively, two interleavings are
deemed equivalent if they agree on the value obtained in each read event, and
read events induce consistent causal orderings between them. The RVF partitioning
is provably coarser than recent approaches based on Mazurkiewicz and “reads-from”
partitionings. Our experimental evaluation reveals that RVF is quite often a very
effective equivalence, as the underlying partitioning is exponentially coarser
than other approaches. Moreover, RVF-SMC generates representatives very efficiently,
as the reduction in the partitioning is often met with significant speed-ups in
the model checking task.'

text: "In this work we solve the algorithmic problem of consistency verification
for the TSO and PSO memory models given a reads-from map, denoted VTSO-rf and
VPSO-rf, respectively. For an execution of n events over k threads and d variables,
we establish novel bounds that scale as nk+1 for TSO and as nk+1· min(nk2, 2k·
d) for PSO. Moreover, based on our solution to these problems, we develop an SMC
algorithm under TSO and PSO that uses the RF equivalence. The algorithm is exploration-optimal,
in the sense that it is guaranteed to explore each class of the RF partitioning
exactly once, and spends polynomial time per class when k is bounded. Finally,
we implement all our algorithms in the SMC tool Nidhugg, and perform a large number
of experiments over benchmarks from existing literature. Our experimental results
show that our algorithms for VTSO-rf and VPSO-rf provide significant scalability
improvements over standard alternatives. Moreover, when used for SMC, the RF partitioning
is often much coarser than the standard Shasha-Snir partitioning for TSO/PSO,
which yields a significant speedup in the model checking task.\r\n\r\n"

text: The design and verification of concurrent systems remains an open challenge
due to the non-determinism that arises from the inter-process communication. In
particular, concurrent programs are notoriously difficult both to be written correctly
and to be analyzed formally, as complex thread interaction has to be accounted
for. The difficulties are further exacerbated when concurrent programs get executed
on modern-day hardware, which contains various buffering and caching mechanisms
for efficiency reasons. This causes further subtle non-determinism, which can
often produce very unintuitive behavior of the concurrent programs. Model checking
is at the forefront of tackling the verification problem, where the task is to
decide, given as input a concurrent system and a desired property, whether the
system satisfies the property. The inherent state-space explosion problem in model
checking of concurrent systems causes naïve explicit methods not to scale, thus
more inventive methods are required. One such method is stateless model checking
(SMC), which explores in memory-efficient manner the program executions rather
than the states of the program. State-of-the-art SMC is typically coupled with
partial order reduction (POR) techniques, which argue that certain executions
provably produce identical system behavior, thus limiting the amount of executions
one needs to explore in order to cover all possible behaviors. Another method
to tackle the state-space explosion is symbolic model checking, where the considered
techniques operate on a succinct implicit representation of the input system rather
than explicitly accessing the system. In this thesis we present new techniques
for verification of concurrent systems. We present several novel POR methods for
SMC of concurrent programs under various models of semantics, some of which account
for write-buffering mechanisms. Additionally, we present novel algorithms for
symbolic model checking of finite-state concurrent systems, where the desired
property of the systems is to ensure a formally defined notion of fairness.

text: 'We consider planning problems for graphs, Markov Decision Processes (MDPs),
and games on graphs in an explicit state space. While graphs represent the most
basic planning model, MDPs represent interaction with nature and games on graphs
represent interaction with an adversarial environment. We consider two planning
problems with k different target sets: (a) the coverage problem asks whether there
is a plan for each individual target set; and (b) the sequential target reachability
problem asks whether the targets can be reached in a given sequence. For the coverage
problem, we present a linear-time algorithm for graphs, and quadratic conditional
lower bound for MDPs and games on graphs. For the sequential target problem, we
present a linear-time algorithm for graphs, a sub-quadratic algorithm for MDPs,
and a quadratic conditional lower bound for games on graphs. Our results with
conditional lower bounds, based on the boolean matrix multiplication (BMM) conjecture
and strong exponential time hypothesis (SETH), establish (i) model-separation
results showing that for the coverage problem MDPs and games on graphs are harder
than graphs, and for the sequential reachability problem games on graphs are harder
than MDPs and graphs; and (ii) problem-separation results showing that for MDPs
the coverage problem is harder than the sequential target problem.'

text: "We consider the core algorithmic problems related to verification of systems
with respect to three classical quantitative properties, namely, the mean-payoff,
the ratio, and the minimum initial credit for energy property. The algorithmic
problem given a graph and a quantitative property asks to compute the optimal
value (the infimum value over all traces) from every node of the graph. We consider
graphs with bounded treewidth—a class that contains the control flow graphs of
most programs. Let n denote the number of nodes of a graph, m the number of edges
(for bounded treewidth \U0001D45A=\U0001D442(\U0001D45B)) and W the largest absolute
value of the weights. Our main theoretical results are as follows. First, for
the minimum initial credit problem we show that (1) for general graphs the problem
can be solved in \U0001D442(\U0001D45B2⋅\U0001D45A) time and the associated decision
problem in \U0001D442(\U0001D45B⋅\U0001D45A) time, improving the previous known
\U0001D442(\U0001D45B3⋅\U0001D45A⋅log(\U0001D45B⋅\U0001D44A)) and \U0001D442(\U0001D45B2⋅\U0001D45A)
bounds, respectively; and (2) for bounded treewidth graphs we present an algorithm
that requires \U0001D442(\U0001D45B⋅log\U0001D45B) time. Second, for bounded treewidth
graphs we present an algorithm that approximates the mean-payoff value within
a factor of 1+\U0001D716 in time \U0001D442(\U0001D45B⋅log(\U0001D45B/\U0001D716))
as compared to the classical exact algorithms on general graphs that require quadratic
time. Third, for the ratio property we present an algorithm that for bounded treewidth
graphs works in time \U0001D442(\U0001D45B⋅log(|\U0001D44E⋅\U0001D44F|))=\U0001D442(\U0001D45B⋅log(\U0001D45B⋅\U0001D44A)),
when the output is \U0001D44E\U0001D44F, as compared to the previously best known
algorithm on general graphs with running time \U0001D442(\U0001D45B2⋅log(\U0001D45B⋅\U0001D44A)).
We have implemented some of our algorithms and show that they present a significant
speedup on standard benchmarks."

text: 'We present a new approach to proving non-termination of non-deterministic
integer programs. Our technique is rather simple but efficient. It relies on a
purely syntactic reversal of the program''s transition system followed by a constraint-based
invariant synthesis with constraints coming from both the original and the reversed
transition system. The latter task is performed by a simple call to an off-the-shelf
SMT-solver, which allows us to leverage the latest advances in SMT-solving. Moreover,
our method offers a combination of features not present (as a whole) in previous
approaches: it handles programs with non-determinism, provides relative completeness
guarantees and supports programs with polynomial arithmetic. The experiments performed
with our prototype tool RevTerm show that our approach, despite its simplicity
and stronger theoretical guarantees, is at least on par with the state-of-the-art
tools, often achieving a non-trivial improvement under a proper configuration
of its parameters.'

text: 'We consider the almost-sure (a.s.) termination problem for probabilistic
programs, which are a stochastic extension of classical imperative programs. Lexicographic
ranking functions provide a sound and practical approach for termination of non-probabilistic
programs, and their extension to probabilistic programs is achieved via lexicographic
ranking supermartingales (LexRSMs). However, LexRSMs introduced in the previous
work have a limitation that impedes their automation: all of their components
have to be non-negative in all reachable states. This might result in LexRSM not
existing even for simple terminating programs. Our contributions are twofold:
First, we introduce a generalization of LexRSMs which allows for some components
to be negative. This standard feature of non-probabilistic termination proofs
was hitherto not known to be sound in the probabilistic setting, as the soundness
proof requires a careful analysis of the underlying stochastic process. Second,
we present polynomial-time algorithms using our generalized LexRSMs for proving
a.s. termination in broad classes of linear-arithmetic programs.'

text: "In this thesis, we consider several of the most classical and fundamental
problems in static analysis and formal verification, including invariant generation,
reachability analysis, termination analysis of probabilistic programs, data-flow
analysis, quantitative analysis of Markov chains and Markov decision processes,
and the problem of data packing in cache management.\r\nWe use techniques from
parameterized complexity theory, polyhedral geometry, and real algebraic geometry
to significantly improve the state-of-the-art, in terms of both scalability and
completeness guarantees, for the mentioned problems. In some cases, our results
are the first theoretical improvements for the respective problems in two or three
decades."

