  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 k reward 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 single-objective case, both randomization and memory
    are necessary for strategies, and that finite-memory randomized strategies are
    sufficient. Under the satisfaction objective, in contrast to the single-objective
    case, infinite memory is necessary for strategies, and that randomized memoryless
    strategies are sufficient for epsilon-approximation, for all epsilon&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 epsilon-approximated in time polynomial in the size of the MDP and 1/epsilon,
    and exponential in the number of reward functions, for all epsilon&gt;;0. Our
    results also reveal flaws in previous work for MDPs with multiple mean-payoff
    functions under the expectation objective, correct the flaws and obtain improved
    results.

  text: 'The class of omega-regular languages provides a robust specification language
    in verification. Every omega-regular condition can be decomposed into a safety
    part and a liveness part. The liveness part ensures that something good happens
    &quot;eventually&quot;. Finitary liveness was proposed by Alur and Henzinger as
    a stronger formulation of liveness. It requires that there exists an unknown,
    fixed bound b such that something good happens within b transitions. In this work
    we consider automata with finitary acceptance conditions defined by finitary Buchi,
    parity and Streett languages. We study languages expressible by such automata:
    we give their topological complexity and present a regular-expression characterization.
    We compare the expressive power of finitary automata and give optimal algorithms
    for classical decisions questions. We show that the finitary languages are Sigma
    2-complete; we present a complete picture of the expressive power of various classes
    of automata with finitary and infinitary acceptance conditions; we show that the
    languages defined by finitary parity automata exactly characterize the star-free
    fragment of omega B-regular languages; and we show that emptiness is NLOGSPACE-complete
    and universality as well as language inclusion are PSPACE-complete for finitary
    parity and Streett automata.'

  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 linear (in the number of clocks)
    number of memory bits. Precisely, we show that for safety objectives, a memory
    of size (3 · |C|+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 bound. We also settle the open question of whether
    winning region controller strategies require memory for safety objectives by showing
    with an example the necessity of memory for region strategies to win for safety
    objectives.

  text: 'Games on graphs provide a natural model for reactive non-terminating systems.
    In such games, the interaction of two players on an arena results in an infinite
    path that describes a run of the system. Different settings are used to model
    various open systems in computer science, as for instance turn-based or concurrent
    moves, and deterministic or stochastic transitions. In this paper, we are interested
    in turn-based games, and specifically in deterministic parity games and stochastic
    reachability games (also known as simple stochastic games). We present a simple,
    direct and efficient reduction from deterministic parity games to simple stochastic
    games: it yields an arena whose size is linear up to a logarithmic factor in size
    of the original arena.'

  text: A controller for a discrete game with ω-regular objectives requires attention
    if, intuitively, it requires measuring the state and switching from the current
    control action. Minimum attention controllers are preferable in modern shared
    implementations of cyber-physical systems because they produce the least burden
    on system resources such as processor time or communication bandwidth. We give
    algorithms to compute minimum attention controllers for ω-regular objectives in
    imperfect information discrete two-player games. We show a polynomial-time reduction
    from minimum attention controller synthesis to synthesis of controllers for mean-payoff
    parity objectives in games of incomplete information. This gives an optimal EXPTIME-complete
    synthesis algorithm. We show that the minimum attention controller problem is
    decidable for infinite state systems with finite bisimulation quotients. In particular,
    the problem is decidable for timed and rectangular automata.

  text: In two-player games on graph, the players construct an infinite path through
    the game graph and get a reward computed by a payoff function over infinite paths.
    Over weighted graphs, the typical and most studied payoff functions compute the
    limit-average or the discounted sum of the rewards along the path. Besides their
    simple definition, these two payoff functions enjoy the property that memoryless
    optimal strategies always exist. In an attempt to construct other simple payoff
    functions, we define a class of payoff functions which compute an (infinite) weighted
    average of the rewards. This new class contains both the limit-average and the
    discounted sum functions, and we show that they are the only members of this class
    which induce memoryless optimal strategies, showing that there is essentially
    no other simple payoff functions.

  text: We consider two-player graph games whose objectives are request-response condition,
    i.e conjunctions of conditions of the form "if a state with property Rq is visited,
    then later a state with property Rp is visited". The winner of such games can
    be decided in EXPTIME and the problem is known to be NP-hard. In this paper, we
    close this gap by showing that this problem is, in fact, EXPTIME-complete. We
    show that the problem becomes PSPACE-complete if we only consider games played
    on DAGs, and NP-complete or PTIME-complete if there is only one player (depending
    on whether he wants to enforce or spoil the request-response condition). We also
    present near-optimal bounds on the memory needed to design winning strategies
    for each player, in each case.

