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

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

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

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

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

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

  text: 'We introduce a general class of distances (metrics) between Markov chains,
    which are based on linear behaviour. This class encompasses distances given topologically
    (such as the total variation distance or trace distance) as well as by temporal
    logics or automata. We investigate which of the distances can be approximated
    by observing the systems, i.e. by black-box testing or simulation, and we provide
    both negative and positive results. '

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

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

  text: POMDPs are standard models for probabilistic planning problems, where an agent
    interacts with an uncertain environment. We study the problem of almost-sure reachability,
    where given a set of target states, the question is to decide whether there is
    a policy to ensure that the target set is reached with probability 1 (almost-surely).
    While in general the problem is EXPTIMEcomplete, in many practical cases policies
    with a small amount of memory suffice. Moreover, the existing solution to the
    problem is explicit, which first requires to construct explicitly an exponential
    reduction to a belief-support MDP. In this work, we first study the existence
    of observation-stationary strategies, which is NP-complete, and then small-memory
    strategies. We present a symbolic algorithm by an efficient encoding to SAT and
    using a SAT solver for the problem. We report experimental results demonstrating
    the scalability of our symbolic (SAT-based) approach. © 2016, Association for

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

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

  text: Direct reciprocity is a major mechanism for the evolution of cooperation.
    Several classical studies have suggested that humans should quickly learn to adopt
    reciprocal strategies to establish mutual cooperation in repeated interactions.
    On the other hand, the recently discovered theory of ZD strategies has found that
    subjects who use extortionate strategies are able to exploit and subdue cooperators.
    Although such extortioners have been predicted to succeed in any population of
    adaptive opponents, theoretical follow-up studies questioned whether extortion
    can evolve in reality. However, most of these studies presumed that individuals
    have similar strategic possibilities and comparable outside options, whereas asymmetries
    are ubiquitous in real world applications. Here we show with a model and an economic
    experiment that extortionate strategies readily emerge once subjects differ in
    their strategic power. Our experiment combines a repeated social dilemma with
    asymmetric partner choice. In our main treatment there is one randomly chosen
    group member who is unilaterally allowed to exchange one of the other group members
    after every ten rounds of the social dilemma. We find that this asymmetric replacement
    opportunity generally promotes cooperation, but often the resulting payoff distribution
    reflects the underlying power structure. Almost half of the subjects in a better
    strategic position turn into extortioners, who quickly proceed to exploit their
    peers. By adapting their cooperation probabilities consistent with ZD theory,
    extortioners force their co-players to cooperate without being similarly cooperative
    themselves. Comparison to non-extortionate players under the same conditions indicates
    a substantial net gain to extortion. Our results thus highlight how power asymmetries
    can endanger mutually beneficial interactions, and transform them into exploitative
    relationships. In particular, our results indicate that the extortionate strategies
    predicted from ZD theory could play a more prominent role in our daily interactions
    than previously thought.

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

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

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

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

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

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