text: "Indirect reciprocity in evolutionary game theory is a prominent mechanism
for explaining the evolution of cooperation among unrelated individuals. In contrast
to direct reciprocity, which is based on individuals meeting repeatedly, and conditionally
cooperating by using their own experiences, indirect reciprocity is based on individuals’
reputations. If a player helps another, this increases the helper’s public standing,
benefitting them in the future. This lets cooperation in the population emerge
without individuals having to meet more than once. While the two modes of reciprocity
are intertwined, they are difficult to compare. Thus, they are usually studied
in isolation. Direct reciprocity can maintain cooperation with simple strategies,
and is robust against noise even when players do not remember more\r\nthan their
partner’s last action. Meanwhile, indirect reciprocity requires its successful
strategies, or social norms, to be more complex. Exhaustive search previously
identified eight such norms, called the “leading eight”, which excel at maintaining
cooperation. However, as the first result of this thesis, we show that the leading
eight break down once we remove the fundamental assumption that information is
synchronized and public, such that everyone agrees on reputations. Once we consider
a more realistic scenario of imperfect information, where reputations are private,
and individuals occasionally misinterpret or miss observations, the leading eight
do not promote cooperation anymore. Instead, minor initial disagreements can proliferate,
fragmenting populations into subgroups. In a next step, we consider ways to mitigate
this issue. We first explore whether introducing “generosity” can stabilize cooperation
when players use the leading eight strategies in noisy environments. This approach
of modifying strategies to include probabilistic elements for coping with errors
is known to work well in direct reciprocity. However, as we show here, it fails
for the more complex norms of indirect reciprocity. Imperfect information still
prevents cooperation from evolving. On the other hand, we succeeded to show in
this thesis that modifying the leading eight to use “quantitative assessment”,
i.e. tracking reputation scores on a scale beyond good and bad, and making overall
judgments of others based on a threshold, is highly successful, even when noise
increases in the environment. Cooperation can flourish when reputations\r\nare
more nuanced, and players have a broader understanding what it means to be “good.”
Finally, we present a single theoretical framework that unites the two modes of
reciprocity despite their differences. Within this framework, we identify a novel
simple and successful strategy for indirect reciprocity, which can cope with noisy
environments and has an analogue in direct reciprocity. We can also analyze decision
making when different sources of information are available. Our results help highlight
that for sustaining cooperation, already the most simple rules of reciprocity
can be sufficient."

text: Indirect reciprocity is a mechanism for the evolution of cooperation based
on social norms. This mechanism requires that individuals in a population observe
and judge each other’s behaviors. Individuals with a good reputation are more
likely to receive help from others. Previous work suggests that indirect reciprocity
is only effective when all relevant information is reliable and publicly available.
Otherwise, individuals may disagree on how to assess others, even if they all
apply the same social norm. Such disagreements can lead to a breakdown of cooperation.
Here we explore whether the predominantly studied ‘leading eight’ social norms
of indirect reciprocity can be made more robust by equipping them with an element
of generosity. To this end, we distinguish between two kinds of generosity. According
to assessment generosity, individuals occasionally assign a good reputation to
group members who would usually be regarded as bad. According to action generosity,
individuals occasionally cooperate with group members with whom they would usually
defect. Using individual-based simulations, we show that the two kinds of generosity
have a very different effect on the resulting reputation dynamics. Assessment
generosity tends to add to the overall noise and allows defectors to invade. In
contrast, a limited amount of action generosity can be beneficial in a few cases.
However, even when action generosity is beneficial, the respective simulations
do not result in full cooperation. Our results suggest that while generosity can
favor cooperation when individuals use the most simple strategies of reciprocity,
it is disadvantageous when individuals use more complex social norms.

text: Direct and indirect reciprocity are key mechanisms for the evolution of cooperation.
Direct reciprocity means that individuals use their own experience to decide whether
to cooperate with another person. Indirect reciprocity means that they also consider
the experiences of others. Although these two mechanisms are intertwined, they
are typically studied in isolation. Here, we introduce a mathematical framework
that allows us to explore both kinds of reciprocity simultaneously. We show that
the well-known ‘generous tit-for-tat’ strategy of direct reciprocity has a natural
analogue in indirect reciprocity, which we call ‘generous scoring’. Using an equilibrium
analysis, we characterize under which conditions either of the two strategies
can maintain cooperation. With simulations, we additionally explore which kind
of reciprocity evolves when members of a population engage in social learning
to adapt to their environment. Our results draw unexpected connections between
direct and indirect reciprocity while highlighting important differences regarding
their evolvability.

text: 'The Price of Anarchy (PoA) is a well-established game-theoretic concept to
shed light on coordination issues arising in open distributed systems. Leaving
agents to selfishly optimize comes with the risk of ending up in sub-optimal states
(in terms of performance and/or costs), compared to a centralized system design.
However, the PoA relies on strong assumptions about agents'' rationality (e.g.,
resources and information) and interactions, whereas in many distributed systems
agents interact locally with bounded resources. They do so repeatedly over time
(in contrast to "one-shot games"), and their strategies may evolve. Using a more
realistic evolutionary game model, this paper introduces a realized evolutionary
Price of Anarchy (ePoA). The ePoA allows an exploration of equilibrium selection
in dynamic distributed systems with multiple equilibria, based on local interactions
of simple memoryless agents. Considering a fundamental game related to virus propagation
on networks, we present analytical bounds on the ePoA in basic network topologies
and for different strategy update dynamics. In particular, deriving stationary
distributions of the stochastic evolutionary process, we find that the Nash equilibria
are not always the most abundant states, and that different processes can feature
significant off-equilibrium behavior, leading to a significantly higher ePoA compared
to the PoA studied traditionally in the literature. '

text: 'A vector addition system with states (VASS) consists of a finite set of states
and counters. A transition changes the current state to the next state, and every
counter is either incremented, or decremented, or left unchanged. A state and
value for each counter is a configuration; and a computation is an infinite sequence
of configurations with transitions between successive configurations. A probabilistic
VASS consists of a VASS along with a probability distribution over the transitions
for each state. Qualitative properties such as state and configuration reachability
have been widely studied for VASS. In this work we consider multi-dimensional
long-run average objectives for VASS and probabilistic VASS. For a counter, the
cost of a configuration is the value of the counter; and the long-run average
value of a computation for the counter is the long-run average of the costs of
the configurations in the computation. The multi-dimensional long-run average
problem given a VASS and a threshold value for each counter, asks whether there
is a computation such that for each counter the long-run average value for the
counter does not exceed the respective threshold. For probabilistic VASS, instead
of the existence of a computation, we consider whether the expected long-run average
value for each counter does not exceed the respective threshold. Our main results
are as follows: we show that the multi-dimensional long-run average problem (a)
is NP-complete for integer-valued VASS; (b) is undecidable for natural-valued
VASS (i.e., nonnegative counters); and (c) can be solved in polynomial time for
probabilistic integer-valued VASS, and probabilistic natural-valued VASS when
all computations are non-terminating.'

text: Game of Life is a simple and elegant model to study dynamical system over
networks. The model consists of a graph where every vertex has one of two types,
namely, dead or alive. A configuration is a mapping of the vertices to the types.
An update rule describes how the type of a vertex is updated given the types of
its neighbors. In every round, all vertices are updated synchronously, which leads
to a configuration update. While in general, Game of Life allows a broad range
of update rules, we focus on two simple families of update rules, namely, underpopulation
and overpopulation, that model several interesting dynamics studied in the literature.
In both settings, a dead vertex requires at least a desired number of live neighbors
to become alive. For underpopulation (resp., overpopulation), a live vertex requires
at least (resp. at most) a desired number of live neighbors to remain alive. We
study the basic computation problems, e.g., configuration reachability, for these
two families of rules. For underpopulation rules, we show that these problems
can be solved in polynomial time, whereas for overpopulation rules they are PSPACE-complete.

text: A regular language L of finite words is composite if there are regular languages
L₁,L₂,…,L_t such that L = ⋂_{i = 1}^t L_i and the index (number of states in a
minimal DFA) of every language L_i is strictly smaller than the index of L. Otherwise,
L is prime. Primality of regular languages was introduced and studied in [O. Kupferman
and J. Mosheiff, 2015], where the complexity of deciding the primality of the
language of a given DFA was left open, with a doubly-exponential gap between the
upper and lower bounds. We study primality for unary regular languages, namely
regular languages with a singleton alphabet. A unary language corresponds to a
subset of ℕ, making the study of unary prime languages closer to that of primality
in number theory. We show that the setting of languages is richer. In particular,
while every composite number is the product of two smaller numbers, the number
t of languages necessary to decompose a composite unary language induces a strict
hierarchy. In addition, a primality witness for a unary language L, namely a word
that is not in L but is in all products of languages that contain L and have an
index smaller than L’s, may be of exponential length. Still, we are able to characterize
compositionality by structural properties of a DFA for L, leading to a LogSpace
algorithm for primality checking of unary DFAs.

text: Simple stochastic games are turn-based 2½-player games with a reachability
objective. The basic question asks whether one player can ensure reaching a given
target with at least a given probability. A natural extension is games with a
conjunction of such conditions as objective. Despite a plethora of recent results
on the analysis of systems with multiple objectives, the decidability of this
basic problem remains open. In this paper, we present an algorithm approximating
the Pareto frontier of the achievable values to a given precision. Moreover, it
is an anytime algorithm, meaning it can be stopped at any time returning the current
approximation and its error bound.

text: Resources are rarely distributed uniformly within a population. Heterogeneity
in the concentration of a drug, the quality of breeding sites, or wealth can all
affect evolutionary dynamics. In this study, we represent a collection of properties
affecting the fitness at a given location using a color. A green node is rich
in resources while a red node is poorer. More colors can represent a broader spectrum
of resource qualities. For a population evolving according to the birth-death
Moran model, the first question we address is which structures, identified by
graph connectivity and graph coloring, are evolutionarily equivalent. We prove
that all properly two-colored, undirected, regular graphs are evolutionarily equivalent
(where “properly colored” means that no two neighbors have the same color). We
then compare the effects of background heterogeneity on properly two-colored graphs
to those with alternative schemes in which the colors are permuted. Finally, we
discuss dynamic coloring as a model for spatiotemporal resource fluctuations,
and we illustrate that random dynamic colorings often diminish the effects of
background heterogeneity relative to a proper two-coloring.

