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
naturally occurring or designed - help to overcome social dilemmas.'

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.

text: "The Big Match is a multi-stage two-player game. In each stage Player 1 hides
one or two pebbles in his hand, and his opponent has to guess that number; Player
1 loses a point if Player 2 is correct, and otherwise he wins a point. As soon
as Player 1 hides one pebble, the players cannot change their choices in any future
stage.\r\nBlackwell and Ferguson (1968) give an ε-optimal strategy for Player
1 that hides, in each stage, one pebble with a probability that depends on the
entire past history. Any strategy that depends just on the clock or on a finite
memory is worthless. The long-standing natural open problem has been whether every
strategy that depends just on the clock and a finite memory is worthless. We prove
that there is such a strategy that is ε-optimal. In fact, we show that just two
states of memory are sufficient.\r\n"

text: 'In this article, we consider the termination problem of probabilistic programs
with real-valued variables. Thequestions concerned are: qualitative ones that
ask (i) whether the program terminates with probability 1(almost-sure termination)
and (ii) whether the expected termination time is finite (finite termination);
andquantitative ones that ask (i) to approximate the expected termination time
(expectation problem) and (ii) tocompute a boundBsuch that the probability not
to terminate afterBsteps decreases exponentially (con-centration problem). To
solve these questions, we utilize the notion of ranking supermartingales, which
isa powerful approach for proving termination of probabilistic programs. In detail,
we focus on algorithmicsynthesis of linear ranking-supermartingales over affine
probabilistic programs (Apps) with both angelic anddemonic non-determinism. An
important subclass of Apps is LRApp which is defined as the class of all Appsover
which a linear ranking-supermartingale exists.Our main contributions are as follows.
Firstly, we show that the membership problem of LRApp (i) canbe decided in polynomial
time for Apps with at most demonic non-determinism, and (ii) isNP-hard and inPSPACEfor
Apps with angelic non-determinism. Moreover, theNP-hardness result holds already
for Appswithout probability and demonic non-determinism. Secondly, we show that
the concentration problem overLRApp can be solved in the same complexity as for
the membership problem of LRApp. Finally, we show thatthe expectation problem
over LRApp can be solved in2EXPTIMEand isPSPACE-hard even for Apps withoutprobability
and non-determinism (i.e., deterministic programs). Our experimental results demonstrate
theeffectiveness of our approach to answer the qualitative and quantitative questions
over Apps with at mostdemonic non-determinism.'

text: 'Partially observable Markov decision processes (POMDPs) are the standard
models for planning under uncertainty with both finite and infinite horizon. Besides
the well-known discounted-sum objective, indefinite-horizon objective (aka Goal-POMDPs)
is another classical objective for POMDPs. In this case, given a set of target
states and a positive cost for each transition, the optimization objective is
to minimize the expected total cost until a target state is reached. In the literature,
RTDP-Bel or heuristic search value iteration (HSVI) have been used for solving
Goal-POMDPs. Neither of these algorithms has theoretical convergence guarantees,
and HSVI may even fail to terminate its trials. We give the following contributions:
(1) We discuss the challenges introduced in Goal-POMDPs and illustrate how they
prevent the original HSVI from converging. (2) We present a novel algorithm inspired
by HSVI, termed Goal-HSVI, and show that our algorithm has convergence guarantees.
(3) We show that Goal-HSVI outperforms RTDP-Bel on a set of well-known examples.'

text: Partially-observable Markov decision processes (POMDPs) with discounted-sum
payoff are a standard framework to model a wide range of problems related to decision
making under uncertainty. Traditionally, the goal has been to obtain policies
that optimize the expectation of the discounted-sum payoff. A key drawback of
the expectation measure is that even low probability events with extreme payoff
can significantly affect the expectation, and thus the obtained policies are not
necessarily risk-averse. An alternate approach is to optimize the probability
that the payoff is above a certain threshold, which allows obtaining risk-averse
policies, but ignores optimization of the expectation. We consider the expectation
optimization with probabilistic guarantee (EOPG) problem, where the goal is to
optimize the expectation ensuring that the payoff is above a given threshold with
at least a specified probability. We present several results on the EOPG problem,
including the first algorithm to solve it.

text: Partially observable Markov decision processes (POMDPs) are widely used in
probabilistic planning problems in which an agent interacts with an environment
using noisy and imprecise sensors. We study a setting in which the sensors are
only partially defined and the goal is to synthesize “weakest” additional sensors,
such that in the resulting POMDP, there is a small-memory policy for the agent
that almost-surely (with probability 1) satisfies a reachability objective. We
show that the problem is NP-complete, and present a symbolic algorithm by encoding
the problem into SAT instances. We illustrate trade-offs between the amount of
memory of the policy and the number of additional sensors on a simple example.
We have implemented our approach and consider three classical POMDP examples from
the literature, and show that in all the examples the number of sensors can be
significantly decreased (as compared to the existing solutions in the literature)
without increasing the complexity of the policies.

text: 'We consider planning problems for graphs, Markov decision processes (MDPs),
and games on graphs. 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 where there are
k different target sets, and the problems are as follows: (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 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 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) objective-separation results showing that for MDPs the coverage problem
is harder than the sequential target problem.'

text: 'This paper is devoted to automatic competitive analysis of real-time scheduling
algorithms for firm-deadline tasksets, where only completed tasks con- tribute
some utility to the system. Given such a taskset T , the competitive ratio of
an on-line scheduling algorithm A for T is the worst-case utility ratio of A over
the utility achieved by a clairvoyant algorithm. We leverage the theory of quantitative
graph games to address the competitive analysis and competitive synthesis problems.
For the competitive analysis case, given any taskset T and any finite-memory on-
line scheduling algorithm A , we show that the competitive ratio of A in T can
be computed in polynomial time in the size of the state space of A . Our approach
is flexible as it also provides ways to model meaningful constraints on the released
task sequences that determine the competitive ratio. We provide an experimental
study of many well-known on-line scheduling algorithms, which demonstrates the
feasibility of our competitive analysis approach that effectively replaces human
ingenuity (required Preliminary versions of this paper have appeared in Chatterjee

synthesis case, we are just given a taskset T , and the goal is to automatically
synthesize an opti- mal on-line scheduling algorithm A , i.e., one that guarantees
the largest competitive ratio possible for T . We show how the competitive synthesis
problem can be reduced to a two-player graph game with partial information, and
establish that the compu- tational complexity of solving this game is Np -complete.
The competitive synthesis problem is hence in Np in the size of the state space
of the non-deterministic labeled transition system encoding the taskset. Overall,
the proposed framework assists in the selection of suitable scheduling algorithms
for a given taskset, which is in fact the most common situation in real-time systems
design. '

text: We consider a class of students learning a language from a teacher. The situation
can be interpreted as a group of child learners receiving input from the linguistic
environment. The teacher provides sample sentences. The students try to learn
the grammar from the teacher. In addition to just listening to the teacher, the
students can also communicate with each other. The students hold hypotheses about
the grammar and change them if they receive counter evidence. The process stops
when all students have converged to the correct grammar. We study how the time
to convergence depends on the structure of the classroom by introducing and evaluating
various complexity measures. We find that structured communication between students,
although potentially introducing confusion, can greatly reduce some of the complexity
measures. Our theory can also be interpreted as applying to the scientific process,
where nature is the teacher and the scientists are the students.

text: 'Because of the intrinsic randomness of the evolutionary process, a mutant
with a fitness advantage has some chance to be selected but no certainty. Any
experiment that searches for advantageous mutants will lose many of them due to
random drift. It is therefore of great interest to find population structures
that improve the odds of advantageous mutants. Such structures are called amplifiers
of natural selection: they increase the probability that advantageous mutants
are selected. Arbitrarily strong amplifiers guarantee the selection of advantageous
mutants, even for very small fitness advantage. Despite intensive research over
the past decade, arbitrarily strong amplifiers have remained rare. Here we show
how to construct a large variety of them. Our amplifiers are so simple that they
could be useful in biotechnology, when optimizing biological molecules, or as
a diagnostic tool, when searching for faster dividing cells or viruses. They could
also occur in natural population structures.'

text: 'Crypto-currencies are digital assets designed to work as a medium of exchange,
e.g., Bitcoin, but they are susceptible to attacks (dishonest behavior of participants).
A framework for the analysis of attacks in crypto-currencies requires (a) modeling
of game-theoretic aspects to analyze incentives for deviation from honest behavior;
(b) concurrent interactions between participants; and (c) analysis of long-term
monetary gains. Traditional game-theoretic approaches for the analysis of security
protocols consider either qualitative temporal properties such as safety and termination,
or the very special class of one-shot (stateless) games. However, to analyze general
attacks on protocols for crypto-currencies, both stateful analysis and quantitative
objectives are necessary. In this work our main contributions are as follows:
(a) we show how a class of concurrent mean-payo games, namely ergodic games, can
model various attacks that arise naturally in crypto-currencies; (b) we present
the first practical implementation of algorithms for ergodic games that scales
to model realistic problems for crypto-currencies; and (c) we present experimental
results showing that our framework can handle games with thousands of states and
millions of transitions.'

