  text: 'In this paper, we introduce the powerful framework of graph games for the
    analysis of real-time scheduling with firm deadlines. We introduce a novel instance
    of a partial-observation game that is suitable for this purpose, and prove decidability
    of all the involved decision problems. We derive a graph game that allows the
    automated computation of the competitive ratio (along with an optimal witness
    algorithm for the competitive ratio) and establish an NP-completeness proof for
    the graph game problem. For a given on-line algorithm, we present polynomial time
    solution for computing (i) the worst-case utility; (ii) the worst-case utility
    ratio w.r.t. a clairvoyant off-line algorithm; and (iii) the competitive ratio.
    A major strength of the proposed approach lies in its flexibility w.r.t. incorporating
    additional constraints on the adversary and/or the algorithm, including limited
    maximum or average load, finiteness of periods of overload, etc., which are easily
    added by means of additional instances of standard objective functions for graph
    games. '

  text: We study synthesis of controllers for real-time systems, where the objective
    is to stay in a given safe set. The problem is solved by obtaining winning strategies
    in the setting of concurrent two player timed automaton games with safety objectives.
    To prevent a player from winning by blocking time, we restrict each player to
    strategies that ensure that the player cannot be responsible for causing a Zeno
    run. We construct winning strategies for the controller which require access only
    to (1) the system clocks (thus, controllers which require their own internal infinitely
    precise clocks are not necessary), and (2) a logarithmic (in the number of clocks)
    number of memory bits (i.e. a linear number of memory states). Precisely, we show
    that for safety objectives, a memory of size (3 + lg (| C | + 1)) bits suffices
    for winning controller strategies, where C is the set of clocks of the timed automaton
    game, significantly improving the previous known exponential memory states bound.
    We also settle the open question of whether winning region-based strategies require
    memory for safety objectives by showing with an example the necessity of memory
    for such strategies to win for safety objectives. Finally, we show that the decision
    problem of determining if there exists a receptive player-1 winning strategy for
    safety objectives is EXPTIME-complete over timed automaton games.

  text: 'We consider Markov decision processes (MDPs) with Büchi (liveness) objectives.
    We consider the problem of computing the set of almost-sure winning states from
    where the objective can be ensured with probability 1. Our contributions are as
    follows: First, we present the first subquadratic symbolic algorithm to compute
    the almost-sure winning set for MDPs with Büchi objectives; our algorithm takes
    O(n · √ m) symbolic steps as compared to the previous known algorithm that takes
    O(n 2) symbolic steps, where n is the number of states and m is the number of
    edges of the MDP. In practice MDPs have constant out-degree, and then our symbolic
    algorithm takes O(n · √ n) symbolic steps, as compared to the previous known O(n
    2) symbolic steps algorithm. Second, we present a new algorithm, namely win-lose
    algorithm, with the following two properties: (a) the algorithm iteratively computes
    subsets of the almost-sure winning set and its complement, as compared to all
    previous algorithms that discover the almost-sure winning set upon termination;
    and (b) requires O(n · √ K) symbolic steps, where K is the maximal number of edges
    of strongly connected components (scc''s) of the MDP. The win-lose algorithm requires
    symbolic computation of scc''s. Third, we improve the algorithm for symbolic scc
    computation; the previous known algorithm takes linear symbolic steps, and our
    new algorithm improves the constants associated with the linear number of steps.
    In the worst case the previous known algorithm takes 5×n symbolic steps, whereas
    our new algorithm takes 4×n symbolic steps.'

  text: 'We study the automatic synthesis of fair non-repudiation protocols, a class
    of fair exchange protocols, used for digital contract signing. First, we show
    how to specify the objectives of the participating agents and the trusted third
    party as path formulas in linear temporal logic and prove that the satisfaction
    of these objectives imply fairness; a property required of fair exchange protocols.
    We then show that weak (co-operative) co-synthesis and classical (strictly competitive)
    co-synthesis fail, whereas assume-guarantee synthesis (AGS) succeeds. We demonstrate
    the success of AGS as follows: (a) any solution of AGS is attack-free; no subset
    of participants can violate the objectives of the other participants; (b) the
    Asokan-Shoup-Waidner certified mail protocol that has known vulnerabilities is
    not a solution of AGS; (c) the Kremer-Markowitch non-repudiation protocol is a
    solution of AGS; and (d) AGS presents a new and symmetric fair non-repudiation
    protocol that is attack-free. To our knowledge this is the first application of
    synthesis to fair non-repudiation protocols, and our results show how synthesis
    can both automatically discover vulnerabilities in protocols and generate correct
    protocols. The solution to AGS can be computed efficiently as the secure equilibrium
    solution of three-player graph games. '