  text: In this paper, we investigate the computational complexity of quantitative
    information flow (QIF) problems. Information-theoretic quantitative relaxations
    of noninterference (based on Shannon entropy)have been introduced to enable more
    fine-grained reasoning about programs in situations where limited information
    flow is acceptable. The QIF bounding problem asks whether the information flow
    in a given program is bounded by a constant $d$. Our first result is that the
    QIF bounding problem is PSPACE-complete. The QIF memoryless synthesis problem
    asks whether it is possible to resolve nondeterministic choices in a given partial
    program in such a way that in the resulting deterministic program, the quantitative
    information flow is bounded by a given constant $d$. Our second result is that
    the QIF memoryless synthesis problem is also EXPTIME-complete. The QIF memoryless
    synthesis problem generalizes to QIF general synthesis problem which does not
    impose the memoryless requirement (that is, by allowing the synthesized program
    to have more variables then the original partial program). Our third result is
    that the QIF general synthesis problem is EXPTIME-hard.

  text: We present the tool Quasy, a quantitative synthesis tool. Quasy takes qualitative
    and quantitative specifications and automatically constructs a system that satisfies
    the qualitative specification and optimizes the quantitative specification, if
    such a system exists. The user can choose between a system that satisfies and
    optimizes the specifications (a) under all possible environment behaviors or (b)
    under the most-likely environment behaviors given as a probability distribution
    on the possible input sequences. Quasy solves these two quantitative synthesis
    problems by reduction to instances of 2-player games and Markov Decision Processes
    (MDPs) with quantitative winning objectives. Quasy can also be seen as a game
    solver for quantitative games. Most notable, it can solve lexicographic mean-payoff
    games with 2 players, MDPs with mean-payoff objectives, and ergodic MDPs with
    mean-payoff parity objectives.

  text: 'We present an algorithmic method for the quantitative, performance-aware
    synthesis of concurrent programs. The input consists of a nondeterministic partial
    program and of a parametric performance model. The nondeterminism allows the programmer
    to omit which (if any) synchronization construct is used at a particular program
    location. The performance model, specified as a weighted automaton, can capture
    system architectures by assigning different costs to actions such as locking,
    context switching, and memory and cache accesses. The quantitative synthesis problem
    is to automatically resolve the nondeterminism of the partial program so that
    both correctness is guaranteed and performance is optimal. As is standard for
    shared memory concurrency, correctness is formalized &quot;specification free&quot;,
    in particular as race freedom or deadlock freedom. For worst-case (average-case)
    performance, we show that the problem can be reduced to 2-player graph games (with
    probabilistic transitions) with quantitative objectives. While we show, using
    game-theoretic methods, that the synthesis problem is Nexp-complete, we present
    an algorithmic method and an implementation that works efficiently for concurrent
    programs and performance models of practical interest. We have implemented a prototype
    tool and used it to synthesize finite-state concurrent programs that exhibit different
    programming patterns, for several performance models representing different architectures. '

  text: We consider two-player games played in real time on game structures with clocks
    where the objectives of players are described using parity conditions. The games
    are concurrent in that at each turn, both players independently propose a time
    delay and an action, and the action with the shorter delay is chosen. To prevent
    a player from winning by blocking time, we restrict each player to play strategies
    that ensure that the player cannot be responsible for causing a zeno run. First,
    we present an efficient reduction of these games to turn-based (i.e., not concurrent)
    finite-state (i.e., untimed) parity games. Our reduction improves the best known
    complexity for solving timed parity games. Moreover, the rich class of algorithms
    for classical parity games can now be applied to timed parity games. The states
    of the resulting game are based on clock regions of the original game, and the
    state space of the finite game is linear in the size of the region graph. Second,
    we consider two restricted classes of strategies for the player that represents
    the controller in a real-time synthesis problem, namely, limit-robust and bounded-robust
    winning strategies. Using a limit-robust winning strategy, the controller cannot
    choose an exact real-valued time delay but must allow for some nonzero jitter
    in each of its actions. If there is a given lower bound on the jitter, then the
    strategy is bounded-robust winning. We show that exact strategies are more powerful
    than limit-robust strategies, which are more powerful than bounded-robust winning
    strategies for any bound. For both kinds of robust strategies, we present efficient
    reductions to standard timed automaton games. These reductions provide algorithms
    for the synthesis of robust real-time controllers.