text: 'Smart contracts are computer programs that are executed by a network of mutually
distrusting agents, without the need of an external trusted authority. Smart contracts
handle and transfer assets of considerable value (in the form of crypto-currency
like Bitcoin). Hence, it is crucial that their implementation is bug-free. We
identify the utility (or expected payoff) of interacting with such smart contracts
as the basic and canonical quantitative property for such contracts. We present
a framework for such quantitative analysis of smart contracts. Such a formal framework
poses new and novel research challenges in programming languages, as it requires
modeling of game-theoretic aspects to analyze incentives for deviation from honest
behavior and modeling utilities which are not specified as standard temporal properties
such as safety and termination. While game-theoretic incentives have been analyzed
in the security community, their analysis has been restricted to the very special
case of stateless games. However, to analyze smart contracts, stateful analysis
is required as it must account for the different program states of the protocol.
Our main contributions are as follows: we present (i)~a simplified programming
language for smart contracts; (ii)~an automatic translation of the programs to
state-based games; (iii)~an abstraction-refinement approach to solve such games;
and (iv)~experimental results on real-world-inspired smart contracts.'

text: We present a secure approach for maintaining andreporting credit history records on the Blockchain. Our ap-proach removes third-parties such as credit reporting agen-cies from the lending process and replaces them with smartcontracts. This allows customers to interact directly with thelenders or banks while ensuring the integrity, unmalleabilityand privacy of their credit data. Additionally, each customerhas full control over complete or selective disclosure of hercredit
records, eliminating the risk of privacy violations or databreaches. Moreover,
our approach provides strong guaranteesfor the lenders as well. A lender can check
both correctness andcompleteness of the credit data disclosed to her. This is
the firstapproach that can perform all credit reporting tasks withouta central authority or changing the financial mechanisms*.

text: "We study algorithmic questions wrt algebraic path properties in concurrent
systems, where the transitions of the system are labeled from a complete, closed
semiring. The algebraic path properties can model dataflow analysis problems,
the shortest path problem, and many other natural problems that arise in program
analysis. We consider that each component of the concurrent system is a graph
with constant treewidth, a property satisfied by the controlflow graphs of most
programs. We allow for multiple possible queries, which arise naturally in demand
driven dataflow analysis. The study of multiple queries allows us to consider
the tradeoff between the resource usage of the one-time preprocessing and for
each individual query. The traditional approach constructs the product graph of
all components and applies the best-known graph algorithm on the product. In this
approach, even the answer to a single query requires the transitive closure (i.e.,
the results of all possible queries), which provides no room for tradeoff between
preprocessing and query time.\r\nOur main contributions are algorithms that significantly
improve the worst-case running time of the traditional approach, and provide various
tradeoffs depending on the number of queries. For example, in a concurrent system
of two components, the traditional approach requires hexic time in the worst case
for answering one query as well as computing the transitive closure, whereas we
show that with one-time preprocessing in almost cubic time, each subsequent query
can be answered in at most linear time, and even the transitive closure can be
computed in almost quartic time. Furthermore, we establish conditional optimality
results showing that the worst-case running time of our algorithms cannot be improved
without achieving major breakthroughs in graph algorithms (i.e., improving the
worst-case bound for the shortest path problem in general graphs). Preliminary
experimental results show that our algorithms perform favorably on several benchmarks.\r\n"

text: 'We consider the stochastic shortest path (SSP)problem for succinct Markov
decision processes(MDPs), where the MDP consists of a set of vari-ables, and a

several ex-amples from the AI literature can be modeled assuccinct MDPs. Then
we present computationalapproaches for upper and lower bounds for theSSP problem:
(a) for computing upper bounds, ourmethod is polynomial-time in the implicit descrip-tion
of the MDP; (b) for lower bounds, we present apolynomial-time (in the size of
the implicit descrip-tion) reduction to quadratic programming. Our ap-proach is
applicable even to infinite-state MDPs.Finally, we present experimental results

text: Indirect reciprocity explores how humans act when their reputation is at stake,
and which social norms they use to assess the actions of others. A crucial question
in indirect reciprocity is which social norms can maintain stable cooperation
in a society. Past research has highlighted eight such norms, called “leading-eight”
strategies. This past research, however, is based on the assumption that all relevant
information about other population members is publicly available and that everyone
agrees on who is good or bad. Instead, here we explore the reputation dynamics
when information is private and noisy. We show that under these conditions, most
leading-eight strategies fail to evolve. Those leading-eight strategies that do
evolve are unable to sustain full cooperation.Indirect reciprocity is a mechanism
for cooperation based on shared moral systems and individual reputations. It assumes
that members of a community routinely observe and assess each other and that they
use this information to decide who is good or bad, and who deserves cooperation.
When information is transmitted publicly, such that all community members agree
on each other’s reputation, previous research has highlighted eight crucial moral
systems. These “leading-eight” strategies can maintain cooperation and resist
invasion by defectors. However, in real populations individuals often hold their
own private views of others. Once two individuals disagree about their opinion
of some third party, they may also see its subsequent actions in a different light.
Their opinions may further diverge over time. Herein, we explore indirect reciprocity
when information transmission is private and noisy. We find that in the presence
of perception errors, most leading-eight strategies cease to be stable. Even if
a leading-eight strategy evolves, cooperation rates may drop considerably when
errors are common. Our research highlights the role of reliable information and
synchronized reputations to maintain stable moral systems.

text: We present a new proof rule for proving almost-sure termination of probabilistic
programs, including those that contain demonic non-determinism. An important question
for a probabilistic program is whether the probability mass of all its diverging
runs is zero, that is that it terminates "almost surely". Proving that can be
hard, and this paper presents a new method for doing so. It applies directly to
the program's source code, even if the program contains demonic choice. Like others,
we use variant functions (a.k.a. "super-martingales") that are real-valued and
decrease randomly on each loop iteration; but our key innovation is that the amount
as well as the probability of the decrease are parametric. We prove the soundness
of the new rule, indicate where its applicability goes beyond existing rules,
and explain its connection to classical results on denumerable (non-demonic) Markov
chains.

text: The computation of the winning set for parity objectives and for Streett objectives
in graphs as well as in game graphs are central problems in computer-aided verification,
with application to the verification of closed systems with strong fairness conditions,
the verification of open systems, checking interface compatibility, well-formedness
of specifications, and the synthesis of reactive systems. We show how to compute
the winning set on n vertices for (1) parity-3 (aka one-pair Streett) objectives
in game graphs in time O(n5/2) and for (2) k-pair Streett objectives in graphs
in time O(n2+nklogn). For both problems this gives faster algorithms for dense
graphs and represents the first improvement in asymptotic running time in 15 years.

text: 'We consider Markov decision processes (MDPs) with multiple limit-average
(or mean-payoff) objectives. There exist two different views: (i) the expectation
semantics, where the goal is to optimize the expected mean-payoff objective, and
(ii) the satisfaction semantics, where the goal is to maximize the probability
of runs such that the mean-payoff value stays above a given vector. We consider
optimization with respect to both objectives at once, thus unifying the existing
semantics. Precisely, the goal is to optimize the expectation while ensuring the
satisfaction constraint. Our problem captures the notion of optimization with
respect to strategies that are risk-averse (i.e., ensure certain probabilistic
guarantee). Our main results are as follows: First, we present algorithms for
the decision problems which are always polynomial in the size of the MDP. We also
show that an approximation of the Pareto-curve can be computed in time polynomial
in the size of the MDP, and the approximation factor, but exponential in the number
of dimensions. Second, we present a complete characterization of the strategy
complexity (in terms of memory bounds and randomization) required to solve our
problem. '

text: Recently there has been a significant effort to handle quantitative properties
in formal verification and synthesis. While weighted automata over finite and
infinite words provide a natural and flexible framework to express quantitative
properties, perhaps surprisingly, some basic system properties such as average
response time cannot be expressed using weighted automata or in any other known
decidable formalism. In this work, we introduce nested weighted automata as a
natural extension of weighted automata, which makes it possible to express important
quantitative properties such as average response time. In nested weighted automata,
a master automaton spins off and collects results from weighted slave automata,
each of which computes a quantity along a finite portion of an infinite word.
Nested weighted automata can be viewed as the quantitative analogue of monitor
automata, which are used in runtime verification. We establish an almost-complete
decidability picture for the basic decision problems about nested weighted automata
and illustrate their applicability in several domains. In particular, nested weighted
automata can be used to decide average response time properties.