text: Cooperation is a ubiquitous and beneficial behavioural trait despite being
prone to exploitation by free-riders. Hence, cooperative populations are prone
to invasions by selfish individuals. However, a population consisting of only
free-riders typically does not survive. Thus, cooperators and free-riders often
coexist in some proportion. An evolutionary version of a Snowdrift Game proved
its efficiency in analysing this phenomenon. However, what if the system has already
reached its stable state but was perturbed due to a change in environmental conditions?
Then, individuals may have to re-learn their effective strategies. To address
this, we consider behavioural mistakes in strategic choice execution, which we
refer to as incompetence. Parametrising the propensity to make such mistakes allows
for a mathematical description of learning. We compare strategies based on their
relative strategic advantage relying on both fitness and learning factors. When
strategies are learned at distinct rates, allowing learning according to a prescribed
order is optimal. Interestingly, the strategy with the lowest strategic advantage
should be learnt first if we are to optimise fitness over the learning path. Then,
the differences between strategies are balanced out in order to minimise the effect
of behavioural uncertainty.

text: 'We consider a real-time setting where an environment releases sequences of
firm-deadline tasks, and an online scheduler chooses on-the-fly the ones to execute
on a single processor so as to maximize cumulated utility. The competitive ratio
is a well-known performance measure for the scheduler: it gives the worst-case
ratio, among all possible choices for the environment, of the cumulated utility
of the online scheduler versus an offline scheduler that knows these choices in
advance. Traditionally, competitive analysis is performed by hand, while automated
techniques are rare and only handle static environments with independent tasks.
We present a quantitative-verification framework for precedence-aware competitive
analysis, where task releases may depend on preceding scheduling choices, i.e.,
the environment can respond to scheduling decisions dynamically . We consider
two general classes of precedences: 1) follower precedences force the release
of a dependent task upon the completion of a set of precursor tasks, while and
2) pairing precedences modify the characteristics of a dependent task provided
the completion of a set of precursor tasks. Precedences make competitive analysis
challenging, as the online and offline schedulers operate on diverging sequences.
We make a formal presentation of our framework, and use a GPU-based implementation
to analyze ten well-known schedulers on precedence-based application examples
taken from the existing literature: 1) a handshake protocol (HP); 2) network packet-switching;
3) query scheduling (QS); and 4) a sporadic-interrupt setting. Our experimental
results show that precedences and task parameters can vary drastically the best
scheduler. Our framework thus supports application designers in choosing the best
scheduler among a given set automatically.'

text: In this paper we introduce and study all-pay bidding games, a class of two
player, zero-sum games on graphs. The game proceeds as follows. We place a token
on some vertex in the graph and assign budgets to the two players. Each turn,
each player submits a sealed legal bid (non-negative and below their remaining
budget), which is deducted from their budget and the highest bidder moves the
token onto an adjacent vertex. The game ends once a sink is reached, and Player
1 pays Player 2 the outcome that is associated with the sink. The players attempt
to maximize their expected outcome. Our games model settings where effort (of
no inherent value) needs to be invested in an ongoing and stateful manner. On
the negative side, we show that even in simple games on DAGs, optimal strategies
may require a distribution over bids with infinite support. A central quantity
in bidding games is the ratio of the players budgets. On the positive side, we
show a simple FPTAS for DAGs, that, for each budget ratio, outputs an approximation
for the optimal strategy for that ratio. We also implement it, show that it performs
well, and suggests interesting properties of these games. Then, given an outcome
c, we show an algorithm for finding the necessary and sufficient initial ratio
for guaranteeing outcome c with probability 1 and a strategy ensuring such. Finally,
while the general case has not previously been studied, solving the specific game
in which Player 1 wins iff he wins the first two auctions, has been long stated
as an open question, which we solve.

text: Coinfections with multiple pathogens can result in complex within‐host dynamics
affecting virulence and transmission. While multiple infections are intensively
studied in solitary hosts, it is so far unresolved how social host interactions
interfere with pathogen competition, and if this depends on coinfection diversity.
We studied how the collective disease defences of ants – their social immunity
– influence pathogen competition in coinfections of same or different fungal pathogen
species. Social immunity reduced virulence for all pathogen combinations, but
interfered with spore production only in different‐species coinfections. Here,
it decreased overall pathogen sporulation success while increasing co‐sporulation
on individual cadavers and maintaining a higher pathogen diversity at the community
level. Mathematical modelling revealed that host sanitary care alone can modulate
competitive outcomes between pathogens, giving advantage to fast‐germinating,
thus less grooming‐sensitive ones. Host social interactions can hence modulate
infection dynamics in coinfected group members, thereby altering pathogen communities
at the host level and population level.

text: 'Multiple-environment Markov decision processes (MEMDPs) are MDPs equipped
with not one, but multiple probabilistic transition functions, which represent
the various possible unknown environments. While the previous research on MEMDPs
focused on theoretical properties for long-run average payoff, we study them with
discounted-sum payoff and focus on their practical advantages and applications.
MEMDPs can be viewed as a special case of Partially observable and Mixed observability
MDPs: the state of the system is perfectly observable, but not the environment.
We show that the specific structure of MEMDPs allows for more efficient algorithmic
analysis, in particular for faster belief updates. We demonstrate the applicability
of MEMDPs in several domains. In particular, we formalize the sequential decision-making
approach to contextual recommendation systems as MEMDPs and substantially improve
over the previous MDP approach.'

text: We study turn-based stochastic zero-sum games with lexicographic preferences
over reachability and safety objectives. Stochastic games are standard models
in control, verification, and synthesis of stochastic reactive systems that exhibit
both randomness as well as angelic and demonic non-determinism. Lexicographic
order allows to consider multiple objectives with a strict preference order over
the satisfaction of the objectives. To the best of our knowledge, stochastic games
with lexicographic objectives have not been studied before. We establish determinacy
of such games and present strategy and computational complexity results. For strategy
complexity, we show that lexicographically optimal strategies exist that are deterministic
and memory is only required to remember the already satisfied and violated objectives.
For a constant number of objectives, we show that the relevant decision problem
is in NP∩coNP , matching the current known bound for single objectives; and
in general the decision problem is PSPACE -hard and can be solved in NEXPTIME∩coNEXPTIME
. We present an algorithm that computes the lexicographically optimal strategies
via a reduction to computation of optimal strategies in a sequence of single-objectives
games. We have implemented our algorithm and report experimental results on various
case studies.

text: 'We study relations between evidence theory and S-approximation spaces. Both
theories have their roots in the analysis of Dempsterchr(''39'')s multivalued
mappings and lower and upper probabilities, and have close relations to rough
sets. We show that an S-approximation space, satisfying a monotonicity condition,
can induce a natural belief structure which is a fundamental block in evidence
theory. We also demonstrate that one can induce a natural belief structure on
one set, given a belief structure on another set, if the two sets are related
by a partial monotone S-approximation space. '

text: The fixation probability of a single mutant invading a population of residents
is among the most widely-studied quantities in evolutionary dynamics. Amplifiers
of natural selection are population structures that increase the fixation probability
of advantageous mutants, compared to well-mixed populations. Extensive studies
have shown that many amplifiers exist for the Birth-death Moran process, some
of them substantially increasing the fixation probability or even guaranteeing
fixation in the limit of large population size. On the other hand, no amplifiers
are known for the death-Birth Moran process, and computer-assisted exhaustive
searches have failed to discover amplification. In this work we resolve this disparity,
by showing that any amplification under death-Birth updating is necessarily bounded
and transient. Our boundedness result states that even if a population structure
does amplify selection, the resulting fixation probability is close to that of
the well-mixed population. Our transience result states that for any population
structure there exists a threshold r⋆ such that the population structure ceases
to amplify selection if the mutant fitness advantage r is larger than r⋆. Finally,
we also extend the above results to δ-death-Birth updating, which is a combination
of Birth-death and death-Birth updating. On the positive side, we identify population
structures that maintain amplification for a wide range of values r and δ. These
results demonstrate that amplification of natural selection depends on the specific
mechanisms of the evolutionary process.

text: 'In this thesis we study certain mathematical aspects of evolution. The two
primary forces that drive an evolutionary process are mutation and selection.
Mutation generates new variants in a population. Selection chooses among the variants
depending on the reproductive rates of individuals. Evolutionary processes are
intrinsically random – a new mutation that is initially present in the population
at low frequency can go extinct, even if it confers a reproductive advantage.
The overall rate of evolution is largely determined by two quantities: the probability
that an invading advantageous mutation spreads through the population (called
fixation probability) and the time until it does so (called fixation time). Both
those quantities crucially depend not only on the strength of the invading mutation
but also on the population structure. In this thesis, we aim to understand how
the underlying population structure affects the overall rate of evolution. Specifically,
we study population structures that increase the fixation probability of advantageous
mutants (called amplifiers of selection). Broadly speaking, our results are of
three different types: We present various strong amplifiers, we identify regimes
under which only limited amplification is feasible, and we propose population
structures that provide different tradeoffs between high fixation probability
and short fixation time.'

