  text: We consider multi-player graph games with partial-observation and parity objective.
    While the decision problem for three-player games with a coalition of the first
    and second players against the third player is undecidable in general, we present
    a decidability result for partial-observation games where the first and third
    player are in a coalition against the second player, thus where the second player
    is adversarial but weaker due to partial-observation. We establish tight complexity
    bounds in the case where player 1 is less informed than player 2, namely 2-EXPTIME-completeness
    for parity objectives. The symmetric case of player 1 more informed than player
    2 is much more complicated, and we show that already in the case where player
    1 has perfect observation, memory of size non-elementary is necessary in general
    for reachability objectives, and the problem is decidable for safety and reachability
    objectives. From our results we derive new complexity results for partial-observation
    stochastic games.

  text: 'Systems should not only be correct but also robust in the sense that they
    behave reasonably in unexpected situations. This article addresses synthesis of
    robust reactive systems from temporal specifications. Existing methods allow arbitrary
    behavior if assumptions in the specification are violated. To overcome this, we
    define two robustness notions, combine them, and show how to enforce them in synthesis.
    The first notion applies to safety properties: If safety assumptions are violated
    temporarily, we require that the system recovers to normal operation with as few
    errors as possible. The second notion requires that, if liveness assumptions are
    violated, as many guarantees as possible should be fulfilled nevertheless. We
    present a synthesis procedure achieving this for the important class of GR(1)
    specifications, and establish complexity bounds. We also present an implementation
    of a special case of robustness, and show experimental results.'

  text: We present a new algorithm to construct a (generalized) deterministic Rabin
    automaton for an LTL formula φ. The automaton is the product of a master automaton
    and an array of slave automata, one for each G-subformula of φ. The slave automaton
    for G ψ is in charge of recognizing whether FG ψ holds. As opposed to standard
    determinization procedures, the states of all our automata have a clear logical
    structure, which allows for various optimizations. Our construction subsumes former
    algorithms for fragments of LTL. Experimental results show improvement in the
    sizes of the resulting automata compared to existing methods.

  text: 'In two-player finite-state stochastic games of partial observation on graphs,
    in every state of the graph, the players simultaneously choose an action, and
    their joint actions determine a probability distribution over the successor states.
    The game is played for infinitely many rounds and thus the players construct an
    infinite path in the graph. We consider 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 to 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, (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. Our main results for pure strategies are as follows:
    (1) For one-sided games with player 2 having perfect 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 almost-sure 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 and present symbolic algorithms that avoid the
    explicit exponential construction. (2) For one-sided games with player 1 having
    perfect observation we show that nonelementarymemory 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 nonelementary 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 exhibit serious
    flaws in previous results of the literature: we show a nonelementary memory lower
    bound for almost-sure winning whereas an exponential upper bound was previously
    claimed.'

    is the conjunction of a qualitative objective (specified as a parity condition)
    and a quantitative objective (specified as a mean-payoff condition). We establish
    that the problem of deciding whether the System can ensure that the probability
    to satisfy the mean-payoff parity objective is at least a given threshold is in
    NP ∩ coNP, matching the best known bound in the special case of 2-player games
    (where all transitions are deterministic). We present an algorithm running in
    time O(d·n2d·MeanGame) to compute the set of almost-sure winning states from which
    the objective can be ensured with probability 1, where n is the number of states
    of the game, d the number of priorities of the parity objective, and MeanGame
    is the complexity to compute the set of almost-sure winning states in 2 1/2-player
    mean-payoff games. Our results are useful in the synthesis of stochastic reactive
    systems with both functional requirement (given as a qualitative objective) and
    performance requirement (given as a quantitative objective). '

  text: We consider two-player partial-observation stochastic games on finitestate
    graphs where player 1 has partial observation and player 2 has perfect observation.
    The winning condition we study are ε-regular conditions specified as parity objectives.
    The qualitative-analysis problem given a partial-observation stochastic game and
    a parity objective asks whether there is a strategy to ensure that the objective
    is satisfied with probability 1 (resp. positive probability). These qualitative-analysis
    problems are known to be undecidable. However in many applications the relevant
    question is the existence of finite-memory strategies, and the qualitative-analysis
    problems under finite-memory strategies was recently shown to be decidable in
    2EXPTIME.We improve the complexity and show that the qualitative-analysis problems
    for partial-observation stochastic parity games under finite-memory strategies
    are EXPTIME-complete; and also establish optimal (exponential) memory bounds for
    finite-memory strategies required for qualitative analysis.

