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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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