text: 'The edit distance between two words w 1 , w 2 is the minimal number of word
operations (letter insertions, deletions, and substitutions) necessary to transform
w 1 to w 2 . The edit distance generalizes to languages L 1 , L 2 , where the
edit distance from L 1 to L 2 is the minimal number k such that for every word
from L 1 there exists a word in L 2 with edit distance at most k . We study the
edit distance computation problem between pushdown automata and their subclasses.
The problem of computing edit distance to a pushdown automaton is undecidable,
and in practice, the interesting question is to compute the edit distance from
a pushdown automaton (the implementation, a standard model for programs with recursion)
to a regular language (the specification). In this work, we present a complete
picture of decidability and complexity for the following problems: (1) deciding
whether, for a given threshold k , the edit distance from a pushdown automaton
to a finite automaton is at most k , and (2) deciding whether the edit distance
from a pushdown automaton to a finite automaton is finite. '

text: 'The fixation probability is the probability that a new mutant introduced
in a homogeneous population eventually takes over the entire population. The fixation
probability is a fundamental quantity of natural selection, and known to depend
on the population structure. Amplifiers of natural selection are population structures
which increase the fixation probability of advantageous mutants, as compared to
the baseline case of well-mixed populations. In this work we focus on symmetric
population structures represented as undirected graphs. In the regime of undirected
graphs, the strongest amplifier known has been the Star graph, and the existence
of undirected graphs with stronger amplification properties has remained open
for over a decade. In this work we present the Comet and Comet-swarm families
of undirected graphs. We show that for a range of fitness values of the mutants,
the Comet and Cometswarm graphs have fixation probability strictly larger than
the fixation probability of the Star graph, for fixed population size and at the
limit of large populations, respectively. '

text: 'A fundamental algorithmic problem at the heart of static analysis is Dyck
reachability. The input is a graph where the edges are labeled with different
types of opening and closing parentheses, and the reachability information is
computed via paths whose parentheses are properly matched. We present new results
for Dyck reachability problems with applications to alias analysis and data-dependence
analysis. Our main contributions, that include improved upper bounds as well as
lower bounds that establish optimality guarantees, are as follows: First, we consider
Dyck reachability on bidirected graphs, which is the standard way of performing
field-sensitive points-to analysis. Given a bidirected graph with n nodes and
m edges, we present: (i) an algorithm with worst-case running time O(m + n · α(n)),
where α(n) is the inverse Ackermann function, improving the previously known O(n2)
time bound; (ii) a matching lower bound that shows that our algorithm is optimal
wrt to worst-case complexity; and (iii) an optimal average-case upper bound of
O(m) time, improving the previously known O(m · logn) bound. Second, we consider
the problem of context-sensitive data-dependence analysis, where the task is to
obtain analysis summaries of library code in the presence of callbacks. Our algorithm
preprocesses libraries in almost linear time, after which the contribution of
the library in the complexity of the client analysis is only linear, and only
wrt the number of call sites. Third, we prove that combinatorial algorithms for
Dyck reachability on general graphs with truly sub-cubic bounds cannot be obtained
without obtaining sub-cubic combinatorial algorithms for Boolean Matrix Multiplication,
which is a long-standing open problem. Thus we establish that the existing combinatorial
algorithms for Dyck reachability are (conditionally) optimal for general graphs.
We also show that the same hardness holds for graphs of constant treewidth. Finally,
we provide a prototype implementation of our algorithms for both alias analysis
and data-dependence analysis. Our experimental evaluation demonstrates that the
new algorithms significantly outperform all existing methods on the two problems,
over real-world benchmarks.'

For acyclic architectures, our algorithm is guaranteed to explore exactly one
representative trace from each observation class, while spending polynomial time
per class. Hence, our algorithm is optimal wrt the observation equivalence, and
in several cases explores exponentially fewer traces than any enumerative method
based on the Mazurkiewicz equivalence.\r\n2. For cyclic architectures, we consider
an equivalence between traces which is finer than the observation equivalence;
but coarser than the Mazurkiewicz equivalence, and in some cases is exponentially
coarser. Our data-centric DPOR algorithm remains optimal under this trace equivalence.
\r\nFinally, we perform a basic experimental comparison between the existing Mazurkiewicz-based
DPOR and our data-centric DPOR on a set of academic benchmarks. Our results show
a significant reduction in both running time and the number of explored equivalence
classes."

text: 'Evolutionary graph theory studies the evolutionary dynamics in a population
structure given as a connected graph. Each node of the graph represents an individual
of the population, and edges determine how offspring are placed. We consider the
classical birth-death Moran process where there are two types of individuals,
namely, the residents with fitness 1 and mutants with fitness r. The fitness indicates
the reproductive strength. The evolutionary dynamics happens as follows: in the
initial step, in a population of all resident individuals a mutant is introduced,
and then at each step, an individual is chosen proportional to the fitness of
its type to reproduce, and the offspring replaces a neighbor uniformly at random.
The process stops when all individuals are either residents or mutants. The probability
that all individuals in the end are mutants is called the fixation probability,
which is a key factor in the rate of evolution. We consider the problem of approximating
the fixation probability. The class of algorithms that is extremely relevant for
approximation of the fixation probabilities is the Monte-Carlo simulation of the
process. Previous results present a polynomial-time Monte-Carlo algorithm for
undirected graphs when r is given in unary. First, we present a simple modification:
instead of simulating each step, we discard ineffective steps, where no node changes
type (i.e., either residents replace residents, or mutants replace mutants). Using
the above simple modification and our result that the number of effective steps
is concentrated around the expected number of effective steps, we present faster
polynomial-time Monte-Carlo algorithms for undirected graphs. Our algorithms are
always at least a factor O(n2/ log n) faster as compared to the previous algorithms,
where n is the number of nodes, and is polynomial even if r is given in binary.
We also present lower bounds showing that the upper bound on the expected number
of effective steps we present is asymptotically tight for undirected graphs. '

text: 'Graph games provide the foundation for modeling and synthesis of reactive
processes. Such games are played over graphs where the vertices are controlled
by two adversarial players. We consider graph games where the objective of the
first player is the conjunction of a qualitative objective (specified as a parity
condition) and a quantitative objective (specified as a meanpayoff condition).
There are two variants of the problem, namely, the threshold problem where the
quantitative goal is to ensure that the mean-payoff value is above a threshold,
and the value problem where the quantitative goal is to ensure the optimal mean-payoff
value; in both cases ensuring the qualitative parity objective. The previous best-known
algorithms for game graphs with n vertices, m edges, parity objectives with d
priorities, and maximal absolute reward value W for mean-payoff objectives, are
as follows: O(nd+1 . m . w) for the threshold problem, and O(nd+2 · m · W) for
the value problem. Our main contributions are faster algorithms, and the running
times of our algorithms are as follows: O(nd-1 · m ·W) for the threshold problem,
and O(nd · m · W · log(n · W)) for the value problem. For mean-payoff parity objectives
with two priorities, our algorithms match the best-known bounds of the algorithms
for mean-payoff games (without conjunction with parity objectives). Our results
are relevant in synthesis of reactive systems with both functional requirement
(given as a qualitative objective) and performance requirement (given as a quantitative
objective).'

text: 'We consider two player, zero-sum, finite-state concurrent reachability games,
played for an infinite number of rounds, where in every round, each player simultaneously
and independently of the other players chooses an action, whereafter the successor
state is determined by a probability distribution given by the current state and
the chosen actions. Player 1 wins iff a designated goal state is eventually visited.
We are interested in the complexity of stationary strategies measured by their
patience, which is defined as the inverse of the smallest non-zero probability
employed. Our main results are as follows: We show that: (i) the optimal bound
on the patience of optimal and -optimal strategies, for both players is doubly
exponential; and (ii) even in games with a single non-absorbing state exponential
(in the number of actions) patience is necessary. '

text: In the analysis of reactive systems a quantitative objective assigns a real
value to every trace of the system. The value decision problem for a quantitative
objective requires a trace whose value is at least a given threshold, and the
exact value decision problem requires a trace whose value is exactly the threshold.
We compare the computational complexity of the value and exact value decision
problems for classical quantitative objectives, such as sum, discounted sum, energy,
and mean-payoff for two standard models of reactive systems, namely, graphs and
graph games.

text: We consider the problem of developing automated techniques for solving recurrence
relations to aid the expected-runtime analysis of programs. The motivation is
that several classical textbook algorithms have quite efficient expected-runtime
complexity, whereas the corresponding worst-case bounds are either inefficient
(e.g., Quick-Sort), or completely ineffective (e.g., Coupon-Collector). Since
the main focus of expected-runtime analysis is to obtain efficient bounds, we
consider bounds that are either logarithmic, linear or almost-linear (O(log n),
O(n), O(n · log n), respectively, where n represents the input size). Our main
contribution is an efficient (simple linear-time algorithm) sound approach for
deriving such expected-runtime bounds for the analysis of recurrence relations
induced by randomized algorithms. The experimental results show that our approach
can efficiently derive asymptotically optimal expected-runtime bounds for recurrences
of classical randomized algorithms, including Randomized-Search, Quick-Sort, Quick-Select,
Coupon-Collector, where the worst-case bounds are either inefficient (such as
linear as compared to logarithmic expected-runtime complexity, or quadratic as
compared to linear or almost-linear expected-runtime complexity), or ineffective.

text: Markov decision processes (MDPs) are standard models for probabilistic systems
with non-deterministic behaviours. Long-run average rewards provide a mathematically
elegant formalism for expressing long term performance. Value iteration (VI) is
one of the simplest and most efficient algorithmic approaches to MDPs with other
properties, such as reachability objectives. Unfortunately, a naive extension
of VI does not work for MDPs with long-run average rewards, as there is no known
stopping criterion. In this work our contributions are threefold. (1) We refute
a conjecture related to stopping criteria for MDPs with long-run average rewards.
(2) We present two practical algorithms for MDPs with long-run average rewards
based on VI. First, we show that a combination of applying VI locally for each
maximal end-component (MEC) and VI for reachability objectives can provide approximation
guarantees. Second, extending the above approach with a simulation-guided on-demand
variant of VI, we present an anytime algorithm that is able to deal with very
large models. (3) Finally, we present experimental results showing that our methods
significantly outperform the standard approaches on several benchmarks.

