  text: 'We consider 2-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 inde- pendently and simultaneously; the current
    state and the two moves determine the successor state. We study concurrent games
    with 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, respec- tively. In general the almost-sure
    and limit-sure winning strategies require both infinite-memory as well as infinite-precision
    (to describe probabilities). 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 power- ful as infinite-precision finite-memory strategies.
    We show that the winning sets can be computed in O(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. 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, that are obtained
    by characterization of the winning sets as μ-calculus formulas, are considerably
    more involved than those for turn-based games.'

  text: 'Turn-based stochastic games and its important subclass Markov decision processes
    (MDPs) provide models for systems with both probabilistic and nondeterministic
    behaviors. We consider turn-based stochastic games with two classical quantitative
    objectives: discounted-sum and long-run average objectives. The game models and
    the quantitative objectives are widely used in probabilistic verification, planning,
    optimal inventory control, network protocol and performance analysis. Games and
    MDPs that model realistic systems often have very large state spaces, and probabilistic
    abstraction techniques are necessary to handle the state-space explosion. The
    commonly used full-abstraction techniques do not yield space-savings for systems
    that have many states with similar value, but does not necessarily have similar
    transition structure. A semi-abstraction technique, namely Magnifying-lens abstractions
    (MLA), that clusters states based on value only, disregarding differences in their
    transition relation was proposed for qualitative objectives (reachability and
    safety objectives). In this paper we extend the MLA technique to solve stochastic
    games with discounted-sum and long-run average objectives. We present the MLA
    technique based abstraction-refinement algorithm for stochastic games and MDPs
    with discounted-sum objectives. For long-run average objectives, our solution
    works for all MDPs and a sub-class of stochastic games where every state has the
    same value. '

  text: 'We consider Markov decision processes (MDPs) with ω-regular specifications
    given as parity objectives. We consider the problem of computing the set of almost-sure
    winning states from where the objective can be ensured with probability 1. The
    algorithms for the computation of the almost-sure winning set for parity objectives
    iteratively use the solutions for the almost-sure winning set for Büchi objectives
    (a special case of parity objectives). 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(nm)  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 often have constant out-degree, and then our symbolic algorithm takes O(nn)  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(nK)  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 present faster and dynamic algorithms for the following problems arising
    in probabilistic verification: Computation of the maximal end-component (mec)

  text: 'Games played on graphs provide the mathematical framework to analyze several
    important problems in computer science as well as mathematics, such as the synthesis
    problem of Church, model checking of open reactive systems and many others. On
    the basis of mode of interaction of the players these games can be classified
    as follows: (a) turn-based (players make moves in turns); and (b) concurrent (players
    make moves simultaneously). On the basis of the information available to the players
    these games can be classified as follows: (a) perfect-information (players have
    perfect view of the game); and (b) partial-information (players have partial view
    of the game). In this talk we will consider all these classes of games with reachability
    objectives, where the goal of one player is to reach a set of target vertices
    of the graph, and the goal of the opponent player is to prevent the player from
    reaching the target. We will survey the results for various classes of games,
    and the results range from linear time decision algorithms to EXPTIME-complete
    problems to undecidable problems.'

  text: We consider Markov Decision Processes (MDPs) with mean-payoff parity and energy
    parity objectives. In system design, the parity objective is used to encode ω-regular
    specifications, and the mean-payoff and energy objectives can be used to model
    quantitative resource constraints. The energy condition re- quires that the resource
    level never drops below 0, and the mean-payoff condi- tion requires that the limit-average
    value of the resource consumption is within a threshold. While these two (energy
    and mean-payoff) classical conditions are equivalent for two-player games, we
    show that they differ for MDPs. We show that the problem of deciding whether a
    state is almost-sure winning (i.e., winning with probability 1) in energy parity
    MDPs is in NP ∩ coNP, while for mean- payoff parity MDPs, the problem is solvable
    in polynomial time, improving a recent PSPACE bound.