  text: There is recently a significant effort to add quantitative objectives to formal
    verification and synthesis. We introduce and investigate the extension of temporal
    logics with quantitative atomic assertions, aiming for a general and flexible
    framework for quantitative-oriented specifications. In the heart of quantitative
    objectives lies the accumulation of values along a computation. It is either the
    accumulated summation, as with the energy objectives, or the accumulated average,
    as with the mean-payoff objectives. We investigate the extension of temporal logics
    with the prefix-accumulation assertions Sum(v) ≥ c and Avg(v) ≥ c, where v is
    a numeric variable of the system, c is a constant rational number, and Sum(v)
    and Avg(v) denote the accumulated sum and average of the values of v from the
    beginning of the computation up to the current point of time. We also allow the
    path-accumulation assertions LimInfAvg(v) ≥ c and LimSupAvg(v) ≥ c, referring
    to the average value along an entire computation. We study the border of decidability
    for extensions of various temporal logics. In particular, we show that extending
    the fragment of CTL that has only the EX, EF, AX, and AG temporal modalities by
    prefix-accumulation assertions and extending LTL with path-accumulation assertions,
    result in temporal logics whose model-checking problem is decidable. The extended
    logics allow to significantly extend the currently known energy and mean-payoff
    objectives. Moreover, the prefix-accumulation assertions may be refined with "controlled-accumulation",
    allowing, for example, to specify constraints on the average waiting time between
    a request and a grant. On the negative side, we show that the fragment we point
    to is, in a sense, the maximal logic whose extension with prefix-accumulation
    assertions permits a decidable model-checking procedure. Extending a temporal
    logic that has the EG or EU modalities, and in particular CTL and LTL, makes the
    problem undecidable.

  text: There is recently a significant effort to add quantitative objectives to formal
    verification and synthesis. We introduce and investigate the extension of temporal
    logics with quantitative atomic assertions, aiming for a general and flexible
    framework for quantitative-oriented specifications. In the heart of quantitative
    objectives lies the accumulation of values along a computation. It is either the
    accumulated summation, as with the energy objectives, or the accumulated average,
    as with the mean-payoff objectives. We investigate the extension of temporal logics
    with the prefix-accumulation assertions Sum(v) ≥ c and Avg(v) ≥ c, where v is
    a numeric variable of the system, c is a constant rational number, and Sum(v)
    and Avg(v) denote the accumulated sum and average of the values of v from the
    beginning of the computation up to the current point of time. We also allow the
    path-accumulation assertions LimInfAvg(v) ≥ c and LimSupAvg(v) ≥ c, referring
    to the average value along an entire computation. We study the border of decidability
    for extensions of various temporal logics. In particular, we show that extending
    the fragment of CTL that has only the EX, EF, AX, and AG temporal modalities by
    prefix-accumulation assertions and extending LTL with path-accumulation assertions,
    result in temporal logics whose model-checking problem is decidable. The extended
    logics allow to significantly extend the currently known energy and mean-payoff
    objectives. Moreover, the prefix-accumulation assertions may be refined with “controlled-accumulation”,
    allowing, for example, to specify constraints on the average waiting time between
    a request and a grant. On the negative side, we show that the fragment we point
    to is, in a sense, the maximal logic whose extension with prefix-accumulation
    assertions permits a decidable model-checking procedure. Extending a temporal
    logic that has the EG or EU modalities, and in particular CTL and LTL, makes the
    problem undecidable.

  text: "In two-player finite-state stochastic games of partial obser- vation on graphs,
    in every state of the graph, the players simultaneously choose an action, and
    their joint actions determine a probability distri- bution 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 pos- itively (i.e., with positive probability), no matter the
    strategy of the second player.\r\n\r\nWe 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.\r\n\r\nOur main results for pure strategies
    are as follows: (1) For one-sided games with player 2 perfect observation we show
    that (in contrast to full randomized strategies) belief-based (subset-construction
    based) strate- gies are not sufficient, and present an exponential upper bound
    on mem- ory 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 algo- rithms that avoid
    the explicit exponential construction. (2) For one-sided games with player 1 perfect
    observation we show that non-elementary memory is both necessary and sufficient
    for both almost-sure and posi- tive 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 re- sult exhibit
    serious flaws in previous results in the literature: we show a non-elementary
    memory lower bound for almost-sure winning whereas an exponential upper bound
    was previously claimed."