text: 'Graph games with omega-regular winning conditions provide a mathematical
framework to analyze a wide range of problems in the analysis of reactive systems
and programs (such as the synthesis of reactive systems, program repair, and the
verification of branching time properties). Parity conditions are canonical forms
to specify omega-regular winning conditions. Graph games with parity conditions
are equivalent to mu-calculus model checking, and thus a very important algorithmic
problem. Symbolic algorithms are of great significance because they provide scalable
algorithms for the analysis of large finite-state systems, as well as algorithms
for the analysis of infinite-state systems with finite quotient. A set-based symbolic
algorithm uses the basic set operations and the one-step predecessor operators.
We consider graph games with n vertices and parity conditions with c priorities
(equivalently, a mu-calculus formula with c alternations of least and greatest
fixed points). While many explicit algorithms exist for graph games with parity
conditions, for set-based symbolic algorithms there are only two algorithms (notice
that we use space to refer to the number of sets stored by a symbolic algorithm):
(a) the basic algorithm that requires O(n^c) symbolic operations and linear space;
and (b) an improved algorithm that requires O(n^{c/2+1}) symbolic operations but
also O(n^{c/2+1}) space (i.e., exponential space). In this work we present two
set-based symbolic algorithms for parity games: (a) our first algorithm requires
O(n^{c/2+1}) symbolic operations and only requires linear space; and (b) developing
on our first algorithm, we present an algorithm that requires O(n^{c/3+1}) symbolic
operations and only linear space. We also present the first linear space set-based
symbolic algorithm for parity games that requires at most a sub-exponential number
of symbolic operations. '

text: The extent of heterogeneity among driver gene mutations present in naturally
occurring metastases - that is, treatment-naive metastatic disease - is largely
unknown. To address this issue, we carried out 60× whole-genome sequencing of
26 metastases from four patients with pancreatic cancer. We found that identical
mutations in known driver genes were present in every metastatic lesion for each
patient studied. Passenger gene mutations, which do not have known or predicted
functional consequences, accounted for all intratumoral heterogeneity. Even with
respect to these passenger mutations, our analysis suggests that the genetic similarity
among the founding cells of metastases was higher than that expected for any two
cells randomly taken from a normal tissue. The uniformity of known driver gene
mutations among metastases in the same patient has critical and encouraging implications
for the success of future targeted therapies in advanced-stage disease.

text: Humans routinely use conditionally cooperative strategies when interacting
in repeated social dilemmas. They are more likely to cooperate if others cooperated
before, and are ready to retaliate if others defected. To capture the emergence
of reciprocity, most previous models consider subjects who can only choose from
a restricted set of representative strategies, or who react to the outcome of
the very last round only. As players memorize more rounds, the dimension of the
strategy space increases exponentially. This increasing computational complexity
renders simulations for individuals with higher cognitive abilities infeasible,
especially if multiplayer interactions are taken into account. Here, we take an
axiomatic approach instead. We propose several properties that a robust cooperative
strategy for a repeated multiplayer dilemma should have. These properties naturally
lead to a unique class of cooperative strategies, which contains the classical
Win-Stay Lose-Shift rule as a special case. A comprehensive numerical analysis
for the prisoner's dilemma and for the public goods game suggests that strategies
of this class readily evolve across various memory-n spaces. Our results reveal
that successful strategies depend not only on how cooperative others were in the
past but also on the respective context of cooperation.

text: Two-player games on graphs provide the theoretical framework for many important
problems such as reactive synthesis. While the traditional study of two-player
zero-sum games has been extended to multi-player games with several notions of
equilibria, they are decidable only for perfect-information games, whereas several
applications require imperfect-information. In this paper we propose a new notion
of equilibria, called doomsday equilibria, which is a strategy profile where all
players satisfy their own objective, and if any coalition of players deviates
and violates even one of the players' objective, then the objective of every player
is violated. We present algorithms and complexity results for deciding the existence
of doomsday equilibria for various classes of ω-regular objectives, both for imperfect-information
games, and for perfect-information games. We provide optimal complexity bounds
for imperfect-information games, and in most cases for perfect-information games.

text: We generalize winning conditions in two-player games by adding a structural
acceptance condition called obligations. Obligations are orthogonal to the linear
winning conditions that define whether a play is winning. Obligations are a declaration
that player 0 can achieve a certain value from a configuration. If the obligation
is met, the value of that configuration for player 0 is 1. We define the value
in such games and show that obligation games are determined. For Markov chains
with Borel objectives and obligations, and finite turn-based stochastic parity
games with obligations we give an alternative and simpler characterization of
the value function. Based on this simpler definition we show that the decision
problem of winning finite turn-based stochastic parity games with obligations
is in NP∩co-NP. We also show that obligation games provide a game framework for
reasoning about p-automata. © 2017 The Association for Symbolic Logic.

text: 'In antagonistic symbioses, such as host–parasite interactions, one population’s
success is the other’s loss. In mutualistic symbioses, such as division of labor,
both parties can gain, but they might have different preferences over the possible
mutualistic arrangements. The rates of evolution of the two populations in a symbiosis
are important determinants of which population will be more successful: Faster
evolution is thought to be favored in antagonistic symbioses (the “Red Queen effect”),
but disfavored in certain mutualistic symbioses (the “Red King effect”). However,
it remains unclear which biological parameters drive these effects. Here, we analyze
the effects of the various determinants of evolutionary rate: generation time,
mutation rate, population size, and the intensity of natural selection. Our main
results hold for the case where mutation is infrequent. Slower evolution causes
a long-term advantage in an important class of mutualistic interactions. Surprisingly,
less intense selection is the strongest driver of this Red King effect, whereas
relative mutation rates and generation times have little effect. In antagonistic
interactions, faster evolution by any means is beneficial. Our results provide
insight into the demographic evolution of symbionts. '

text: Nested weighted automata (NWA) present a robust and convenient automata-theoretic
formalism for quantitative specifications. Previous works have considered NWA
that processed input words only in the forward direction. It is natural to allow
the automata to process input words backwards as well, for example, to measure
the maximal or average time between a response and the preceding request. We therefore
introduce and study bidirectional NWA that can process input words in both directions.
First, we show that bidirectional NWA can express interesting quantitative properties
that are not expressible by forward-only NWA. Second, for the fundamental decision
problems of emptiness and universality, we establish decidability and complexity
results for the new framework which match the best-known results for the special
case of forward-only NWA. Thus, for NWA, the increased expressiveness of bidirectionality
is achieved at no additional computational complexity. This is in stark contrast
to the unweighted case, where bidirectional finite automata are no more expressive
but exponentially more succinct than their forward-only counterparts.

text: 'Two-player games on graphs are central in many problems in formal verification
and program analysis, such as synthesis and verification of open systems. In this
work, we consider solving recursive game graphs (or pushdown game graphs) that
model the control flow of sequential programs with recursion.While pushdown games
have been studied before with qualitative objectives-such as reachability and
?-regular objectives- in this work, we study for the first time such games with
the most well-studied quantitative objective, the mean-payoff objective. In pushdown
games, two types of strategies are relevant: (1) global strategies, which depend
on the entire global history; and (2) modular strategies, which have only local
memory and thus do not depend on the context of invocation but rather only on
the history of the current invocation of the module. Our main results are as follows:
(1) One-player pushdown games with mean-payoff objectives under global strategies
are decidable in polynomial time. (2) Two-player pushdown games with mean-payoff
objectives under global strategies are undecidable. (3) One-player pushdown games
with mean-payoff objectives under modular strategies are NP-hard. (4) Two-player
pushdown games with mean-payoff objectives under modular strategies can be solved
in NP (i.e., both one-player and two-player pushdown games with mean-payoff objectives
under modular strategies are NP-complete). We also establish the optimal strategy
complexity by showing that global strategies for mean-payoff objectives require
infinite memory even in one-player pushdown games and memoryless modular strategies
are sufficient in two-player pushdown games. Finally, we also show that all the
problems have the same complexity if the stack boundedness condition is added,
where along with the mean-payoff objective the player must also ensure that the
stack height is bounded.'

text: 'We consider finite-state and recursive game graphs with multidimensional
mean-payoff objectives. In recursive games two types of strategies are relevant:
global strategies and modular strategies. Our contributions are: (1) We show that
finite-state multidimensional mean-payoff games can be solved in polynomial time
if the number of dimensions and the maximal absolute value of weights are fixed;
whereas for arbitrary dimensions the problem is coNP-complete. (2) We show that
one-player recursive games with multidimensional mean-payoff objectives can be
solved in polynomial time. Both above algorithms are based on hyperplane separation
technique. (3) For recursive games we show that under modular strategies the multidimensional
problem is undecidable. We show that if the number of modules, exits, and the
maximal absolute value of the weights are fixed, then one-dimensional recursive
mean-payoff games under modular strategies can be solved in polynomial time, whereas
for unbounded number of exits or modules the problem is NP-hard.'

text: 'The ubiquity of computation in modern machines and devices imposes a need
to assert the correctness of their behavior. Especially in the case of safety-critical
systems, their designers need to take measures that enforce their safe operation.
Formal methods has emerged as a research field that addresses this challenge:
by rigorously proving that all system executions adhere to their specifications,
the correctness of an implementation under concern can be assured. To achieve
this goal, a plethora of techniques are nowadays available, all of which are optimized
for different system types and application domains.'