  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: 'Recently reported synthetic routes for the production of hollow nanoparticles
    have stimulated significant interest for the possibilities this novel geometry
    offers. While advantageous properties have been found and innovative applications
    have been proposed, the development of the full potential of these new nanostructures
    is still strongly tied to the extent of control that can be accomplished over
    their characteristics (e.g., composition, size, shell thickness, and nanocrystalline
    structure). In the present work, we investigate the means and limits of control
    over these parameters that can be obtained by the Kirkendall effect synthetic
    route on cadmium chalcogenide nanocrystalline shells. We demonstrate that the
    selection of the reactants and oxidation conditions allows some extent of control
    of the nanocrystalline structure and thickness of the shell. However, the tuning
    range is limited by the intrinsic restrictions of the synthetic procedure and
    by the dependence of the particle geometry on the same reaction conditions. Thus,
    we further explore the range of control over the shell parameters that can be
    accomplished through post-synthesis processes, such as chemical etching and thermal
    annealing. '

  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: 'Compositional theories are crucial when designing large and complex systems
    from smaller components. In this work we propose such a theory for synchronous
    concurrent systems. Our approach follows so-called interface theories, which use
    game-theoretic interpretations of composition and refinement. These are appropriate
    for systems with distinct inputs and outputs, and explicit conditions on inputs
    that must be enforced during composition. Our interfaces model systems that execute
    in an infinite sequence of synchronous rounds. At each round, a contract must
    be satisfied. The contract is simply a relation specifying the set of valid input/output
    pairs. Interfaces can be composed by parallel, serial or feedback composition.
    A refinement relation between interfaces is defined, and shown to have two main
    properties: (1) it is preserved by composition, and (2) it is equivalent to substitutability,
    namely, the ability to replace an interface by another one in any context. Shared
    refinement and abstraction operators, corresponding to greatest lower and least
    upper bounds with respect to refinement, are also defined. Input-complete interfaces,
    that impose no restrictions on inputs, and deterministic interfaces, that produce
    a unique output for any legal input, are discussed as special cases, and an interesting
    duality between the two classes is exposed. A number of illustrative examples
    are provided, as well as algorithms to compute compositions, check refinement,
    and so on, for finite-state interfaces.'

  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: Byzantine Fault Tolerant (BFT) protocols aim to improve the reliability of
    distributed systems. They enable systems to tolerate arbitrary failures in a bounded
    number of nodes. BFT protocols are usually proven correct for certain safety and
    liveness properties. However, recent studies have shown that the performance of
    state-of-the-art BFT protocols decreases drastically in the presence of even a
    single malicious node. This motivates a formal quantitative analysis of BFT protocols
    to investigate their performance characteristics under different scenarios. We
    present HyPerf, a new hybrid methodology based on model checking and simulation
    techniques for evaluating the performance of BFT protocols. We build a transition
    system corresponding to a BFT protocol and systematically explore the set of behaviors
    allowed by the protocol. We associate certain timing information with different
    operations in the protocol, like cryptographic operations and message transmission.
    After an elaborate state exploration, we use the time information to evaluate
    the performance characteristics of the protocol using simulation techniques. We
    integrate our framework in Mace, a tool for building and verifying distributed
    systems. We evaluate the performance of PBFT using our framework. We describe
    two different use-cases of our methodology. For the benign operation of the protocol,
    we use the time information as random variables to compute the probability distribution
    of the execution times. In the presence of faults, we estimate the worst-case
    performance of the protocol for various attacks that can be employed by malicious
    nodes. Our results show the importance of hybrid techniques in systematically
    analyzing the performance of large-scale systems.

  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: 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: The static scheduling problem often arises as a fundamental problem in real-time
    systems and grid computing. We consider the problem of statically scheduling a
    large job expressed as a task graph on a large number of computing nodes, such
    as a data center. This paper solves the large-scale static scheduling problem
    using abstraction refinement, a technique commonly used in formal verification
    to efficiently solve computationally hard problems. A scheduler based on abstraction
    refinement first attempts to solve the scheduling problem with abstract representations
    of the job and the computing resources. As abstract representations are generally
    small, the scheduling can be done reasonably fast. If the obtained schedule does
    not meet specified quality conditions (like data center utilization or schedule
    makespan) then the scheduler refines the job and data center abstractions and,
    again solves the scheduling problem. We develop different schedulers based on
    abstraction refinement. We implemented these schedulers and used them to schedule
    task graphs from various computing domains on simulated data centers with realistic
    topologies. We compared the speed of scheduling and the quality of the produced
    schedules with our abstraction refinement schedulers against a baseline scheduler
    that does not use any abstraction. We conclude that abstraction refinement techniques
    give a significant speed-up compared to traditional static scheduling heuristics,
    at a reasonable cost in the quality of the produced schedules. We further used
    our static schedulers in an actual system that we deployed on Amazon EC2 and compared
    it against the Hadoop dynamic scheduler for large MapReduce jobs. Our experiments
    indicate that there is great potential for static scheduling techniques.