text: The notion of program sensitivity (aka Lipschitz continuity) specifies that
changes in the program input result in proportional changes to the program output.
For probabilistic programs the notion is naturally extended to expected sensitivity.
A previous approach develops a relational program logic framework for proving
expected sensitivity of probabilistic while loops, where the number of iterations
is fixed and bounded. In this work, we consider probabilistic while loops where
the number of iterations is not fixed, but randomized and depends on the initial
input values. We present a sound approach for proving expected sensitivity of
such programs. Our sound approach is martingale-based and can be automated through
existing martingale-synthesis algorithms. Furthermore, our approach is compositional
for sequential composition of while loops under a mild side condition. We demonstrate
the effectiveness of our approach on several classical examples from Gambler's
Ruin, stochastic hybrid systems and stochastic gradient descent. We also present
experimental results showing that our automated approach can handle various probabilistic
programs in the literature.

text: Markov decision processes (MDPs) are the defacto framework for sequential
decision making in the presence of stochastic uncertainty. A classical optimization
criterion for MDPs is to maximize the expected discounted-sum payoff, which ignores
low probability catastrophic events with highly negative impact on the system.
On the other hand, risk-averse policies require the probability of undesirable
events to be below a given threshold, but they do not account for optimization
of the expected payoff. We consider MDPs with discounted-sum payoff with failure
states which represent catastrophic outcomes. The objective of risk-constrained
planning is to maximize the expected discounted-sum payoff among risk-averse policies
that ensure the probability to encounter a failure state is below a desired threshold.
Our main contribution is an efficient risk-constrained planning algorithm that
combines UCT-like search with a predictor learned through interaction with the
MDP (in the style of AlphaZero) and with a risk-constrained action selection via
linear programming. We demonstrate the effectiveness of our approach with experiments
on classical MDPs from the literature, including benchmarks with an order of 106
states.

text: "Two plane drawings of geometric graphs on the same set of points are called
disjoint compatible if their union is plane and they do not have an edge in common.
For a given set S of 2n points two plane drawings of perfect matchings M1 and
M2 (which do not need to be disjoint nor compatible) are disjoint tree-compatible
if there exists a plane drawing of a spanning tree T on S which is disjoint compatible
to both M1 and M2.\r\nWe show that the graph of all disjoint tree-compatible perfect
geometric matchings on 2n points in convex position is connected if and only if
2n ≥ 10. Moreover, in that case the diameter\r\nof this graph is either 4 or 5,
independent of n."

text: "Interprocedural data-flow analyses form an expressive and useful paradigm
of numerous static analysis applications, such as live variables analysis, alias
analysis and null pointers analysis. The most widely-used framework for interprocedural
data-flow analysis is IFDS, which encompasses distributive data-flow functions
over a finite domain. On-demand data-flow analyses restrict the focus of the analysis
on specific program locations and data facts. This setting provides a natural
split between (i) an offline (or preprocessing) phase, where the program is partially
analyzed and analysis summaries are created, and (ii) an online (or query) phase,
where analysis queries arrive on demand and the summaries are used to speed up
answering queries.\r\nIn this work, we consider on-demand IFDS analyses where
the queries concern program locations of the same procedure (aka same-context
queries). We exploit the fact that flow graphs of programs have low treewidth
to develop faster algorithms that are space and time optimal for many common data-flow
analyses, in both the preprocessing and the query phase. We also use treewidth
to develop query solutions that are embarrassingly parallelizable, i.e. the total
work for answering each query is split to a number of threads such that each thread
performs only a constant amount of work. Finally, we implement a static analyzer
based on our algorithms, and perform a series of on-demand analysis experiments
on standard benchmarks. Our experimental results show a drastic speed-up of the
queries after only a lightweight preprocessing phase, which significantly outperforms
existing techniques."

text: Discrete-time Markov Chains (MCs) and Markov Decision Processes (MDPs) are
two standard formalisms in system analysis. Their main associated quantitative
objectives are hitting probabilities, discounted sum, and mean payoff. Although
there are many techniques for computing these objectives in general MCs/MDPs,
they have not been thoroughly studied in terms of parameterized algorithms, particularly
when treewidth is used as the parameter. This is in sharp contrast to qualitative
objectives for MCs, MDPs and graph games, for which treewidth-based algorithms
yield significant complexity improvements. In this work, we show that treewidth
can also be used to obtain faster algorithms for the quantitative problems. For
an MC with n states and m transitions, we show that each of the classical quantitative
objectives can be computed in O((n+m)⋅t2) time, given a tree decomposition
of the MC with width t. Our results also imply a bound of O(κ⋅(n+m)⋅t2) for
each objective on MDPs, where κ is the number of strategy-iteration refinements
required for the given input and objective. Finally, we make an experimental evaluation
of our new algorithms on low-treewidth MCs and MDPs obtained from the DaCapo benchmark
suite. Our experiments show that on low-treewidth MCs and MDPs, our algorithms
outperform existing well-established methods by one or more orders of magnitude.

text: "We consider the classical problem of invariant generation for programs with
polynomial assignments and focus on synthesizing invariants that are a conjunction
of strict polynomial inequalities. We present a sound and semi-complete method
based on positivstellensaetze, i.e. theorems in semi-algebraic geometry that characterize
positive polynomials over a semi-algebraic set.\r\n\r\nOn the theoretical side,
the worst-case complexity of our approach is subexponential, whereas the worst-case
complexity of the previous complete method (Kapur, ACA 2004) is doubly-exponential.
Even when restricted to linear invariants, the best previous complexity for complete
invariant generation is exponential (Colon et al, CAV 2003). On the practical
side, we reduce the invariant generation problem to quadratic programming (QCLP),
which is a classical optimization problem with many industrial solvers. We demonstrate
the applicability of our approach by providing experimental results on several
academic benchmarks. To the best of our knowledge, the only previous invariant
generation method that provides completeness guarantees for invariants consisting
of polynomial inequalities is (Kapur, ACA 2004), which relies on quantifier elimination
and cannot even handle toy programs such as our running example."

text: "We consider the classic problem of Network Reliability. A network is given
together with a source vertex, one or more target vertices, and probabilities
assigned to each of the edges. Each edge of the network is operable with its associated
probability and the problem is to determine the probability of having at least
one source-to-target path that is entirely composed of operable edges. This problem
is known to be NP-hard.\r\n\r\nWe provide a novel scalable algorithm to solve
the Network Reliability problem when the treewidth of the underlying network is
small. We also show our algorithm’s applicability for real-world transit networks
that have small treewidth, including the metro networks of major cities, such
as London and Tokyo. Our algorithm leverages tree decompositions to shrink the
original graph into much smaller graphs, for which reliability can be efficiently
and exactly computed using a brute force method. To the best of our knowledge,
this is the first exact algorithm for Network Reliability that can scale to handle
real-world instances of the problem."

text: 'The fundamental model-checking problem, given as input a model and a specification,
asks for the algorithmic verification of whether the model satisfies the specification.
Two classical models for reactive systems are graphs and Markov decision processes
(MDPs). A basic specification formalism in the verification of reactive systems
is the strong fairness (aka Streett) objective, where given different types of
requests and corresponding grants, the requirement is that for each type, if the
request event happens infinitely often, then the corresponding grant event must
also happen infinitely often. All omega-regular objectives can be expressed as
Streett objectives and hence they are canonical in verification. Consider graphs/MDPs
with n vertices, m edges, and a Streett objectives with k pairs, and let b denote
the size of the description of the Streett objective for the sets of requests
and grants. The current best-known algorithm for the problem requires time O(min(n^2,
m sqrt{m log n}) + b log n). In this work we present randomized near-linear time
algorithms, with expected running time O~(m + b), where the O~ notation hides
poly-log factors. Our randomized algorithms are near-linear in the size of the
input, and hence optimal up to poly-log factors. '

text: 'A vector addition system with states (VASS) consists of a finite set of states
and counters. A configuration is a state and a value for each counter; a transition
changes the state and each counter is incremented, decremented, or left unchanged.
While qualitative properties such as state and configuration reachability have
been studied for VASS, we consider the long-run average cost of infinite computations
of VASS. The cost of a configuration is for each state, a linear combination of
the counter values. In the special case of uniform cost functions, the linear
combination is the same for all states. The (regular) long-run emptiness problem
is, given a VASS, a cost function, and a threshold value, if there is a (lasso-shaped)
computation such that the long-run average value of the cost function does not
exceed the threshold. For uniform cost functions, we show that the regular long-run
emptiness problem is (a) decidable in polynomial time for integer-valued VASS,
and (b) decidable but nonelementarily hard for natural-valued VASS (i.e., nonnegative
counters). For general cost functions, we show that the problem is (c) NP-complete
for integer-valued VASS, and (d) undecidable for natural-valued VASS. Our most
interesting result is for (c) integer-valued VASS with general cost functions,
where we establish a connection between the regular long-run emptiness problem
and quadratic Diophantine inequalities. The general (nonregular) long-run emptiness
problem is equally hard as the regular problem in all cases except (c), where
it remains open. '