text: "Transforming deterministic ω\r\n-automata into deterministic parity automata
is traditionally done using variants of appearance records. We present a more
efficient variant of this approach, tailored to Rabin automata, and several optimizations
applicable to all appearance records. We compare the methods experimentally and
find out that our method produces smaller automata than previous approaches. Moreover,
the experiments demonstrate the potential of our method for LTL synthesis, using
LTL-to-Rabin translators. It leads to significantly smaller parity automata when
compared to state-of-the-art approaches on complex formulae."

text: "Two-player games on graphs are widely studied in formal methods as they model
the interaction between a system and its environment. The game is played by moving
a token throughout a graph to produce an infinite path. There are several common
modes to determine how the players move the token through the graph; e.g., in
turn-based games the players alternate turns in moving the token. We study the
bidding mode of moving the token, which, to the best of our knowledge, has never
been studied in infinite-duration games. Both players have separate budgets, which
sum up to $1$. In each turn, a bidding takes place. Both players submit bids simultaneously,
and a bid is legal if it does not exceed the available budget. The winner of the
bidding pays his bid to the other player and moves the token. For reachability
objectives, repeated bidding games have been studied and are called Richman games.
There, a central question is the existence and computation of threshold budgets;
namely, a value t\\in [0,1] such that if\\PO's budget exceeds $t$, he can win
the game, and if\\PT's budget exceeds 1-t, he can win the game. We focus on parity
games and mean-payoff games. We show the existence of threshold budgets in these
games, and reduce the problem of finding them to Richman games. We also determine
the strategy-complexity of an optimal strategy. Our most interesting result shows
that memoryless strategies suffice for mean-payoff bidding games. \r\n"

text: "This dissertation focuses on algorithmic aspects of program verification,
and presents modeling and complexity advances on several problems related to the\r\nstatic
analysis of programs, the stateless model checking of concurrent programs, and
the competitive analysis of real-time scheduling algorithms.\r\nOur contributions
can be broadly grouped into five categories.\r\n\r\nOur first contribution is
a set of new algorithms and data structures for the quantitative and data-flow
analysis of programs, based on the graph-theoretic notion of treewidth.\r\nIt
has been observed that the control-flow graphs of typical programs have special
structure, and are characterized as graphs of small treewidth.\r\nWe utilize this
structural property to provide faster algorithms for the quantitative and data-flow
analysis of recursive and concurrent programs.\r\nIn most cases we make an algebraic
treatment of the considered problem,\r\nwhere several interesting analyses, such
as the reachability, shortest path, and certain kind of data-flow analysis problems
follow as special cases. \r\nWe exploit the constant-treewidth property to obtain
algorithmic improvements for on-demand versions of the problems, \r\nand provide
data structures with various tradeoffs between the resources spent in the preprocessing
and querying phase.\r\nWe also improve on the algorithmic complexity of quantitative
problems outside the algebraic path framework,\r\nnamely of the minimum mean-payoff,
minimum ratio, and minimum initial credit for energy problems.\r\n\r\n\r\nOur
second contribution is a set of algorithms for Dyck reachability with applications
to data-dependence analysis and alias analysis.\r\nIn particular, we develop an
optimal algorithm for Dyck reachability on bidirected graphs, which are ubiquitous
in context-insensitive, field-sensitive points-to analysis.\r\nAdditionally, we
develop an efficient algorithm for context-sensitive data-dependence analysis
via Dyck reachability,\r\nwhere the task is to obtain analysis summaries of library
code in the presence of callbacks.\r\nOur algorithm preprocesses libraries in
almost linear time, after which the contribution of the library in the complexity
of the client analysis is (i)~linear in the number of call sites and (ii)~only
logarithmic in the size of the whole library, as opposed to linear in the size
of the whole library.\r\nFinally, we prove that Dyck reachability is Boolean Matrix
Multiplication-hard in general, and the hardness also holds for graphs of constant
treewidth.\r\nThis hardness result strongly indicates that there exist no combinatorial
algorithms for Dyck reachability with truly subcubic complexity.\r\n\r\n\r\nOur
third contribution is the formalization and algorithmic treatment of the Quantitative
Interprocedural Analysis framework.\r\nIn this framework, the transitions of a
recursive program are annotated as good, bad or neutral, and receive a weight
which measures\r\nthe magnitude of their respective effect.\r\nThe Quantitative
Interprocedural Analysis problem asks to determine whether there exists an infinite
run of the program where the long-run ratio of the bad weights over the good weights
is above a given threshold.\r\nWe illustrate how several quantitative problems
related to static analysis of recursive programs can be instantiated in this framework,\r\nand
present some case studies to this direction.\r\n\r\n\r\nOur fourth contribution
is a new dynamic partial-order reduction for the stateless model checking of concurrent
programs. Traditional approaches rely on the standard Mazurkiewicz equivalence
between traces, by means of partitioning the trace space into equivalence classes,
and attempting to explore a few representatives from each class.\r\nWe present
a new dynamic partial-order reduction method called the Data-centric Partial
Order Reduction (DC-DPOR).\r\nOur algorithm is based on a new equivalence between
traces, called the observation equivalence.\r\nDC-DPOR explores a coarser partitioning
of the trace space than any exploration method based on the standard Mazurkiewicz
equivalence.\r\nDepending on the program, the new partitioning can be even exponentially
coarser.\r\nAdditionally, DC-DPOR spends only polynomial time in each explored
class.\r\n\r\n\r\nOur fifth contribution is the use of automata and game-theoretic
verification techniques in the competitive analysis and synthesis of real-time
scheduling algorithms for firm-deadline tasks.\r\nOn the analysis side, we leverage
automata on infinite words to compute the competitive ratio of real-time schedulers
subject to various environmental constraints.\r\nOn the synthesis side, we introduce
a new instance of two-player mean-payoff partial-information games, and show\r\nhow
the synthesis of an optimal real-time scheduler can be reduced to computing winning
strategies in this new type of games."
acknowledgement: "First, I am thankful to my advisor, Krishnendu Chatterjee, for offering
me the opportunity to\r\nmaterialize my scientific curiosity in a remarkably wide
range of interesting topics, as well as for his constant availability and continuous
support throughout my doctoral studies. I have had the privilege of collaborating
with, discussing and getting inspired by all members of my committee: Thomas A.
Henzinger, Ulrich Schmid and Martin A. Nowak. The role of the above four people
has been very instrumental both to the research carried out for this dissertation,
and to the researcher I evolved to in the process.\r\nI have greatly enjoyed my
numerous brainstorming sessions with Rasmus Ibsen-Jensen, many\r\nof which led to
results on low-treewidth graphs presented here. I thank Alex Kößler for our\r\ndiscussions
on modeling and analyzing real-time scheduling algorithms, Yaron Velner for our\r\ncollaboration
on the Quantitative Interprocedural Analysis framework, and Nishant Sinha for our
initial discussions on partial order reduction techniques in stateless model checking.
I also thank Jan Otop, Ben Adlam, Bernhard Kragl and Josef Tkadlec for our fruitful
collaborations on\r\ntopics outside the scope of this dissertation, as well as the
interns Prateesh Goyal, Amir Kafshdar Goharshady, Samarth Mishra, Bhavya Choudhary
and Marek Chalupa, with whom I have shared my excitement on various research topics.

text: We consider the problem of computing the set of initial states of a dynamical
system such that there exists a control strategy to ensure that the trajectories
satisfy a temporal logic specification with probability 1 (almost-surely). We
focus on discrete-time, stochastic linear dynamics and specifications given as
formulas of the Generalized Reactivity(1) fragment of Linear Temporal Logic over
linear predicates in the states of the system. We propose a solution based on
iterative abstraction-refinement, and turn-based 2-player probabilistic games.
While the theoretical guarantee of our algorithm after any finite number of iterations
is only a partial solution, we show that if our algorithm terminates, then the
result is the set of all satisfying initial states. Moreover, for any (partial)
solution our algorithm synthesizes witness control strategies to ensure almost-sure
satisfaction of the temporal logic specification. While the proposed algorithm
guarantees progress and soundness in every iteration, it is computationally demanding.
We offer an alternative, more efficient solution for the reachability properties
that decomposes the problem into a series of smaller problems of the same type.
All algorithms are demonstrated on an illustrative case study.

text: We study controller synthesis problems for finite-state Markov decision processes,
where the objective is to optimize the expected mean-payoff performance and stability
(also known as variability in the literature). We argue that the basic notion
of expressing the stability using the statistical variance of the mean payoff
is sometimes insufficient, and propose an alternative definition. We show that
a strategy ensuring both the expected mean payoff and the variance below given
bounds requires randomization and memory, under both the above definitions. We
then show that the problem of finding such a strategy can be expressed as a set
of constraints.