  text: The edit distance between two (untimed) traces is the minimum cost of a sequence
    of edit operations (insertion, deletion, or substitution) needed to transform
    one trace to the other. Edit distances have been extensively studied in the untimed
    setting, and form the basis for approximate matching of sequences in different
    domains such as coding theory, parsing, and speech recognition. In this paper,
    we lift the study of edit distances from untimed languages to the timed setting.
    We define an edit distance between timed words which incorporates both the edit
    distance between the untimed words and the absolute difference in time stamps.
    Our edit distance between two timed words is computable in polynomial time. Further,
    we show that the edit distance between a timed word and a timed language generated
    by a timed automaton, defined as the edit distance between the word and the closest
    word in the language, is PSPACE-complete. While computing the edit distance between
    two timed automata is undecidable, we show that the approximate version, where
    we decide if the edit distance between two timed automata is either less than
    a given parameter or more than δ away from the parameter, for δ &gt; 0, can be
    solved in exponential space and is EXPSPACE-hard. Our definitions and techniques
    can be generalized to the setting of hybrid systems, and analogous decidability
    results hold for rectangular automata.

  text: We study Markov decision processes (MDPs) with multiple limit-average (or
    mean-payoff) functions. We consider two different objectives, namely, expectation
    and satisfaction objectives. Given an MDP with κ limit-average functions, in the
    expectation objective the goal is to maximize the expected limit-average value,
    and in the satisfaction objective the goal is to maximize the probability of runs
    such that the limit-average value stays above a given vector. We show that under
    the expectation objective, in contrast to the case of one limit-average function,
    both randomization and memory are necessary for strategies even for ε-approximation,
    and that finite-memory randomized strategies are sufficient for achieving Pareto
    optimal values. Under the satisfaction objective, in contrast to the case of one
    limit-average function, infinite memory is necessary for strategies achieving
    a specific value (i.e. randomized finite-memory strategies are not sufficient),
    whereas memoryless randomized strategies are sufficient for ε-approximation, for
    all ε &gt; 0. We further prove that the decision problems for both expectation
    and satisfaction objectives can be solved in polynomial time and the trade-off
    curve (Pareto curve) can be ε-approximated in time polynomial in the size of the
    MDP and 1/ε, and exponential in the number of limit-average functions, for all
    ε &gt; 0. Our analysis also reveals flaws in previous work for MDPs with multiple
    mean-payoff functions under the expectation objective, corrects the flaws, and
    allows us to obtain improved results.

  text: 'Muller games are played by two players moving a token along a graph; the
    winner is determined by the set of vertices that occur infinitely often. The central
    algorithmic problem is to compute the winning regions for the players. Different
    classes and representations of Muller games lead to problems of varying computational
    complexity. One such class are parity games; these are of particular significance
    in computational complexity, as they remain one of the few combinatorial problems
    known to be in NP ∩ co-NP but not known to be in P. We show that winning regions
    for a Muller game can be determined from the alternating structure of its traps.
    To every Muller game we then associate a natural number that we call its trap
    depth; this parameter measures how complicated the trap structure is. We present
    algorithms for parity games that run in polynomial time for graphs of bounded
    trap depth, and in general run in time exponential in the trap depth. '