text: 'We study Markov decision processes and turn-based stochastic games with parity
conditions. There are three qualitative winning criteria, namely, sure winning,
which requires all paths to satisfy the condition, almost-sure winning, which
requires the condition to be satisfied with probability 1, and limit-sure winning,
which requires the condition to be satisfied with probability arbitrarily close
to 1. We study the combination of two of these criteria for parity conditions,
e.g., there are two parity conditions one of which must be won surely, and the
other almost-surely. The problem has been studied recently by Berthon et al. for
MDPs with combination of sure and almost-sure winning, under infinite-memory strategies,
and the problem has been established to be in NP cap co-NP. Even in MDPs there
is a difference between finite-memory and infinite-memory strategies. Our main
results for combination of sure and almost-sure winning are as follows: (a) we
show that for MDPs with finite-memory strategies the problem is in NP cap co-NP;
(b) we show that for turn-based stochastic games the problem is co-NP-complete,
both for finite-memory and infinite-memory strategies; and (c) we present algorithmic
results for the finite-memory case, both for MDPs and turn-based stochastic games,
by reduction to non-stochastic parity games. In addition we show that all the
above complexity results also carry over to combination of sure and limit-sure
winning, and results for all other combinations can be derived from existing results
in the literature. Thus we present a complete picture for the study of combinations
of two qualitative winning criteria for parity conditions in MDPs and turn-based
stochastic games. '

text: 'In two-player games on graphs, the players move a token through a graph to
produce a finite or infinite path, which determines the qualitative winner or
quantitative payoff of the game. We study bidding games in which the players bid
for the right to move the token. Several bidding rules were studied previously.
In Richman bidding, in each round, the players simultaneously submit bids, and
the higher bidder moves the token and pays the other player. Poorman bidding is
similar except that the winner of the bidding pays the "bank" rather than the
other player. Taxman bidding spans the spectrum between Richman and poorman bidding.
They are parameterized by a constant tau in [0,1]: portion tau of the winning
bid is paid to the other player, and portion 1-tau to the bank. While finite-duration
(reachability) taxman games have been studied before, we present, for the first
time, results on infinite-duration taxman games. It was previously shown that
both Richman and poorman infinite-duration games with qualitative objectives reduce
to reachability games, and we show a similar result here. Our most interesting
results concern quantitative taxman games, namely mean-payoff games, where poorman
and Richman bidding differ significantly. A central quantity in these games is
the ratio between the two players'' initial budgets. While in poorman mean-payoff
games, the optimal payoff of a player depends on the initial ratio, in Richman
bidding, the payoff depends only on the structure of the game. In both games the
optimal payoffs can be found using (different) probabilistic connections with
random-turn games in which in each turn, instead of bidding, a coin is tossed
to determine which player moves. While the value with Richman bidding equals the
value of a random-turn game with an un-biased coin, with poorman bidding, the
bias in the coin is the initial ratio of the budgets. We give a complete classification
of mean-payoff taxman games that is based on a probabilistic connection: the value
of a taxman bidding game with parameter tau and initial ratio r, equals the value
of a random-turn game that uses a coin with bias F(tau, r) = (r+tau * (1-r))/(1+tau).
Thus, we show that Richman bidding is the exception; namely, for every tau <1,
the value of the game depends on the initial ratio. Our proof technique simplifies
and unifies the previous proof techniques for both Richman and poorman bidding. '

text: We study the termination problem for nondeterministic probabilistic programs.
We consider the bounded termination problem that asks whether the supremum of
the expected termination time over all schedulers is bounded. First, we show that
ranking supermartingales (RSMs) are both sound and complete for proving bounded
termination over nondeterministic probabilistic programs. For nondeterministic
probabilistic programs a previous result claimed that RSMs are not complete for
bounded termination, whereas our result corrects the previous flaw and establishes
completeness with a rigorous proof. Second, we present the first sound approach
to establish lower bounds on expected termination time through RSMs.

text: A controller is a device that interacts with a plant. At each time point,it
reads the plant’s state and issues commands with the goal that the plant oper-ates
optimally. Constructing optimal controllers is a fundamental and challengingproblem.
Machine learning techniques have recently been successfully applied totrain controllers,
yet they have limitations. Learned controllers are monolithic andhard to reason
about. In particular, it is difficult to add features without retraining,to guarantee
any level of performance, and to achieve acceptable performancewhen encountering
untrained scenarios. These limitations can be addressed bydeploying quantitative
run-timeshieldsthat serve as a proxy for the controller.At each time point, the
shield reads the command issued by the controller andmay choose to alter it before
passing it on to the plant. We show how optimalshields that interfere as little
as possible while guaranteeing a desired level ofcontroller performance, can be
generated systematically and automatically usingreactive synthesis. First, we abstract the plant by building a stochastic model.Second,
we consider the learned controller to be a black box. Third, we mea-surecontroller
performanceandshield interferenceby two quantitative run-timemeasures that are
formally defined using weighted automata. Then, the problemof constructing a shield
that guarantees maximal performance with minimal inter-ference is the problem
of finding an optimal strategy in a stochastic2-player game“controller versus
shield” played on the abstract state space of the plant with aquantitative objective
obtained from combining the performance and interferencemeasures. We illustrate
the effectiveness of our approach by automatically con-structing lightweight shields
for learned traffic-light controllers in various roadnetworks. The shields we
generate avoid liveness bugs, improve controller per-formance in untrained and
changing traffic situations, and add features to learnedcontrollers, such as giving
priority to emergency vehicles.

text: Direct reciprocity is a powerful mechanism for the evolution of cooperation
on the basis of repeated interactions1,2,3,4. It requires that interacting individuals
are sufficiently equal, such that everyone faces similar consequences when they
cooperate or defect. Yet inequality is ubiquitous among humans5,6 and is generally
considered to undermine cooperation and welfare7,8,9,10. Most previous models
of reciprocity do not include inequality11,12,13,14,15. These models assume that
individuals are the same in all relevant aspects. Here we introduce a general
framework to study direct reciprocity among unequal individuals. Our model allows
for multiple sources of inequality. Subjects can differ in their endowments, their
productivities and in how much they benefit from public goods. We find that extreme
inequality prevents cooperation. But if subjects differ in productivity, some
endowment inequality can be necessary for cooperation to prevail. Our mathematical
predictions are supported by a behavioural experiment in which we vary the endowments
and productivities of the subjects. We observe that overall welfare is maximized
when the two sources of heterogeneity are aligned, such that more productive individuals
receive higher endowments. By contrast, when endowments and productivities are
misaligned, cooperation quickly breaks down. Our findings have implications for
policy-makers concerned with equity, efficiency and the provisioning of public
goods.

text: "Graph games and Markov decision processes (MDPs) are standard models in reactive
synthesis and verification of probabilistic systems with nondeterminism. The class
of \U0001D714 -regular winning conditions; e.g., safety, reachability, liveness,
parity conditions; provides a robust and expressive specification formalism for
properties that arise in analysis of reactive systems. The resolutions of nondeterminism
in games and MDPs are represented as strategies, and we consider succinct representation
of such strategies. The decision-tree data structure from machine learning retains
the flavor of decisions of strategies and allows entropy-based minimization to
obtain succinct trees. However, in contrast to traditional machine-learning problems
where small errors are allowed, for winning strategies in graph games and MDPs
no error is allowed, and the decision tree must represent the entire strategy.
In this work we propose decision trees with linear classifiers for representation
of strategies in graph games and MDPs. We have implemented strategy representation
using this data structure and we present experimental results for problems on
graph games and MDPs, which show that this new data structure presents a much
more efficient strategy representation as compared to standard decision trees."

text: 'A probabilistic vector addition system with states (pVASS) is a finite state
Markov process augmented with non-negative integer counters that can be incremented
or decremented during each state transition, blocking any behaviour that would
cause a counter to decrease below zero. The pVASS can be used as abstractions
of probabilistic programs with many decidable properties. The use of pVASS as
abstractions requires the presence of nondeterminism in the model. In this paper,
we develop techniques for checking fast termination of pVASS with nondeterminism.
That is, for every initial configuration of size n, we consider the worst expected
number of transitions needed to reach a configuration with some counter negative
(the expected termination time). We show that the problem whether the asymptotic
expected termination time is linear is decidable in polynomial time for a certain
natural class of pVASS with nondeterminism. Furthermore, we show the following
dichotomy: if the asymptotic expected termination time is not linear, then it
is at least quadratic, i.e., in Ω(n2).'

text: The rate of biological evolution depends on the fixation probability and on
the fixation time of new mutants. Intensive research has focused on identifying
population structures that augment the fixation probability of advantageous mutants.
But these amplifiers of natural selection typically increase fixation time. Here
we study population structures that achieve a tradeoff between fixation probability
and time. First, we show that no amplifiers can have an asymptotically lower absorption
time than the well-mixed population. Then we design population structures that
substantially augment the fixation probability with just a minor increase in fixation
time. Finally, we show that those structures enable higher effective rate of evolution
than the well-mixed population provided that the rate of generating advantageous
mutants is relatively low. Our work sheds light on how population structure affects
the rate of evolution. Moreover, our structures could be useful for lab-based,
medical, or industrial applications of evolutionary optimization.

text: 'The verification of concurrent programs remains an open challenge, as thread
interaction has to be accounted for, which leads to state-space explosion. Stateless
model checking battles this problem by exploring traces rather than states of
the program. As there are exponentially many traces, dynamic partial-order reduction
(DPOR) techniques are used to partition the trace space into equivalence classes,
and explore a few representatives from each class. The standard equivalence that
underlies most DPOR techniques is the happens-before equivalence, however recent
works have spawned a vivid interest towards coarser equivalences. The efficiency
of such approaches is a product of two parameters: (i) the size of the partitioning
induced by the equivalence, and (ii) the time spent by the exploration algorithm
in each class of the partitioning. In this work, we present a new equivalence,
called value-happens-before and show that it has two appealing features. First,
value-happens-before is always at least as coarse as the happens-before equivalence,
and can be even exponentially coarser. Second, the value-happens-before partitioning
is efficiently explorable when the number of threads is bounded. We present an
algorithm called value-centric DPOR (VCDPOR), which explores the underlying partitioning
using polynomial time per class. Finally, we perform an experimental evaluation
of VCDPOR on various benchmarks, and compare it against other state-of-the-art
approaches. Our results show that value-happens-before typically induces a significant
reduction in the size of the underlying partitioning, which leads to a considerable
reduction in the running time for exploring the whole partitioning.'