  text: 'We consider two-player games played on a finite state space for an infinite
    number of rounds. The games are concurrent: 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. We consider ω-regular winning
    conditions specified as parity objectives. Both players are allowed to use randomization
    when choosing their moves. We study the computation of the limit-winning set of
    states, consisting of the states where the sup-inf value of the game for player
    1 is 1: in other words, a state is limit-winning if player 1 can ensure a probability
    of winning arbitrarily close to 1. We show that the limit-winning set can be computed
    in O(n2d+2) time, where n is the size of the game structure and 2d is the number
    of priorities (or colors). The membership problem of whether a state belongs to
    the limit-winning set can be decided in NP ∩ coNP. While this complexity is the
    same as for the simpler class of turn-based parity games, where in each state
    only one of the two players has a choice of moves, our algorithms are considerably
    more involved than those for turn-based games. This is because concurrent games
    do not satisfy two of the most fundamental properties of turn-based parity games.
    First, in concurrent games limit-winning strategies require randomization; and
    second, they require infinite memory.'

  text: 'Graph games of infinite length are a natural model for open reactive processes:
    one player represents the controller, trying to ensure a given specification,
    and the other represents a hostile environment. The evolution of the system depends
    on the decisions of both players, supplemented by chance. In this work, we focus
    on the notion of randomised strategy. More specifically, we show that three natural
    definitions may lead to very different results: in the most general cases, an
    almost-surely winning situation may become almost-surely losing if the player
    is only allowed to use a weaker notion of strategy. In more reasonable settings,
    translations exist, but they require infinite memory, even in simple cases. Finally,
    some traditional problems becomes undecidable for the strongest type of strategies.'

  text: "We present an algorithmic method for the synthesis of concurrent programs
    that are optimal with respect to quantitative performance measures. The input
    consists of a sequential sketch, that is, a program that does not contain synchronization
    constructs, and of a parametric performance model that assigns costs to actions
    such as locking, context switching, and idling. The quantitative synthesis problem
    is to automatically introduce synchronization constructs into the sequential sketch
    so that both correctness is guaranteed and worst-case (or average-case) performance
    is optimized. Correctness is formalized as race freedom or linearizability.\r\n\r\nWe
    show that for worst-case performance, the problem can be modeled\r\nas a 2-player
    graph game with quantitative (limit-average) objectives, and\r\nfor average-case
    performance, as a 2 1/2 -player graph game (with probabilistic transitions). In
    both cases, the optimal correct program is derived from an optimal strategy in
    the corresponding quantitative game. We prove that the respective game problems
    are computationally expensive (NP-complete), and present several techniques that
    overcome the theoretical difficulty in cases of concurrent programs of practical
    interest.\r\n\r\nWe have implemented a prototype tool and used it for the automatic
    syn- thesis of programs that access a concurrent list. For certain parameter val-
    ues, our method automatically synthesizes various classical synchronization schemes
    for implementing a concurrent list, such as fine-grained locking or a lazy algorithm.
    For other parameter values, a new, hybrid synchronization style is synthesized,
    which uses both the lazy approach and coarse-grained locks (instead of standard
    fine-grained locks). The trade-off occurs because while fine-grained locking tends
    to decrease the cost that is due to waiting for locks, it increases cache size
    requirements."

  text: The class of ω regular languages provide a robust specification language in
    verification. Every ω-regular condition can be decomposed into a safety part and
    a liveness part. The liveness part ensures that something good happens “eventually.”
    Two main strengths of the classical, infinite-limit formulation of liveness are
    robustness (independence from the granularity of transitions) and simplicity (abstraction
    of complicated time bounds). However, the classical liveness formulation suffers
    from the drawback that the time until something good happens may be unbounded.
    A stronger formulation of liveness, so-called finitary liveness, overcomes this
    drawback, while still retaining robustness and simplicity. Finitary liveness requires
    that there exists an unknown, fixed bound b such that something good happens within
    b transitions. In this work we consider the finitary parity and Streett (fairness)
    conditions. We present the topological, automata-theoretic and logical characterization
    of finitary languages defined by finitary parity and Streett conditions. We (a)
    show that the finitary parity and Streett languages are Σ2-complete; (b) present
    a complete characterization of the expressive power of various classes of automata
    with finitary and infinitary conditions (in particular we show that non-deterministic
    finitary parity and Streett automata cannot be determinized to deterministic finitary
    parity or Streett automata); and (c) show that the languages defined by non-deterministic
    finitary parity automata exactly characterize the star-free fragment of ωB-regular
    languages.