  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 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 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: 'First cycle games (FCG) are played on a finite graph by two players who push
    a token along the edges until a vertex is repeated, and a simple cycle is formed.
    The winner is determined by some fixed property Y of the sequence of labels of
    the edges (or nodes) forming this cycle. These games are traditionally of interest
    because of their connection with infinite-duration games such as parity and mean-payoff
    games. We study the memory requirements for winning strategies of FCGs and certain
    associated infinite duration games. We exhibit a simple FCG that is not memoryless
    determined (this corrects a mistake in Memoryless determinacy of parity and mean
    payoff games: a simple proof by Bj⋯orklund, Sandberg, Vorobyov (2004) that claims
    that FCGs for which Y is closed under cyclic permutations are memoryless determined).
    We show that θ (n)! memory (where n is the number of nodes in the graph), which
    is always sufficient, may be necessary to win some FCGs. On the other hand, we
    identify easy to check conditions on Y (i.e., Y is closed under cyclic permutations,
    and both Y and its complement are closed under concatenation) that are sufficient
    to ensure that the corresponding FCGs and their associated infinite duration games
    are memoryless determined. We demonstrate that many games considered in the literature,
    such as mean-payoff, parity, energy, etc., satisfy these conditions. On the complexity
    side, we show (for efficiently computable Y) that while solving FCGs is in PSPACE,
    solving some families of FCGs is PSPACE-hard. '

  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. The
    existence of polynomial-time algorithms has been a major open problem for decades
    and apart from pseudopolynomial algorithms there is no algorithm that solves any
    non-trivial subclass in polynomial time. In 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 worst-case instances on which 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 the graph
    structure does not necessarily help.

  text: In this work we present a flexible tool for tumor progression, which simulates
    the evolutionary dynamics of cancer. Tumor progression implements a multi-type
    branching process where the key parameters are the fitness landscape, the mutation
    rate, and the average time of cell division. The fitness of a cancer cell depends
    on the mutations it has accumulated. The input to our tool could be any fitness
    landscape, mutation rate, and cell division time, and the tool produces the growth
    dynamics and all relevant statistics.

  text: 'We study two-player zero-sum games over infinite-state graphs equipped with
    ωB and finitary conditions. Our first contribution is about the strategy complexity,
    i.e the memory required for winning strategies: we prove that over general infinite-state
    graphs, memoryless strategies are sufficient for finitary Büchi, and finite-memory
    suffices for finitary parity games. We then study pushdown games with boundedness
    conditions, with two contributions. First we prove a collapse result for pushdown
    games with ωB-conditions, implying the decidability of solving these games. Second
    we consider pushdown games with finitary parity along with stack boundedness conditions,
    and show that solving these games is EXPTIME-complete.'

  text: 'We consider the distributed synthesis problem for temporal logic specifications.
    Traditionally, the problem has been studied for LTL, and the previous results
    show that the problem is decidable iff there is no information fork in the architecture.
    We consider the problem for fragments of LTL and our main results are as follows:
    (1) We show that the problem is undecidable for architectures with information
    forks even for the fragment of LTL with temporal operators restricted to next
    and eventually. (2) For specifications restricted to globally along with non-nested
    next operators, we establish decidability (in EXPSPACE) for star architectures
    where the processes receive disjoint inputs, whereas we establish undecidability
    for architectures containing an information fork-meet structure. (3) Finally,
    we consider LTL without the next operator, and establish decidability (NEXPTIME-complete)
    for all architectures for a fragment that consists of a set of safety assumptions,
    and a set of guarantees where each guarantee is a safety, reachability, or liveness
    condition.'

  text: We consider partially observable Markov decision processes (POMDPs) with ω-regular
    conditions specified as parity objectives. The class of ω-regular languages extends
    regular languages to infinite strings and provides a robust specification language
    to express all properties used in verification, and parity objectives are canonical
    forms to express ω-regular conditions. The qualitative analysis problem given
    a POMDP and a parity objective asks whether there is a strategy to ensure that
    the objective is satis- fied with probability 1 (resp. positive probability).
    While the qualitative analysis problems are known to be undecidable even for very
    special cases of parity objectives, we establish decidability (with optimal complexity)
    of the qualitative analysis problems for POMDPs with all parity objectives under
    finite- memory strategies. We establish asymptotically optimal (exponential) memory
    bounds and EXPTIME- completeness of the qualitative analysis problems under finite-memory
    strategies for POMDPs with parity objectives.