text: Reconstructing the evolutionary history of metastases is critical for understanding
their basic biological principles and has profound clinical implications. Genome-wide
sequencing data has enabled modern phylogenomic methods to accurately dissect
subclones and their phylogenies from noisy and impure bulk tumour samples at unprecedented
depth. However, existing methods are not designed to infer metastatic seeding
patterns. Here we develop a tool, called Treeomics, to reconstruct the phylogeny
of metastases and map subclones to their anatomic locations. Treeomics infers
comprehensive seeding patterns for pancreatic, ovarian, and prostate cancers.
Moreover, Treeomics correctly disambiguates true seeding patterns from sequencing
artifacts; 7% of variants were misclassified by conventional statistical methods.
These artifacts can skew phylogenies by creating illusory tumour heterogeneity
among distinct samples. In silico benchmarking on simulated tumour phylogenies
across a wide range of sample purities (15–95%) and sequencing depths (25-800
× ) demonstrates the accuracy of Treeomics compared with existing methods.

text: "Simulation is an attractive alternative to language inclusion for automata
as it is an under-approximation of language inclusion, but usually has much lower
complexity. Simulation has also been extended in two orthogonal directions, namely,
(1) fair simulation, for simulation over specified set of infinite runs; and (2)
quantitative simulation, for simulation between weighted automata. While fair
trace inclusion is PSPACE-complete, fair simulation can be computed in polynomial
time. For weighted automata, the (quantitative) language inclusion problem is
undecidable in general, whereas the (quantitative) simulation reduces to quantitative
games, which admit pseudo-polynomial time algorithms.\r\n\r\nIn this work, we
study (quantitative) simulation for weighted automata with Büchi acceptance conditions,
i.e., we generalize fair simulation from non-weighted automata to weighted automata.
We show that imposing Büchi acceptance conditions on weighted automata changes
many fundamental properties of the simulation games, yet they still admit pseudo-polynomial
time algorithms."

text: Pushdown systems (PDSs) and recursive state machines (RSMs), which are linearly
equivalent, are standard models for interprocedural analysis. Yet RSMs are more
convenient as they (a) explicitly model function calls and returns, and (b) specify
many natural parameters for algorithmic analysis, e.g., the number of entries
and exits. We consider a general framework where RSM transitions are labeled from
a semiring and path properties are algebraic with semiring operations, which can
model, e.g., interprocedural reachability and dataflow analysis problems. Our
main contributions are new algorithms for several fundamental problems. As compared
to a direct translation of RSMs to PDSs and the best-known existing bounds of
PDSs, our analysis algorithm improves the complexity for finite-height semirings
(that subsumes reachability and standard dataflow properties). We further consider
the problem of extracting distance values from the representation structures computed
by our algorithm, and give efficient algorithms that distinguish the complexity
of a one-time preprocessing from the complexity of each individual query. Another
advantage of our algorithm is that our improvements carry over to the concurrent
setting, where we improve the bestknown complexity for the context-bounded analysis
of concurrent RSMs. Finally, we provide a prototype implementation that gives
a significant speed-up on several benchmarks from the SLAM/SDV project.

text: A standard objective in partially-observable Markov decision processes (POMDPs)
is to find a policy that maximizes the expected discounted-sum payoff. However,
such policies may still permit unlikely but highly undesirable outcomes, which
is problematic especially in safety-critical applications. Recently, there has
been a surge of interest in POMDPs where the goal is to maximize the probability
to ensure that the payoff is at least a given threshold, but these approaches
do not consider any optimization beyond satisfying this threshold constraint.
In this work we go beyond both the “expectation” and “threshold” approaches and
consider a “guaranteed payoff optimization (GPO)” problem for POMDPs, where we
are given a threshold t and the objective is to find a policy σ such that a) each
possible outcome of σ yields a discounted-sum payoff of at least t, and b) the
expected discounted-sum payoff of σ is optimal (or near-optimal) among all policies
satisfying a). We present a practical approach to tackle the GPO problem and evaluate
it on standard POMDP benchmarks.

text: In evolutionary game theory interactions between individuals are often assumed
obligatory. However, in many real-life situations, individuals can decide to opt
out of an interaction depending on the information they have about the opponent.
We consider a simple evolutionary game theoretic model to study such a scenario,
where at each encounter between two individuals the type of the opponent (cooperator/defector)
is known with some probability, and where each individual either accepts or opts
out of the interaction. If the type of the opponent is unknown, a trustful individual
accepts the interaction, whereas a suspicious individual opts out of the interaction.
If either of the two individuals opt out both individuals remain without an interaction.
We show that in the prisoners dilemma optional interactions along with suspicious
behaviour facilitates the emergence of trustful cooperation.

text: 'Termination is one of the basic liveness properties, and we study the termination
problem for probabilistic programs with real-valued variables. Previous works
focused on the qualitative problem that asks whether an input program terminates
with probability~1 (almost-sure termination). A powerful approach for this qualitative
problem is the notion of ranking supermartingales with respect to a given set
of invariants. The quantitative problem (probabilistic termination) asks for bounds
on the termination probability. A fundamental and conceptual drawback of the existing
approaches to address probabilistic termination is that even though the supermartingales
consider the probabilistic behavior of the programs, the invariants are obtained
completely ignoring the probabilistic aspect. In this work we address the probabilistic
termination problem for linear-arithmetic probabilistic programs with nondeterminism.
We define the notion of {\em stochastic invariants}, which are constraints along
with a probability bound that the constraints hold. We introduce a concept of
{\em repulsing supermartingales}. First, we show that repulsing supermartingales
can be used to obtain bounds on the probability of the stochastic invariants.
Second, we show the effectiveness of repulsing supermartingales in the following
three ways: (1)~With a combination of ranking and repulsing supermartingales we
can compute lower bounds on the probability of termination; (2)~repulsing supermartingales
provide witnesses for refutation of almost-sure termination; and (3)~with a combination
of ranking and repulsing supermartingales we can establish persistence properties
of probabilistic programs. We also present results on related computational problems
and an experimental evaluation of our approach on academic examples. '

text: We study the problem of developing efficient approaches for proving worst-case
bounds of non-deterministic recursive programs. Ranking functions are sound and
complete for proving termination and worst-case bounds of non-recursive programs.
First, we apply ranking functions to recursion, resulting in measure functions,
and show that they provide a sound and complete approach to prove worst-case bounds
of non-deterministic recursive programs. Our second contribution is the synthesis
of measure functions in non-polynomial forms. We show that non-polynomial measure
functions with logarithm and exponentiation can be synthesized through abstraction
of logarithmic or exponentiation terms, Farkas’ Lemma, and Handelman’s Theorem
using linear programming. While previous methods obtain worst-case polynomial
bounds, our approach can synthesize bounds of the form O(n log n) as well as O(nr)
where r is not an integer. We present experimental results to demonstrate that
our approach can efficiently obtain worst-case bounds of classical recursive algorithms
such as Merge-Sort, Closest-Pair, Karatsuba’s algorithm and Strassen’s algorithm.

text: The notion of treewidth of graphs has been exploited for faster algorithms
for several problems arising in verification and program analysis. Moreover, various
notions of balanced tree decompositions have been used for improved algorithms
supporting dynamic updates and analysis of concurrent programs. In this work,
we present a tool for constructing tree-decompositions of CFGs obtained from Java
methods, which is implemented as an extension to the widely used Soot framework.
The experimental results show that our implementation on real-world Java benchmarks
is very efficient. Our tool also provides the first implementation for balancing
tree-decompositions. In summary, we present the first tool support for exploiting
treewidth in the static analysis problems on Java programs.

text: 'Games on graphs provide the appropriate framework to study several central
problems in computer science, such as verification and synthesis of reactive systems.
One of the most basic objectives for games on graphs is the liveness (or Büchi)
objective that given a target set of vertices requires that some vertex in the
target set is visited infinitely often. We study generalized Büchi objectives
(i.e., conjunction of liveness objectives), and implications between two generalized
Büchi objectives (known as GR(1) objectives), that arise in numerous applications
in computer-aided verification. We present improved algorithms and conditional
super-linear lower bounds based on widely believed assumptions about the complexity
of (A1) combinatorial Boolean matrix multiplication and (A2) CNF-SAT. We consider
graph games with n vertices, m edges, and generalized Büchi objectives with k
conjunctions. First, we present an algorithm with running time O(k*n^2), improving
the previously known O(k*n*m) and O(k^2*n^2) worst-case bounds. Our algorithm
is optimal for dense graphs under (A1). Second, we show that the basic algorithm
for the problem is optimal for sparse graphs when the target sets have constant
size under (A2). Finally, we consider GR(1) objectives, with k_1 conjunctions
in the antecedent and k_2 conjunctions in the consequent, and present an O(k_1
k_2 n^{2.5})-time algorithm, improving the previously known O(k_1*k_2*n*m)-time
algorithm for m > n^{1.5}. '

text: "The Continuous Skolem Problem asks whether a real-valued function satisfying
a linear differen-\r\ntial equation has a zero in a given interval of real numbers.
This is a fundamental reachability\r\nproblem for continuous linear dynamical
systems, such as linear hybrid automata and continuous-\r\ntime Markov chains.
Decidability of the problem is currently open – indeed decidability is open\r\neven
for the sub-problem in which a zero is sought in a bounded interval. In this paper
we show\r\ndecidability of the bounded problem subject to Schanuel’s Conjecture,
a unifying conjecture in\r\ntranscendental number theory. We furthermore analyse
the unbounded problem in terms of the\r\nfrequencies of the differential equation,
that is, the imaginary parts of the characteristic roots.\r\nWe show that the
unbounded problem can be reduced to the bounded problem if there is at most\r\none
rationally linearly independent frequency, or if there are two rationally linearly
independent\r\nfrequencies and all characteristic roots are simple. We complete
the picture by showing that de-\r\ncidability of the unbounded problem in the
case of two (or more) rationally linearly independent\r\nfrequencies would entail
a major new effectiveness result in Diophantine approximation, namely\r\ncomputability
of the Diophantine-approximation types of all real algebraic numbers."