  text: We consider concurrent games played on graphs. At every round of a game, each
    player simultaneously and independently selects a move; the moves jointly determine
    the transition to a successor state. Two basic objectives are the safety objective
    to stay forever in a given set of states, and its dual, the reachability objective
    to reach a given set of states. First, we present a simple proof of the fact that
    in concurrent reachability games, for all ε&gt;0, memoryless ε-optimal strategies
    exist. A memoryless strategy is independent of the history of plays, and an ε-optimal
    strategy achieves the objective with probability within ε of the value of the
    game. In contrast to previous proofs of this fact, our proof is more elementary
    and more combinatorial. Second, we present a strategy-improvement (a.k.a. policy-iteration)
    algorithm for concurrent games with reachability objectives. Finally, we present
    a strategy-improvement algorithm for turn-based stochastic games (where each player
    selects moves in turns) with safety objectives. Our algorithms yield sequences
    of player-1 strategies which ensure probabilities of winning that converge monotonically
    (from below) to the value of the game. © 2012 Elsevier Inc.

  text: Tumor growth is caused by the acquisition of driver mutations, which enhance
    the net reproductive rate of cells. Driver mutations may increase cell division,
    reduce cell death, or allow cells to overcome density-limiting effects. We study
    the dynamics of tumor growth as one additional driver mutation is acquired. Our
    models are based on two-type branching processes that terminate in either tumor
    disappearance or tumor detection. In our first model, both cell types grow exponentially,
    with a faster rate for cells carrying the additional driver. We find that the
    additional driver mutation does not affect the survival probability of the lesion,
    but can substantially reduce the time to reach the detectable size if the lesion
    is slow growing. In our second model, cells lacking the additional driver cannot
    exceed a fixed carrying capacity, due to density limitations. In this case, the
    time to detection depends strongly on this carrying capacity. Our model provides
    a quantitative framework for studying tumor dynamics during different stages of
    progression. We observe that early, small lesions need additional drivers, while
    late stage metastases are only marginally affected by them. These results help
    to explain why additional driver mutations are typically not detected in fast-growing
    metastases.

  text: We focus on the realizability problem of Message Sequence Graphs (MSG), i.e.
    the problem whether a given MSG specification is correctly distributable among
    parallel components communicating via messages. This fundamental problem of MSG
    is known to be undecidable. We introduce a well motivated restricted class of
    MSG, so called controllable-choice MSG, and show that all its models are realizable
    and moreover it is decidable whether a given MSG model is a member of this class.
    In more detail, this class of MSG specifications admits a deadlock-free realization
    by overloading existing messages with additional bounded control data. We also
    show that the presented class is the largest known subclass of MSG that allows
    for deadlock-free realization.

  text: Multithreaded programs coordinate their interaction through synchronization
    primitives like mutexes and semaphores, which are managed by an OS-provided resource
    manager. We propose algorithms for the automatic construction of code-aware resource
    managers for multithreaded embedded applications. Such managers use knowledge
    about the structure and resource usage (mutex and semaphore usage) of the threads
    to guarantee deadlock freedom and progress while managing resources in an efficient
    way. Our algorithms compute managers as winning strategies in certain infinite
    games, and produce a compact code description of these strategies. We have implemented
    the algorithms in the tool Cynthesis. Given a multithreaded program in C, the
    tool produces C code implementing a code-aware resource manager. We show in experiments
    that Cynthesis produces compact resource managers within a few minutes on a set
    of embedded benchmarks with up to 6 threads. © 2012 Springer Science+Business

  text: Multi-dimensional mean-payoff and energy games provide the mathematical foundation
    for the quantitative study of reactive systems, and play a central role in the
    emerging quantitative theory of verification and synthesis. In this work, we study
    the strategy synthesis problem for games with such multi-dimensional objectives
    along with a parity condition, a canonical way to express ω-regular conditions.
    While in general, the winning strategies in such games may require infinite memory,
    for synthesis the most relevant problem is the construction of a finite-memory
    winning strategy (if one exists). Our main contributions are as follows. First,
    we show a tight exponential bound (matching upper and lower bounds) on the memory
    required for finite-memory winning strategies in both multi-dimensional mean-payoff
    and energy games along with parity objectives. This significantly improves the
    triple exponential upper bound for multi energy games (without parity) that could
    be derived from results in literature for games on VASS (vector addition systems
    with states). Second, we present an optimal symbolic and incremental algorithm
    to compute a finite-memory winning strategy (if one exists) in such games. Finally,
    we give a complete characterization of when finite memory of strategies can be
    traded off for randomness. In particular, we show that for one-dimension mean-payoff
    parity games, randomized memoryless strategies are as powerful as their pure finite-memory
    counterparts.