  text: 'We consider concurrent games played by two-players on a finite state graph,
    where in every round the players simultaneously choose a move, and the current
    state along with the joint moves determine the successor state. We study the most
    fundamental objective for concurrent games, namely, mean-payoff or limit-average
    objective, where a reward is associated to every transition, and the goal of player
    1 is to maximize the long-run average of the rewards, and the objective of player
    2 is strictly the opposite (i.e., the games are zero-sum). The path constraint
    for player 1 could be qualitative, i.e., the mean-payoff is the maximal reward,
    or arbitrarily close to it; or quantitative, i.e., a given threshold between the
    minimal and maximal reward. We consider the computation of the almost-sure (resp.
    positive) winning sets, where player 1 can ensure that the path constraint is
    satisfied with probability 1 (resp. positive probability). Almost-sure winning
    with qualitative constraint exactly corresponds to the question whether there
    exists a strategy to ensure that the payoff is the maximal reward of the game.
    Our main results for qualitative path constraints are as follows: (1) we establish
    qualitative determinacy results that show for every state either player 1 has
    a strategy to ensure almost-sure (resp. positive) winning against all player-2
    strategies or player 2 has a spoiling strategy to falsify almost-sure (resp. positive)
    winning against all player-1 strategies; (2) we present optimal strategy complexity
    results that precisely characterize the classes of strategies required for almost-sure
    and positive winning for both players; and (3) we present quadratic time algorithms
    to compute the almost-sure and the positive winning sets, matching the best known
    bound of the algorithms for much simpler problems (such as reachability objectives).
    For quantitative constraints we show that a polynomial time solution for the almost-sure
    or the positive winning set would imply a solution to a long-standing open problem
    (of solving the value problem of mean-payoff games) that is not known to be in
    polynomial time.'

  text: 'We study finite-state two-player (zero-sum) concurrent mean-payoff games
    played on a graph. We focus on the important sub-class of ergodic games where
    all states are visited infinitely often with probability 1. The algorithmic study
    of ergodic games was initiated in a seminal work of Hoffman and Karp in 1966,
    but all basic complexity questions have remained unresolved. Our main results
    for ergodic games are as follows: We establish (1) an optimal exponential bound
    on the patience of stationary strategies (where patience of a distribution is
    the inverse of the smallest positive probability and represents a complexity measure
    of a stationary strategy); (2) the approximation problem lie in FNP; (3) the approximation
    problem is at least as hard as the decision problem for simple stochastic games
    (for which NP and coNP is the long-standing best known bound). We show that the
    exact value can be expressed in the existential theory of the reals, and also
    establish square-root sum hardness for a related class of games.'

  text: "The theory of graph games is the foundation for modeling and synthesizing
    reactive processes. In the synthesis of stochastic processes, we use 2-1/2-player
    games where some transitions of the game graph are controlled by two adversarial
    players, the System and the Environment, and the other transitions are determined
    probabilistically. We consider 2-1/2-player games where the objective of the System
    is the conjunction of a qualitative objective (specified as a parity condition)
    and a quantitative objective (specified as a mean-payoff condition). We establish
    that the problem of deciding whether the System can ensure that the probability
    to satisfy the mean-payoff parity objective is at least a given threshold is in
    NP ∩ coNP, matching the best known bound in the special case of 2-player games
    (where all transitions are deterministic) with only parity objectives, or with
    only mean-payoff objectives. We present an algorithm running\r\nin time O(d ·
    n^{2d}·MeanGame) to compute the set of almost-sure winning states from which the
    objective\r\ncan be ensured with probability 1, where n is the number of states
    of the game, d the number of priorities\r\nof the parity objective, and MeanGame
    is the complexity to compute the set of almost-sure winning states\r\nin 2-1/2-player
    mean-payoff games. Our results are useful in the synthesis of stochastic reactive
    systems\r\nwith both functional requirement (given as a qualitative objective)
    and performance requirement (given\r\nas a quantitative objective)."