that express synchronization properties. A property is synchronized in a system
if it holds in all paths of a certain length. The new logic is obtained by using
the same path quantifiers and temporal operators as in CTL, but allowing a different
order of the quantifiers. This small syntactic variation induces a logic that
can express non-regular properties for which known extensions of MSO with equality
of path length are undecidable. We show that our variant of CTL is decidable and
that the model-checking problem is in Delta_3^P = P^{NP^NP}, and is DP-hard. We
analogously consider quantifier exchange in extensions of CTL, and we present
operators defined using basic operators of CTL* that express the occurrence of
infinitely many synchronization points. We show that the model-checking problem
remains in Delta_3^P. The distinguishing power of CTL and of our new logic coincide
if the Next operator is allowed in the logics, thus the classical bisimulation
quotient can be used for state-space reduction before model checking. '

text: ' While weighted automata provide a natural framework to express quantitative
properties, many basic properties like average response time cannot be expressed
with weighted automata. Nested weighted automata extend weighted automata and
consist of a master automaton and a set of slave automata that are invoked by
the master automaton. Nested weighted automata are strictly more expressive than
weighted automata (e.g., average response time can be expressed with nested weighted
automata), but the basic decision questions have higher complexity (e.g., for
deterministic automata, the emptiness question for nested weighted automata is
PSPACE-hard, whereas the corresponding complexity for weighted automata is PTIME).
We consider a natural subclass of nested weighted automata where at any point
at most a bounded number k of slave automata can be active. We focus on automata
whose master value function is the limit average. We show that these nested weighted
automata with bounded width are strictly more expressive than weighted automata
(e.g., average response time with no overlapping requests can be expressed with
bound k=1, but not with non-nested weighted automata). We show that the complexity
of the basic decision problems (i.e., emptiness and universality) for the subclass
with k constant matches the complexity for weighted automata. Moreover, when k
is part of the input given in unary we establish PSPACE-completeness.'

text: Automata with monitor counters, where the transitions do not depend on counter
values, and nested weighted automata are two expressive automata-theoretic frameworks
for quantitative properties. For a well-studied and wide class of quantitative
functions, we establish that automata with monitor counters and nested weighted
automata are equivalent. We study for the first time such quantitative automata
under probabilistic semantics. We show that several problems that are undecidable
for the classical questions of emptiness and universality become decidable under
the probabilistic semantics. We present a complete picture of decidability for
such automata, and even an almost-complete picture of computational complexity,
for the probabilistic questions we consider. © 2016 ACM.

text: 'Given a model of a system and an objective, the model-checking question asks
whether the model satisfies the objective. We study polynomial-time problems in
two classical models, graphs and Markov Decision Processes (MDPs), with respect
to several fundamental -regular objectives, e.g., Rabin and Streett objectives.
For many of these problems the best-known upper bounds are quadratic or cubic,
yet no super-linear lower bounds are known. In this work our contributions are
two-fold: First, we present several improved algorithms, and second, we present
the first conditional super-linear lower bounds based on widely believed assumptions
about the complexity of CNF-SAT and combinatorial Boolean matrix multiplication.
A separation result for two models with respect to an objective means a conditional
lower bound for one model that is strictly higher than the existing upper bound
for the other model, and similarly for two objectives with respect to a model.
Our results establish the following separation results: (1) A separation of models
(graphs and MDPs) for disjunctive queries of reachability and Büchi objectives.
(2) Two kinds of separations of objectives, both for graphs and MDPs, namely,
(2a) the separation of dual objectives such as Streett/Rabin objectives, and (2b)
the separation of conjunction and disjunction of multiple objectives of the same
type such as safety, Büchi, and coBüchi. In summary, our results establish the
first model and objective separation results for graphs and MDPs for various classical
-regular objectives. Quite strikingly, we establish conditional lower bounds for
the disjunction of objectives that are strictly higher than the existing upper
bounds for the conjunction of the same objectives. © 2016 ACM.'

text: 'Balanced knockout tournaments are ubiquitous in sports competitions and are
also used in decisionmaking and elections. The traditional computational question,
that asks to compute a draw (optimal draw) that maximizes the winning probability
for a distinguished player, has received a lot of attention. Previous works consider
the problem where the pairwise winning probabilities are known precisely, while
we study how robust is the winning probability with respect to small errors in
the pairwise winning probabilities. First, we present several illuminating examples
to establish: (a) there exist deterministic tournaments (where the pairwise winning
probabilities are 0 or 1) where one optimal draw is much more robust than the
other; and (b) in general, there exist tournaments with slightly suboptimal draws
that are more robust than all the optimal draws. The above examples motivate the
study of the computational problem of robust draws that guarantee a specified
winning probability. Second, we present a polynomial-time algorithm for approximating
the robustness of a draw for sufficiently small errors in pairwise winning probabilities,
and obtain that the stated computational problem is NP-complete. We also show
that two natural cases of deterministic tournaments where the optimal draw could
be computed in polynomial time also admit polynomial-time algorithms to compute
robust optimal draws.'

text: 'To facilitate collaboration in massive online classrooms, instructors must
make many decisions. For instance, the following parameters need to be decided
when designing a peer-feedback system where students review each others'' essays:
the number of students each student must provide feedback to, an algorithm to
map feedback providers to receivers, constraints that ensure students do not become
free-riders (receiving feedback but not providing it), the best times to receive
feedback to improve learning etc. While instructors can answer these questions
by running experiments or invoking past experience, game-theoretic models with
data from online learning platforms can identify better initial designs for further
improvements. As an example, we explore the design space of a peer feedback system
by modeling it using game theory. Our simulations show that incentivizing students
to provide feedback requires the value obtained from receiving a feedback to exceed
the cost of providing it by a large factor (greater than 7). Furthermore, hiding
feedback from low-effort students incentivizes them to provide more feedback.'

text: We study graphs and two-player games in which rewards are assigned to states,
and the goal of the players is to satisfy or dissatisfy certain property of the
generated outcome, given as a mean payoff property. Since the notion of mean-payoff
does not reflect possible fluctuations from the mean-payoff along a run, we propose
definitions and algorithms for capturing the stability of the system, and give
algorithms for deciding if a given mean payoff and stability objective can be
ensured in the system.

text: 'DEC-POMDPs extend POMDPs to a multi-agent setting, where several agents operate
in an uncertain environment independently to achieve a joint objective. DEC-POMDPs
have been studied with finite-horizon and infinite-horizon discounted-sum objectives,
and there exist solvers both for exact and approximate solutions. In this work
we consider Goal-DEC-POMDPs, where given a set of target states, the objective
is to ensure that the target set is reached with minimal cost. We consider the
indefinite-horizon (infinite-horizon with either discounted-sum, or undiscounted-sum,
where absorbing goal states have zero-cost) problem. We present a new and novel
method to solve the problem that extends methods for finite-horizon DEC-POMDPs
and the RTDP-Bel approach for POMDPs. We present experimental results on several
examples, and show that our approach presents promising results. Copyright '

text: 'We consider partially observable Markov decision processes (POMDPs) with
a set of target states and positive integer costs associated with every transition.
The traditional optimization objective (stochastic shortest path) asks to minimize
the expected total cost until the target set is reached. We extend the traditional
framework of POMDPs to model energy consumption, which represents a hard constraint.
The energy levels may increase and decrease with transitions, and the hard constraint
requires that the energy level must remain positive in all steps till the target
is reached. First, we present a novel algorithm for solving POMDPs with energy
levels, developing on existing POMDP solvers and using RTDP as its main method.
Our second contribution is related to policy representation. For larger POMDP
instances the policies computed by existing solvers are too large to be understandable.
We present an automated procedure based on machine learning techniques that automatically
extracts important decisions of the policy allowing us to compute succinct human
readable policies. Finally, we show experimentally that our algorithm performs
well and computes succinct policies on a number of POMDP instances from the literature
that were naturally enhanced with energy levels. '

processes where each transition is assigned an integer counter update and a rational
payoff. An EMDP configuration is a pair s(n), where s is a control state and n
is the current counter value. The configurations are changed by performing transitions
in the standard way. We consider the problem of computing a safe strategy (i.e.,
a strategy that keeps the counter non-negative) which maximizes the expected mean

text: Social dilemmas force players to balance between personal and collective gain.
In many dilemmas, such as elected governments negotiating climate-change mitigation
measures, the decisions are made not by individual players but by their representatives.
However, the behaviour of representatives in social dilemmas has not been investigated
experimentally. Here inspired by the negotiations for greenhouse-gas emissions
reductions, we experimentally study a collective-risk social dilemma that involves
representatives deciding on behalf of their fellow group members. Representatives
can be re-elected or voted out after each consecutive collective-risk game. Selfish
players are preferentially elected and are hence found most frequently in the
"representatives" treatment. Across all treatments, we identify the
selfish players as extortioners. As predicted by our mathematical model, their
steadfast strategies enforce cooperation from fair players who finally compensate
almost completely the deficit caused by the extortionate co-players. Everybody
gains, but the extortionate representatives and their groups gain the most.

