  text: A standard technique for solving the parameterized model checking problem
    is to reduce it to the classic model checking problem of finitely many finite-state
    systems. This work considers some of the theoretical power and limitations of
    this technique. We focus on concurrent systems in which processes communicate
    via pairwise rendezvous, as well as the special cases of disjunctive guards and
    token passing; specifications are expressed in indexed temporal logic without
    the next operator; and the underlying network topologies are generated by suitable
    Monadic Second Order Logic formulas and graph operations. First, we settle the
    exact computational complexity of the parameterized model checking problem for
    some of our concurrent systems, and establish new decidability results for others.
    Second, we consider the cases that model checking the parameterized system can
    be reduced to model checking some fixed number of processes, the number is known
    as a cutoff. We provide many cases for when such cutoffs can be computed, establish
    lower bounds on the size of such cutoffs, and identify cases where no cutoff exists.
    Third, we consider cases for which the parameterized system is equivalent to a
    single finite-state system (more precisely a Büchi word automaton), and establish
    tight bounds on the sizes of such automata.

  text: In contrast to the usual understanding of probabilistic systems as stochastic
    processes, recently these systems have also been regarded as transformers of probabilities.
    In this paper, we give a natural definition of strong bisimulation for probabilistic
    systems corresponding to this view that treats probability distributions as first-class
    citizens. Our definition applies in the same way to discrete systems as well as
    to systems with uncountable state and action spaces. Several examples demonstrate
    that our definition refines the understanding of behavioural equivalences of probabilistic
    systems. In particular, it solves a longstanding open problem concerning the representation
    of memoryless continuous time by memoryfull continuous time. Finally, we give
    algorithms for computing this bisimulation not only for finite but also for classes
    of uncountably infinite systems.

  text: 'We study two-player concurrent games on finite-state graphs played for an
    infinite number of rounds, where in each round, the two players (player 1 and
    player 2) choose their moves independently and simultaneously; the current state
    and the two moves determine the successor state. The objectives are ω-regular
    winning conditions specified as parity objectives. We consider the qualitative
    analysis problems: the computation of the almost-sure and limit-sure winning set
    of states, where player 1 can ensure to win with probability 1 and with probability
    arbitrarily close to 1, respectively. In general the almost-sure and limit-sure
    winning strategies require both infinite-memory as well as infinite-precision
    (to describe probabilities). While the qualitative analysis problem for concurrent
    parity games with infinite-memory, infinite-precision randomized strategies was
    studied before, we study the bounded-rationality problem for qualitative analysis
    of concurrent parity games, where the strategy set for player 1 is restricted
    to bounded-resource strategies. In terms of precision, strategies can be deterministic,
    uniform, finite-precision, or infinite-precision; and in terms of memory, strategies
    can be memoryless, finite-memory, or infinite-memory. We present a precise and
    complete characterization of the qualitative winning sets for all combinations
    of classes of strategies. In particular, we show that uniform memoryless strategies
    are as powerful as finite-precision infinite-memory strategies, and infinite-precision
    memoryless strategies are as powerful as infinite-precision finite-memory strategies.
    We show that the winning sets can be computed in (n2d+3) time, where n is the
    size of the game structure and 2d is the number of priorities (or colors), and
    our algorithms are symbolic. The membership problem of whether a state belongs
    to a winning set can be decided in NP ∩ coNP. Our symbolic algorithms are based
    on a characterization of the winning sets as μ-calculus formulas, however, our
    μ-calculus formulas are crucially different from the ones for concurrent parity
    games (without bounded rationality); and our memoryless witness strategy constructions
    are significantly different from the infinite-memory witness strategy constructions
    for concurrent parity games.'

  text: We consider Markov decision processes (MDPs) which are a standard model for
    probabilistic systems.We focus on qualitative properties forMDPs that can express
    that desired behaviors of the system arise almost-surely (with probability 1)
    or with positive probability. We introduce a new simulation relation to capture
    the refinement relation ofMDPs with respect to qualitative properties, and present
    discrete graph theoretic algorithms with quadratic complexity to compute the simulation
    relation.We present an automated technique for assume-guarantee style reasoning
    for compositional analysis ofMDPs with qualitative properties by giving a counterexample
    guided abstraction-refinement approach to compute our new simulation relation.
    We have implemented our algorithms and show that the compositional analysis leads
    to significant improvements.

  text: The computation of the winning set for Büchi objectives in alternating games
    on graphs is a central problem in computer-aided verification with a large number
    of applications. The long-standing best known upper bound for solving the problem
    is Õ(n ⋅ m), where n is the number of vertices and m is the number of edges in
    the graph. We are the first to break the Õ(n ⋅ m) boundary by presenting a new
    technique that reduces the running time to O(n2). This bound also leads to O(n2)-time
    algorithms for computing the set of almost-sure winning vertices for Büchi objectives
    (1) in alternating games with probabilistic transitions (improving an earlier
    bound of Õ(n ⋅ m)), (2) in concurrent graph games with constant actions (improving
    an earlier bound of O(n3)), and (3) in Markov decision processes (improving for
    m&gt;n4/3 an earlier bound of O(m ⋅ √m)). We then show how to maintain the winning
    set for Büchi objectives in alternating games under a sequence of edge insertions
    or a sequence of edge deletions in O(n) amortized time per operation. Our algorithms
    are the first dynamic algorithms for this problem. We then consider another core
    graph theoretic problem in verification of probabilistic systems, namely computing
    the maximal end-component decomposition of a graph. We present two improved static
    algorithms for the maximal end-component decomposition problem. Our first algorithm
    is an O(m ⋅ √m)-time algorithm, and our second algorithm is an O(n2)-time algorithm
    which is obtained using the same technique as for alternating Büchi games. Thus,
    we obtain an O(min &amp;lcu;m ⋅ √m,n2})-time algorithm improving the long-standing
    O(n ⋅ m) time bound. Finally, we show how to maintain the maximal end-component
    decomposition of a graph under a sequence of edge insertions or a sequence of
    edge deletions in O(n) amortized time per edge deletion, and O(m) worst-case time
    per edge insertion. Again, our algorithms are the first dynamic algorithms for
    this problem.

  text: 'We study two-player (zero-sum) concurrent mean-payoff games played on a finite-state
    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 lies in FNP; (3) the approximation problem
    is at least as hard as the decision problem for simple stochastic games (for which
    NP ∩ coNP is the long-standing best known bound). We present a variant of the
    strategy-iteration algorithm by Hoffman and Karp; show that both our algorithm
    and the classical value-iteration algorithm can approximate the value in exponential
    time; and identify a subclass where the value-iteration algorithm is a FPTAS.
    We also show that the exact value can be expressed in the existential theory of
    the reals, and establish square-root sum hardness for a related class of games.'

  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.'

  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). 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: '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: "We consider Markov decision processes (MDPs) which are a standard model for
    probabilistic systems. We focus on qualitative properties for MDPs that can express
    that desired behaviors of the system arise almost-surely (with probability 1)
    or with positive probability.\r\nWe introduce a new simulation relation to capture
    the refinement relation of MDPs with respect to qualitative properties, and present
    discrete graph theoretic algorithms with quadratic complexity to compute the simulation
    relation.\r\nWe present an automated technique for assume-guarantee style reasoning
    for compositional analysis of MDPs with qualitative properties by giving a counter-example
    guided abstraction-refinement approach to compute our new simulation relation.
    We have implemented our algorithms and show that the compositional analysis leads
    to significant improvements. "
