  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: '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: 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: 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: '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: 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: "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: "We present a new dynamic partial-order reduction method for stateless model
    checking of concurrent programs. A common approach for exploring program behaviors
    relies on enumerating the traces of the program, without storing the visited states
    (aka stateless exploration). As the number of distinct traces grows exponentially,
    dynamic partial-order reduction (DPOR) techniques have been successfully used
    to partition the space of traces into equivalence classes (Mazurkiewicz partitioning),
    with the goal of exploring only few representative traces from each class.\r\n\r\nWe
    introduce a new equivalence on traces under sequential consistency semantics,
    which we call the observation equivalence. Two traces are observationally equivalent
    if every read event observes the same write event in both traces. While the traditional
    Mazurkiewicz equivalence is control-centric, our new definition is data-centric.
    We show that our observation equivalence is coarser than the Mazurkiewicz equivalence,
    and in many cases even exponentially coarser. We devise a DPOR exploration of
    the trace space, called data-centric DPOR, based on the observation equivalence."

  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: 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: '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: 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 &gt; 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: 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: '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: 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: 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: 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.