text: Graph planning gives rise to fundamental algorithmic questions such as shortest
path, traveling salesman problem, etc. A classical problem in discrete planning
is to consider a weighted graph and construct a path that maximizes the sum of
weights for a given time horizon T. However, in many scenarios, the time horizon
is not fixed, but the stopping time is chosen according to some distribution such
that the expected stopping time is T. If the stopping time distribution is not
known, then to ensure robustness, the distribution is chosen by an adversary,
to represent the worst-case scenario. A stationary plan for every vertex always
chooses the same outgoing edge. For fixed horizon or fixed stopping-time distribution,
stationary plans are not sufficient for optimality. Quite surprisingly we show
that when an adversary chooses the stopping-time distribution with expected stopping
time T, then stationary plans are sufficient. While computing optimal stationary
plans for fixed horizon is NP-complete, we show that computing optimal stationary
plans under adversarial stopping-time distribution can be achieved in polynomial
time. Consequently, our polynomial-time algorithm for adversarial stopping time
also computes an optimal plan among all possible plans.

text: "The input to the token swapping problem is a graph with vertices v1, v2,
. . . , vn, and n tokens with labels 1,2, . . . , n, one on each vertex. The
goal is to get token i to vertex vi for all i= 1, . . . , n using a minimum number
of swaps, where a swap exchanges the tokens on the endpoints of an edge.Token
swapping on a tree, also known as “sorting with a transposition tree,” is not
known to be in P nor NP-complete. We present some partial results:\r\n1. An
optimum swap sequence may need to perform a swap on a leaf vertex that has the
correct token (a “happy leaf”), disproving a conjecture of Vaughan.\r\n2. Any
algorithm that fixes happy leaves—as all known approximation algorithms for the
problem do—has approximation factor at least 4/3. Furthermore, the two best-known
2-approximation algorithms have approximation factor exactly 2.\r\n3. A generalized
problem—weighted coloured token swapping—is NP-complete on trees, but solvable
in polynomial time on paths and stars. In this version, tokens and vertices
\ have colours, and colours have weights. The goal is to get every
token to a vertex of the same colour, and the cost of a swap is the sum of the
weights of the two tokens involved."

text: "In this work, we consider the almost-sure termination problem for probabilistic
programs that asks whether a\r\ngiven probabilistic program terminates with probability
1. Scalable approaches for program analysis often\r\nrely on modularity as their
theoretical basis. In non-probabilistic programs, the classical variant rule (V-rule)\r\nof
Floyd-Hoare logic provides the foundation for modular analysis. Extension of this
rule to almost-sure\r\ntermination of probabilistic programs is quite tricky,
and a probabilistic variant was proposed in [16]. While the\r\nproposed probabilistic
variant cautiously addresses the key issue of integrability, we show that the
proposed\r\nmodular rule is still not sound for almost-sure termination of probabilistic
programs.\r\nBesides establishing unsoundness of the previous rule, our contributions
are as follows: First, we present a\r\nsound modular rule for almost-sure termination
of probabilistic programs. Our approach is based on a novel\r\nnotion of descent
supermartingales. Second, for algorithmic approaches, we consider descent supermartingales\r\nthat
are linear and show that they can be synthesized in polynomial time. Finally,
we present experimental\r\nresults on a variety of benchmarks and several natural
examples that model various types of nested while\r\nloops in probabilistic programs
and demonstrate that our approach is able to efficiently prove their almost-sure\r\ntermination

text: 'There is a huge gap between the speeds of modern caches and main memories,
and therefore cache misses account for a considerable loss of efficiency in programs.
The predominant technique to address this issue has been Data Packing: data elements
that are frequently accessed within time proximity are packed into the same cache
block, thereby minimizing accesses to the main memory. We consider the algorithmic
problem of Data Packing on a two-level memory system. Given a reference sequence
R of accesses to data elements, the task is to partition the elements into cache
blocks such that the number of cache misses on R is minimized. The problem is
notoriously difficult: it is NP-hard even when the cache has size 1, and is hard
to approximate for any cache size larger than 4. Therefore, all existing techniques
for Data Packing are based on heuristics and lack theoretical guarantees. In this
work, we present the first positive theoretical results for Data Packing, along
with new and stronger negative results. We consider the problem under the lens
of the underlying access hypergraphs, which are hypergraphs of affinities between
the data elements, where the order of an access hypergraph corresponds to the
size of the affinity group. We study the problem parameterized by the treewidth
of access hypergraphs, which is a standard notion in graph theory to measure the
closeness of a graph to a tree. Our main results are as follows: We show there
is a number q* depending on the cache parameters such that (a) if the access hypergraph
of order q* has constant treewidth, then there is a linear-time algorithm for
Data Packing; (b)the Data Packing problem remains NP-hard even if the access hypergraph
of order q*-1 has constant treewidth. Thus, we establish a fine-grained dichotomy
depending on a single parameter, namely, the highest order among access hypegraphs
that have constant treewidth; and establish the optimal value q* of this parameter.
Finally, we present an experimental evaluation of a prototype implementation of
our algorithm. Our results demonstrate that, in practice, access hypergraphs of
many commonly-used algorithms have small treewidth. We compare our approach with
several state-of-the-art heuristic-based algorithms and show that our algorithm
leads to significantly fewer cache-misses. '

text: In today's programmable blockchains, smart contracts are limited to being
deterministic and non-probabilistic. This lack of randomness is a consequential
limitation, given that a wide variety of real-world financial contracts, such
as casino games and lotteries, depend entirely on randomness. As a result, several
ad-hoc random number generation approaches have been developed to be used in smart
contracts. These include ideas such as using an oracle or relying on the block
hash. However, these approaches are manipulatable, i.e. their output can be tampered
with by parties who might not be neutral, such as the owner of the oracle or the
miners.We propose a novel game-theoretic approach for generating provably unmanipulatable
pseudorandom numbers on the blockchain. Our approach allows smart contracts to
access a trustworthy source of randomness that does not rely on potentially compromised
miners or oracles, hence enabling the creation of a new generation of smart contracts
that are not limited to being non-probabilistic and can be drawn from the much
more general class of probabilistic programs.

text: 'In today''s cryptocurrencies, Hashcash proof of work is the most commonly-adopted
approach to mining. In Hashcash, when a miner decides to add a block to the chain,
she has to solve the difficult computational puzzle of inverting a hash function.
While Hashcash has been successfully adopted in both Bitcoin and Ethereum, it
has attracted significant and harsh criticism due to its massive waste of electricity,
its carbon footprint and environmental effects, and the inherent lack of usefulness
in inverting a hash function. Various other mining protocols have been suggested,
including proof of stake, in which a miner''s chance of adding the next block
is proportional to her current balance. However, such protocols lead to a higher
entry cost for new miners who might not still have any stake in the cryptocurrency,
and can in the worst case lead to an oligopoly, where the rich have complete control
over mining. In this paper, we propose Hybrid Mining: a new mining protocol that
combines solving real-world useful problems with Hashcash. Our protocol allows
new miners to join the network by taking part in Hashcash mining without having
to own an initial stake. It also allows nodes of the network to submit hard computational
problems whose solutions are of interest in the real world, e.g.~protein folding
problems. Then, miners can choose to compete in solving these problems, in lieu
of Hashcash, for adding a new block. Hence, Hybrid Mining incentivizes miners
to solve useful problems, such as hard computational problems arising in biology,
in a distributed manner. It also gives researchers in other areas an easy-to-use
tool to outsource their hard computations to the blockchain network, which has
enormous computational power, by paying a reward to the miner who solves the problem
for them. Moreover, our protocol provides strong security guarantees and is at
least as resilient to double spending as Bitcoin.'

text: "We consider the problem of expected cost analysis over nondeterministic probabilistic
programs,\r\nwhich aims at automated methods for analyzing the resource-usage
of such programs.\r\nPrevious approaches for this problem could only handle nonnegative
bounded costs.\r\nHowever, in many scenarios, such as queuing networks or analysis
of cryptocurrency protocols,\r\nboth positive and negative costs are necessary
and the costs are unbounded as well.\r\n\r\nIn this work, we present a sound and
efficient approach to obtain polynomial bounds on the\r\nexpected accumulated
cost of nondeterministic probabilistic programs.\r\nOur approach can handle (a)
general positive and negative costs with bounded updates in\r\nvariables; and
(b) nonnegative costs with general updates to variables.\r\nWe show that several
natural examples which could not be\r\nhandled by previous approaches are captured
in our framework.\r\n\r\nMoreover, our approach leads to an efficient polynomial-time
algorithm, while no\r\nprevious approach for cost analysis of probabilistic programs
could guarantee polynomial runtime.\r\nFinally, we show the effectiveness of our
approach using experimental results on a variety of programs for which we efficiently
synthesize tight resource-usage bounds."