text: In this paper we review various automata-theoretic formalisms for expressing
quantitative properties. We start with finite-state Boolean automata that express
the traditional regular properties. We then consider weighted ω-automata that
can measure the average density of events, which finite-state Boolean automata
cannot. However, even weighted ω-automata cannot express basic performance properties
like average response time. We finally consider two formalisms of weighted ω-automata
with monitors, where the monitors are either (a) counters or (b) weighted automata
themselves. We present a translation result to establish that these two formalisms
are equivalent. Weighted ω-automata with monitors generalize weighted ω-automata,
and can express average response time property. They present a natural, robust,
and expressive framework for quantitative specifications, with important decidable
properties.

text: We study repeated games with absorbing states, a type of two-player, zero-sum
concurrent mean-payoff games with the prototypical example being the Big Match
of Gillete (1957). These games may not allow optimal strategies but they always
have ε-optimal strategies. In this paper we design ε-optimal strategies for Player
1 in these games that use only O(log log T) space. Furthermore, we construct strategies
for Player 1 that use space s(T), for an arbitrary small unbounded non-decreasing
function s, and which guarantee an ε-optimal value for Player 1 in the limit superior
sense. The previously known strategies use space Ω(log T) and it was known that
no strategy can use constant space if it is ε-optimal even in the limit superior
sense. We also give a complementary lower bound. Furthermore, we also show that
no Markov strategy, even extended with finite memory, can ensure value greater
than 0 in the Big Match, answering a question posed by Neyman [11].

text: We consider higher-dimensional versions of Kannan and Lipton's Orbit Problem
- determining whether a target vector space V may be reached from a starting point
x under repeated applications of a linear transformation A. Answering two questions
posed by Kannan and Lipton in the 1980s, we show that when V has dimension one,
this problem is solvable in polynomial time, and when V has dimension two or three,
the problem is in NPRP.

text: "The continuous evolution of a wide variety of systems, including continous-time
Markov chains and linear hybrid automata, can be\r\ndescribed in terms of linear
differential equations. In this paper we study the decision problem of whether
the solution x(t) of a system of linear differential equations dx/dt = Ax reaches
a target halfspace infinitely often. This recurrent reachability problem can\r\nequivalently
be formulated as the following Infinite Zeros Problem: does a real-valued function
f:R≥0 --> R satisfying a given linear\r\ndifferential equation have infinitely
many zeros? Our main decidability result is that if the differential equation
has order at most 7, then the Infinite Zeros Problem is decidable. On the other
hand, we show that a decision procedure for the Infinite Zeros Problem at order
9 (and above) would entail a major breakthrough in Diophantine Approximation,
specifically an algorithm for computing the Lagrange constants of arbitrary real
algebraic numbers to arbitrary precision."

text: 'Brood parasites exploit their host in order to increase their own fitness.
Typically, this results in an arms race between parasite trickery and host defence.
Thus, it is puzzling to observe hosts that accept parasitism without any resistance.
The ‘mafia’ hypothesis suggests that these hosts accept parasitism to avoid retaliation.
Retaliation has been shown to evolve when the hosts condition their response to
mafia parasites, who use depredation as a targeted response to rejection. However,
it is unclear if acceptance would also emerge when ‘farming’ parasites are present
in the population. Farming parasites use depredation to synchronize the timing
with the host, destroying mature clutches to force the host to re-nest. Herein,
we develop an evolutionary model to analyse the interaction between depredatory
parasites and their hosts. We show that coevolutionary cycles between farmers
and mafia can still induce host acceptance of brood parasites. However, this equilibrium
is unstable and in the long-run the dynamics of this host–parasite interaction
exhibits strong oscillations: when farmers are the majority, accepters conditional
to mafia (the host will reject first and only accept after retaliation by the
parasite) have a higher fitness than unconditional accepters (the host always
accepts parasitism). This leads to an increase in mafia parasites’ fitness and
in turn induce an optimal environment for accepter hosts.'

text: 'Direct reciprocity is a mechanism for the evolution of cooperation based
on repeated interactions. When individuals meet repeatedly, they can use conditional
strategies to enforce cooperative outcomes that would not be feasible in one-shot
social dilemmas. Direct reciprocity requires that individuals keep track of their
past interactions and find the right response. However, there are natural bounds
on strategic complexity: Humans find it difficult to remember past interactions
accurately, especially over long timespans. Given these limitations, it is natural
to ask how complex strategies need to be for cooperation to evolve. Here, we study
stochastic evolutionary game dynamics in finite populations to systematically
compare the evolutionary performance of reactive strategies, which only respond
to the co-player''s previous move, and memory-one strategies, which take into
account the own and the co-player''s previous move. In both cases, we compare
deterministic strategy and stochastic strategy spaces. For reactive strategies
and small costs, we find that stochasticity benefits cooperation, because it allows
for generous-tit-for-tat. For memory one strategies and small costs, we find that
stochasticity does not increase the propensity for cooperation, because the deterministic
rule of win-stay, lose-shift works best. For memory one strategies and large costs,
however, stochasticity can augment cooperation.'

text: The inference of demographic history from genome data is hindered by a lack
of efficient computational approaches. In particular, it has proved difficult
to exploit the information contained in the distribution of genealogies across
the genome. We have previously shown that the generating function (GF) of genealogies
can be used to analytically compute likelihoods of demographic models from configurations
of mutations in short sequence blocks (Lohse et al. 2011). Although the GF has
a simple, recursive form, the size of such likelihood calculations explodes quickly
with the number of individuals and applications of this framework have so far
been mainly limited to small samples (pairs and triplets) for which the GF can
be written by hand. Here we investigate several strategies for exploiting the
inherent symmetries of the coalescent. In particular, we show that the GF of genealogies
can be decomposed into a set of equivalence classes that allows likelihood calculations
from nontrivial samples. Using this strategy, we automated blockwise likelihood
calculations for a general set of demographic scenarios in Mathematica. These
histories may involve population size changes, continuous migration, discrete
divergence, and admixture between multiple populations. To give a concrete example,
we calculate the likelihood for a model of isolation with migration (IM), assuming
two diploid samples without phase and outgroup information. We demonstrate the
new inference scheme with an analysis of two individual butterfly genomes from
the sister species Heliconius melpomene rosina and H. cydno.

text: 'Magic: the Gathering is a game about magical combat for any number of players.
Formally it is a zero-sum, imperfect information stochastic game that consists
of a potentially unbounded number of steps. We consider the problem of deciding
if a move is legal in a given single step of Magic. We show that the problem is
(a) coNP-complete in general; and (b) in P if either of two small sets of cards
are not used. Our lower bound holds even for single-player Magic games. The significant
aspects of our results are as follows: First, in most real-life game problems,
the task of deciding whether a given move is legal in a single step is trivial,
and the computationally hard task is to find the best sequence of legal moves
in the presence of multiple players. In contrast, quite uniquely our hardness
result holds for single step and with only one-player. Second, we establish efficient
algorithms for important special cases of Magic.'

text: Graph games provide the foundation for modeling and synthesizing reactive
processes. In the synthesis of stochastic reactive processes, the traditional
model is perfect-information stochastic games, where some transitions of the game
graph are controlled by two adversarial players, and the other transitions are
executed probabilistically. We consider such games where the objective is the
conjunction of several quantitative objectives (specified as mean-payoff conditions),
which we refer to as generalized mean-payoff objectives. The basic decision problem
asks for the existence of a finite-memory strategy for a player that ensures the
generalized mean-payoff objective be satisfied with a desired probability against
all strategies of the opponent. A special case of the decision problem is the
almost-sure problem where the desired probability is 1. Previous results presented
a semi-decision procedure for -approximations of the almost-sure problem. In this
work, we show that both the almost-sure problem as well as the general basic decision
problem are coNP-complete, significantly improving the previous results. Moreover,
we show that in the case of 1-player stochastic games, randomized memoryless strategies
are sufficient and the problem can be solved in polynomial time. In contrast,
in two-player stochastic games, we show that even with randomized strategies exponential
memory is required in general, and present a matching exponential upper bound.
We also study the basic decision problem with infinite-memory strategies and present
computational complexity results for the problem. Our results are relevant in
the synthesis of stochastic reactive systems with multiple quantitative requirements.

text: We consider partially observable Markov decision processes (POMDPs) with ω-regular
conditions specified as parity objectives. The class of ω-regular languages provides
a robust specification language to express properties in verification, and parity
objectives are canonical forms to express them. The qualitative analysis problem
given a POMDP and a parity objective asks whether there is a strategy to ensure
that the objective is satisfied with probability 1 (resp. positive probability).
While the qualitative analysis problems are undecidable even for special cases
of parity objectives, we establish decidability (with optimal complexity) for
POMDPs with all parity objectives under finite-memory strategies. We establish
optimal (exponential) memory bounds and EXPTIME-completeness of the qualitative
analysis problems under finite-memory strategies for POMDPs with parity objectives.
We also present a practical approach, where we design heuristics to deal with
the exponential complexity, and have applied our implementation on a number of
POMDP examples.