  text: "Energy games belong to a class of turn-based two-player infinite-duration
    games played on a weighted directed graph. It is one of the rare and intriguing
    combinatorial problems that lie in NP ∩ co−NP, but are not known to be in P. While
    the existence of polynomial-time algorithms has been a major open problem for
    decades, there is no algorithm that solves any non-trivial subclass in polynomial
    time.\r\nIn this paper, we give several results based on the weight structures
    of the graph. First, we identify a notion of penalty and present a polynomial-time
    algorithm when the penalty is large. Our algorithm is the first polynomial-time
    algorithm on a large class of weighted graphs. It includes several counter examples
    that show that many previous algorithms, such as value iteration and random facet
    algorithms, require at least sub-exponential time. Our main technique is developing
    the first non-trivial approximation algorithm and showing how to convert it to
    an exact algorithm. Moreover, we show that in a practical case in verification
    where weights are clustered around a constant number of values, the energy game
    problem can be solved in polynomial time. We also show that the problem is still
    as hard as in general when the clique-width is bounded or the graph is strongly
    ergodic, suggesting that restricting graph structures need not help."

  text: 'We consider Markov decision processes (MDPs) with specifications given as
    Büchi (liveness) objectives. We consider the problem of computing the set of almost-sure
    winning vertices from where the objective can be ensured with probability 1. We
    study for the first time the average case complexity of the classical algorithm
    for computing the set of almost-sure winning vertices for MDPs with Büchi objectives.
    Our contributions are as follows: First, we show that for MDPs with constant out-degree
    the expected number of iterations is at most logarithmic and the average case
    running time is linear (as compared to the worst case linear number of iterations
    and quadratic time complexity). Second, for the average case analysis over all
    MDPs we show that the expected number of iterations is constant and the average
    case running time is linear (again as compared to the worst case linear number
    of iterations and quadratic time complexity). Finally we also show that given
    that all MDPs are equally likely, the probability that the classical algorithm
    requires more than constant number of iterations is exponentially small.'

  text: We study evolutionary game theory in a setting where individuals learn from
    each other. We extend the traditional approach by assuming that a population contains
    individuals with different learning abilities. In particular, we explore the situation
    where individuals have different search spaces, when attempting to learn the strategies
    of others. The search space of an individual specifies the set of strategies learnable
    by that individual. The search space is genetically given and does not change
    under social evolutionary dynamics. We introduce a general framework and study
    a specific example in the context of direct reciprocity. For this example, we
    obtain the counter intuitive result that cooperation can only evolve for intermediate
    benefit-to-cost ratios, while small and large benefit-to-cost ratios favor defection.
    Our paper is a step toward making a connection between computational learning
    theory and evolutionary game dynamics.

  text: The classical (boolean) notion of refinement for behavioral interfaces of
    system components is the alternating refinement preorder. In this paper, we define
    a quantitative measure for interfaces, called interface simulation distance. It
    makes the alternating refinement preorder quantitative by, intu- itively, tolerating
    errors (while counting them) in the alternating simulation game. We show that
    the interface simulation distance satisfies the triangle inequality, that the
    distance between two interfaces does not increase under parallel composition with
    a third interface, and that the distance between two interfaces can be bounded
    from above and below by distances between abstractions of the two interfaces.
    We illustrate the framework, and the properties of the distances under composition
    of interfaces, with two case studies.

  text: The notion of delays arises naturally in many computational models, such as,
    in the design of circuits, control systems, and dataflow languages. In this work,
    we introduce automata with delay blocks (ADBs), extending finite state automata
    with variable time delay blocks, for deferring individual transition output symbols,
    in a discrete-time setting. We show that the ADB languages strictly subsume the
    regular languages, and are incomparable in expressive power to the context-free
    languages. We show that ADBs are closed under union, concatenation and Kleene
    star, and under intersection with regular languages, but not closed under complementation
    and intersection with other ADB languages. We show that the emptiness and the
    membership problems are decidable in polynomial time for ADBs, whereas the universality
    problem is undecidable. Finally we consider the linear-time model checking problem,
    i.e., whether the language of an ADB is contained in a regular language, and show
    that the model checking problem is PSPACE-complete. Copyright 2012 ACM.

  text: We introduce games with probabilistic uncertainty, a model for controller
    synthesis in which the controller observes the state through imprecise sensors
    that provide correct information about the current state with a fixed probability.
    That is, in each step, the sensors return an observed state, and given the observed
    state, there is a probability distribution (due to the estimation error) over
    the actual current state. The controller must base its decision on the observed
    state (rather than the actual current state, which it does not know). On the other
    hand, we assume that the environment can perfectly observe the current state.
    We show that controller synthesis for qualitative ω-regular objectives in our
    model can be reduced in polynomial time to standard partial-observation stochastic
    games, and vice-versa. As a consequence we establish the precise decidability
    frontier for the new class of games, and establish optimal complexity results
    for all the decidable problems.