text: "Smart contracts are programs that are stored and executed on the Blockchain
and can receive, manage and transfer money (cryptocurrency units). Two important
problems regarding smart contracts are formal analysis and compiler optimization.
Formal analysis is extremely important, because smart contracts hold funds worth
billions of dollars and their code is immutable after deployment. Hence, an undetected
bug can cause significant financial losses. Compiler optimization is also crucial,
because every action of a smart contract has to be executed by every node in the
Blockchain network. Therefore, optimizations in compiling smart contracts can
lead to significant savings in computation, time and energy.\r\n\r\nTwo classical
approaches in program analysis and compiler optimization are intraprocedural and
interprocedural analysis. In intraprocedural analysis, each function is analyzed
separately, while interprocedural analysis considers the entire program. In both
cases, the analyses are usually reduced to graph problems over the control flow
graph (CFG) of the program. These graph problems are often computationally expensive.
Hence, there has been ample research on exploiting structural properties of CFGs
for efficient algorithms. One such well-studied property is the treewidth, which
is a measure of tree-likeness of graphs. It is known that intraprocedural CFGs
of structured programs have treewidth at most 6, whereas the interprocedural treewidth
cannot be bounded. This result has been used as a basis for many efficient intraprocedural
analyses.\r\n\r\nIn this paper, we explore the idea of exploiting the treewidth
of smart contracts for formal analysis and compiler optimization. First, similar
to classical programs, we show that the intraprocedural treewidth of structured
Solidity and Vyper smart contracts is at most 9. Second, for global analysis,
we prove that the interprocedural treewidth of structured smart contracts is bounded
by 10 and, in sharp contrast with classical programs, treewidth-based algorithms
can be easily applied for interprocedural analysis. Finally, we supplement our
theoretical results with experiments using a tool we implemented for computing
treewidth of smart contracts and show that the treewidth is much lower in practice.
We use 36,764 real-world Ethereum smart contracts as benchmarks and find that
they have an average treewidth of at most 3.35 for the intraprocedural case and
3.65 for the interprocedural case.\r\n"

text: "Interprocedural analysis is at the heart of numerous applications in programming
languages, such as alias analysis, constant propagation, and so on. Recursive
state machines (RSMs) are standard models for interprocedural analysis. We consider
a general framework with RSMs where the transitions are labeled from a semiring
and path properties are algebraic with semiring operations. RSMs with algebraic
path properties can model interprocedural dataflow analysis problems, the shortest
path problem, the most probable path problem, and so on. The traditional algorithms
for interprocedural analysis focus on path properties where the starting point
is fixed as the entry point of a specific method. In this work, we consider possible
multiple queries as required in many applications such as in alias analysis. The
study of multiple queries allows us to bring in an important algorithmic distinction
between the resource usage of the one-time preprocessing vs for each individual
query. The second aspect we consider is that the control flow graphs for most
programs have constant treewidth.\r\n\r\nOur main contributions are simple and
implementable algorithms that support multiple queries for algebraic path properties
for RSMs that have constant treewidth. Our theoretical results show that our algorithms
have small additional one-time preprocessing but can answer subsequent queries
significantly faster as compared to the current algorithmic solutions for interprocedural
dataflow analysis. We have also implemented our algorithms and evaluated their
performance for performing on-demand interprocedural dataflow analysis on various
domains, such as for live variable analysis and reaching definitions, on a standard
benchmark set. Our experimental results align with our theoretical statements
and show that after a lightweight preprocessing, on-demand queries are answered
much faster than the standard existing algorithmic approaches.\r\n"

text: "We study the problem of developing efficient approaches for proving\r\nworst-case
bounds of non-deterministic recursive programs. Ranking functions\r\nare sound
and complete for proving termination and worst-case bounds of\r\nnonrecursive
programs. First, we apply ranking functions to recursion,\r\nresulting in measure
functions. We show that measure functions provide a sound\r\nand complete approach
to prove worst-case bounds of non-deterministic recursive\r\nprograms. Our second
contribution is the synthesis of measure functions in\r\nnonpolynomial forms.
We show that non-polynomial measure functions with\r\nlogarithm and exponentiation
can be synthesized through abstraction of\r\nlogarithmic or exponentiation terms,
Farkas' Lemma, and Handelman's Theorem\r\nusing linear programming. While previous
methods obtain worst-case polynomial\r\nbounds, our approach can synthesize bounds
of the form $\\mathcal{O}(n\\log n)$\r\nas well as $\\mathcal{O}(n^r)$ where $r$
is not an integer. We present\r\nexperimental results to demonstrate that our
approach can obtain efficiently\r\nworst-case bounds of classical recursive algorithms
such as (i) Merge-Sort, the\r\ndivide-and-conquer algorithm for the Closest-Pair
problem, where we obtain\r\n$\\mathcal{O}(n \\log n)$ worst-case bound, and (ii)
Karatsuba's algorithm for\r\npolynomial multiplication and Strassen's algorithm
for matrix multiplication,\r\nwhere we obtain $\\mathcal{O}(n^r)$ bound such that
$r$ is not an integer and\r\nclose to the best-known bounds for the respective
algorithms."

text: 'Solving parity games, which are equivalent to modal μ-calculus model checking,
is a central algorithmic problem in formal methods, with applications in reactive
synthesis, program repair, verification of branching-time properties, etc. Besides
the standard compu- tation model with the explicit representation of games, another
important theoretical model of computation is that of set-based symbolic algorithms.
Set-based symbolic algorithms use basic set operations and one-step predecessor
operations on the implicit description of games, rather than the explicit representation.
The significance of symbolic algorithms is that they provide scalable algorithms
for large finite-state systems, as well as for infinite-state systems with finite
quotient. Consider parity games on graphs with n vertices and parity conditions
with d priorities. While there is a rich literature of explicit algorithms for
parity games, the main results for set-based symbolic algorithms are as follows:
(a) the basic algorithm that requires O(nd) symbolic operations and O(d) symbolic
space; and (b) an improved algorithm that requires O(nd/3+1) symbolic operations
and O(n) symbolic space. In this work, our contributions are as follows: (1) We
present a black-box set-based symbolic algorithm based on the explicit progress
measure algorithm. Two important consequences of our algorithm are as follows:
(a) a set-based symbolic algorithm for parity games that requires quasi-polynomially
many symbolic operations and O(n) symbolic space; and (b) any future improvement
in progress measure based explicit algorithms immediately imply an efficiency
improvement in our set-based symbolic algorithm for parity games. (2) We present
a set-based symbolic algorithm that requires quasi-polynomially many symbolic
operations and O(d · log n) symbolic space. Moreover, for the important special
case of d ≤ log n, our algorithm requires only polynomially many symbolic operations
and poly-logarithmic symbolic space.'

text: Probabilistic programs extend classical imperative programs with real-valued
random variables and random branching. The most basic liveness property for such
programs is the termination property. The qualitative (aka almost-sure) termination
problem asks whether a given program program terminates with probability 1. While
ranking functions provide a sound and complete method for non-probabilistic programs,
the extension of them to probabilistic programs is achieved via ranking supermartingales
(RSMs). Although deep theoretical results have been established about RSMs, their
application to probabilistic programs with nondeterminism has been limited only
to programs of restricted control-flow structure. For non-probabilistic programs,
lexicographic ranking functions provide a compositional and practical approach
for termination analysis of real-world programs. In this work we introduce lexicographic
RSMs and show that they present a sound method for almost-sure termination of
probabilistic programs with nondeterminism. We show that lexicographic RSMs provide
a tool for compositional reasoning about almost-sure termination, and for probabilistic
programs with linear arithmetic they can be synthesized efficiently (in polynomial
time). We also show that with additional restrictions even asymptotic bounds on
expected termination time can be obtained through lexicographic RSMs. Finally,
we present experimental results on benchmarks adapted from previous work to demonstrate
the effectiveness of our approach.

text: Graph-based games are an important tool in computer science. They have applications
in synthesis, verification, refinement, and far beyond. We review graphbased games
with objectives on infinite plays. We give definitions and algorithms to solve
the games and to give a winning strategy. The objectives we consider are mostly
Boolean, but we also look at quantitative graph-based games and their objectives.
Synthesis aims to turn temporal logic specifications into correct reactive systems.
We explain the reduction of synthesis to graph-based games (or equivalently tree
automata) using synthesis of LTL specifications as an example. We treat the classical
approach that uses determinization of parity automata and more modern approaches.

text: Responsiveness—the requirement that every request to a system be eventually
handled—is one of the fundamental liveness properties of a reactive system. Average
response time is a quantitative measure for the responsiveness requirement used
commonly in performance evaluation. We show how average response time can be computed
on state-transition graphs, on Markov chains, and on game graphs. In all three
cases, we give polynomial-time algorithms.

text: Direct reciprocity is a mechanism for cooperation among humans. Many of our
daily interactions are repeated. We interact repeatedly with our family, friends,
colleagues, members of the local and even global community. In the theory of repeated
games, it is a tacit assumption that the various games that a person plays simultaneously
have no effect on each other. Here we introduce a general framework that allows
us to analyze “crosstalk” between a player’s concurrent games. In the presence
of crosstalk, the action a person experiences in one game can alter the person’s
decision in another. We find that crosstalk impedes the maintenance of cooperation
and requires stronger levels of forgiveness. The magnitude of the effect depends
on the population structure. In more densely connected social groups, crosstalk
has a stronger effect. A harsh retaliator, such as Tit-for-Tat, is unable to counteract
crosstalk. The crosstalk framework provides a unified interpretation of direct
and upstream reciprocity in the context of repeated games.