  text: 'We consider two-player stochastic games played on finite graphs with reachability
    objectives where the first player tries to ensure a target state to be visited
    almost-surely (i.e., with probability 1), or positively (i.e., with positive probability),
    no matter the strategy of the second player. We classify such games according
    to the information and the power of randomization available to the players. On
    the basis of information, the game can be one-sided with either (a) player 1,
    or (b) player 2 having partial observation (and the other player has perfect observation),
    or two-sided with (c) both players having partial observation. On the basis of
    randomization, the players (a) may not be allowed to use randomization (pure strategies),
    or (b) may choose a probability distribution over actions but the actual random
    choice is external and not visible to the player (actions invisible), or (c) may
    use full randomization. Our main results for pure strategies are as follows. (1)
    For one-sided games with player 1 having partial observation we show that (in
    contrast to full randomized strategies) belief-based (subset-construction based)
    strategies are not sufficient, and we present an exponential upper bound on memory
    both for almostsure and positive winning strategies; we show that the problem
    of deciding the existence of almost-sure and positive winning strategies for player
    1 is EXPTIME-complete. (2) For one-sided games with player 2 having partial observation
    we show that non-elementary memory is both necessary and sufficient for both almost-sure
    and positive winning strategies. (3) We show that for the general (two-sided)
    case finite-memory strategies are sufficient for both positive and almost-sure
    winning, and at least non-elementary memory is required. We establish the equivalence
    of the almost-sure winning problems for pure strategies and for randomized strategies
    with actions invisible. Our equivalence result exhibits serious flaws in previous
    results of the literature: we show a non-elementary memory lower bound for almost-sure
    winning whereas an exponential upper bound was previously claimed.'

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

  text: 'We consider probabilistic automata on infinite words with acceptance defined
    by parity conditions. We consider three qualitative decision problems: (i) the
    positive decision problem asks whether there is a word that is accepted with positive
    probability; (ii) the almost decision problem asks whether there is a word that
    is accepted with probability 1; and (iii) the limit decision problem asks whether
    words are accepted with probability arbitrarily close to 1. We unify and generalize
    several decidability results for probabilistic automata over infinite words, and
    identify a robust (closed under union and intersection) subclass of probabilistic
    automata for which all the qualitative decision problems are decidable for parity
    conditions. We also show that if the input words are restricted to lasso shape
    (regular) words, then the positive and almost problems are decidable for all probabilistic
    automata with parity conditions. For most decidable problems we show an optimal
    PSPACE-complete complexity bound.'

  text: 'Energy parity games are infinite two-player turn-based games played on weighted
    graphs. The objective of the game combines a (qualitative) parity condition with
    the (quantitative) requirement that the sum of the weights (i.e., the level of
    energy in the game) must remain positive. Beside their own interest in the design
    and synthesis of resource-constrained omega-regular specifications, energy parity
    games provide one of the simplest model of games with combined qualitative and
    quantitative objectives. Our main results are as follows: (a) exponential memory
    is sufficient and may be necessary for winning strategies in energy parity games;
    (b) the problem of deciding the winner in energy parity games can be solved in
    NP ∩ coNP; and (c) we give an algorithm to solve energy parity by reduction to
    energy games. We also show that the problem of deciding the winner in energy parity
    games is logspace-equivalent to the problem of deciding the winner in mean-payoff
    parity games, which can thus be solved in NP ∩ coNP. As a consequence we also
    obtain a conceptually simple algorithm to solve mean-payoff parity games.'

  text: 'We consider two-player zero-sum stochastic games on graphs with ω-regular
    winning conditions specified as parity objectives. These games have applications
    in the design and control of reactive systems. We survey the complexity results
    for the problem of deciding the winner in such games, and in classes of interest
    obtained as special cases, based on the information and the power of randomization
    available to the players, on the class of objectives and on the winning mode.
    On the basis of information, these games can be classified as follows: (a) partial-observation
    (both players have partial view of the game); (b) one-sided partial-observation
    (one player has partial-observation and the other player has complete-observation);
    and (c) complete-observation (both players have complete view of the game). The
    one-sided partial-observation games have two important subclasses: the one-player
    games, known as partial-observation Markov decision processes (POMDPs), and the
    blind one-player games, known as probabilistic automata. On the basis of randomization,
    (a) the players may not be allowed to use randomization (pure strategies), or
    (b) they may choose a probability distribution over actions but the actual random
    choice is external and not visible to the player (actions invisible), or (c) they
    may use full randomization. Finally, various classes of games are obtained by
    restricting the parity objective to a reachability, safety, Büchi, or coBüchi
    condition. We also consider several winning modes, such as sure-winning (i.e.,
    all outcomes of a strategy have to satisfy the winning condition), almost-sure
    winning (i.e., winning with probability 1), limit-sure winning (i.e., winning
    with probability arbitrarily close to 1), and value-threshold winning (i.e., winning
    with probability at least ν, where ν is a given rational). '