text: 'Vector Addition Systems with States (VASS) provide a well-known and fundamental
model for the analysis of concurrent processes, parameterized systems, and are
also used as abstract models of programs in resource bound analysis. In this paper
we study the problem of obtaining asymptotic bounds on the termination time of
a given VASS. In particular, we focus on the practically important case of obtaining
polynomial bounds on termination time. Our main contributions are as follows:
First, we present a polynomial-time algorithm for deciding whether a given VASS
has a linear asymptotic complexity. We also show that if the complexity of a VASS
is not linear, it is at least quadratic. Second, we classify VASS according to
quantitative properties of their cycles. We show that certain singularities in
these properties are the key reason for non-polynomial asymptotic complexity of
VASS. In absence of singularities, we show that the asymptotic complexity is always
polynomial and of the form Θ(nk), for some integer k d, where d is the dimension
of the VASS. We present a polynomial-time algorithm computing the optimal k. For
general VASS, the same algorithm, which is based on a complete technique for the
construction of ranking functions in VASS, produces a valid lower bound, i.e.,
a k such that the termination complexity is (nk). Our results are based on new
insights into the geometry of VASS dynamics, which hold the potential for further
applicability to VASS analysis.'

text: 'Social dilemmas occur when incentives for individuals are misaligned with
group interests 1-7 . According to the ''tragedy of the commons'', these misalignments
can lead to overexploitation and collapse of public resources. The resulting behaviours
can be analysed with the tools of game theory 8 . The theory of direct reciprocity
9-15 suggests that repeated interactions can alleviate such dilemmas, but previous
work has assumed that the public resource remains constant over time. Here we
introduce the idea that the public resource is instead changeable and depends
on the strategic choices of individuals. An intuitive scenario is that cooperation
increases the public resource, whereas defection decreases it. Thus, cooperation
allows the possibility of playing a more valuable game with higher payoffs, whereas
defection leads to a less valuable game. We analyse this idea using the theory
of stochastic games 16-19 and evolutionary game theory. We find that the dependence
of the public resource on previous interactions can greatly enhance the propensity
for cooperation. For these results, the interaction between reciprocity and payoff
feedback is crucial: neither repeated interactions in a constant environment nor
single interactions in a changing environment yield similar cooperation rates.
Our framework shows which feedbacks between exploitation and environment - either

text: A model of computation that is widely used in the formal analysis of reactive
systems is symbolic algorithms. In this model the access to the input graph is
restricted to consist of symbolic operations, which are expensive in comparison
to the standard RAM operations. We give lower bounds on the number of symbolic
operations for basic graph problems such as the computation of the strongly connected
components and of the approximate diameter as well as for fundamental problems
in model checking such as safety, liveness, and coliveness. Our lower bounds are
linear in the number of vertices of the graph, even for constant-diameter graphs.
For none of these problems lower bounds on the number of symbolic operations were
known before. The lower bounds show an interesting separation of these problems
from the reachability problem, which can be solved with O(D) symbolic operations,
where D is the diameter of the graph. Additionally we present an approximation
algorithm for the graph diameter which requires Õ(n/D) symbolic steps to achieve
a (1 +ϵ)-approximation for any constant > 0. This compares to O(n/D) symbolic
steps for the (naive) exact algorithm and O(D) symbolic steps for a 2-approximation.
Finally we also give a refined analysis of the strongly connected components algorithms
of [15], showing that it uses an optimal number of symbolic steps that is proportional
to the sum of the diameters of the strongly connected components.

text: We study the almost-sure termination problem for probabilistic programs. First,
we show that supermartingales with lower bounds on conditional absolute difference
provide a sound approach for the almost-sure termination problem. Moreover, using
this approach we can obtain explicit optimal bounds on tail probabilities of non-termination
within a given number of steps. Second, we present a new approach based on Central
Limit Theorem for the almost-sure termination problem, and show that this approach
can establish almost-sure termination of programs which none of the existing approaches
can handle. Finally, we discuss algorithmic approaches for the two above methods
that lead to automated analysis techniques for almost-sure termination of probabilistic
programs.

text: 'Reciprocity is a major factor in human social life and accounts for a large
part of cooperation in our communities. Direct reciprocity arises when repeated
interactions occur between the same individuals. The framework of iterated games
formalizes this phenomenon. Despite being introduced more than five decades ago,
the concept keeps offering beautiful surprises. Recent theoretical research driven
by new mathematical tools has proposed a remarkable dichotomy among the crucial
strategies: successful individuals either act as partners or as rivals. Rivals
strive for unilateral advantages by applying selfish or extortionate strategies.
Partners aim to share the payoff for mutual cooperation, but are ready to fight
back when being exploited. Which of these behaviours evolves depends on the environment.
Whereas small population sizes and a limited number of rounds favour rivalry,
partner strategies are selected when populations are large and relationships stable.
Only partners allow for evolution of cooperation, while the rivals’ attempt to
put themselves first leads to defection. Hilbe et al. synthesize recent theoretical
work on zero-determinant and ‘rival’ versus ‘partner’ strategies in social dilemmas.
They describe the environments under which these contrasting selfish or cooperative
strategies emerge in evolution.'

text: 'Markov Decision Processes (MDPs) are a popular class of models suitable for
solving control decision problems in probabilistic reactive systems. We consider
parametric MDPs (pMDPs) that include parameters in some of the transition probabilities
to account for stochastic uncertainties of the environment such as noise or input
disturbances. We study pMDPs with reachability objectives where the parameter
values are unknown and impossible to measure directly during execution, but there
is a probability distribution known over the parameter values. We study for the
first time computing parameter-independent strategies that are expectation optimal,
i.e., optimize the expected reachability probability under the probability distribution
over the parameters. We present an encoding of our problem to partially observable
MDPs (POMDPs), i.e., a reduction of our problem to computing optimal strategies
in POMDPs. We evaluate our method experimentally on several benchmarks: a motivating
(repeated) learner model; a series of benchmarks of varying configurations of
a robot moving on a grid; and a consensus protocol.'

text: Graph games played by two players over finite-state graphs are central in
many problems in computer science. In particular, graph games with ω -regular
winning conditions, specified as parity objectives, which can express properties
such as safety, liveness, fairness, are the basic framework for verification and
synthesis of reactive systems. The decisions for a player at various states of
the graph game are represented as strategies. While the algorithmic problem for
solving graph games with parity objectives has been widely studied, the most prominent
data-structure for strategy representation in graph games has been binary decision
diagrams (BDDs). However, due to the bit-level representation, BDDs do not retain
the inherent flavor of the decisions of strategies, and are notoriously hard to
minimize to obtain succinct representation. In this work we propose decision trees
for strategy representation in graph games. Decision trees retain the flavor of
decisions of strategies and allow entropy-based minimization to obtain succinct
trees. However, decision trees work in settings (e.g., probabilistic models) where
errors are allowed, and overfitting of data is typically avoided. In contrast,
for strategies in graph games no error is allowed, and the decision tree must
represent the entire strategy. We develop new techniques to extend decision trees
to overcome the above obstacles, while retaining the entropy-based techniques
to obtain succinct trees. We have implemented our techniques to extend the existing
decision tree solvers. We present experimental results for problems in reactive
synthesis to show that decision trees provide a much more efficient data-structure
for strategy representation as compared to BDDs.

text: 'Given a model and a specification, the fundamental model-checking problem
asks for algorithmic verification of whether the model satisfies the specification.
We consider graphs and Markov decision processes (MDPs), which are fundamental
models for reactive systems. One of the very basic specifications that arise in
verification of reactive systems is the strong fairness (aka Streett) objective.
Given different types of requests and corresponding grants, the objective requires
that for each type, if the request event happens infinitely often, then the corresponding
grant event must also happen infinitely often. All ω -regular objectives can be
expressed as Streett objectives and hence they are canonical in verification.
To handle the state-space explosion, symbolic algorithms are required that operate
on a succinct implicit representation of the system rather than explicitly accessing
the system. While explicit algorithms for graphs and MDPs with Streett objectives
have been widely studied, there has been no improvement of the basic symbolic
algorithms. The worst-case numbers of symbolic steps required for the basic symbolic
algorithms are as follows: quadratic for graphs and cubic for MDPs. In this work
we present the first sub-quadratic symbolic algorithm for graphs with Streett
objectives, and our algorithm is sub-quadratic even for MDPs. Based on our algorithmic
insights we present an implementation of the new symbolic approach and show that
it improves the existing approach on several academic benchmark examples.'

text: People sometimes make their admirable deeds and accomplishments hard to spot,
such as by giving anonymously or avoiding bragging. Such ‘buried’ signals are
hard to reconcile with standard models of signalling or indirect reciprocity,
which motivate costly pro-social behaviour by reputational gains. To explain these
phenomena, we design a simple game theory model, which we call the signal-burying
game. This game has the feature that senders can bury their signal by deliberately
reducing the probability of the signal being observed. If the signal is observed,
however, it is identified as having been buried. We show under which conditions
buried signals can be maintained, using static equilibrium concepts and calculations
of the evolutionary dynamics. We apply our analysis to shed light on a number
of otherwise puzzling social phenomena, including modesty, anonymous donations,
subtlety in art and fashion, and overeagerness.
