  text: We consider the problem of computing the set of initial states of a dynamical
    system such that there exists a control strategy to ensure that the trajectories
    satisfy a temporal logic specification with probability 1 (almost-surely). We
    focus on discrete-time, stochastic linear dynamics and specifications given as
    formulas of the Generalized Reactivity(1) fragment of Linear Temporal Logic over
    linear predicates in the states of the system. We propose a solution based on
    iterative abstraction-refinement, and turn-based 2-player probabilistic games.
    While the theoretical guarantee of our algorithm after any finite number of iterations
    is only a partial solution, we show that if our algorithm terminates, then the
    result is the set of satisfying initial states. Moreover, for any (partial) solution
    our algorithm synthesizes witness control strategies to ensure almost-sure satisfaction
    of the temporal logic specification. We demonstrate our approach on an illustrative
    case study.

  text: We consider a case study of the problem of deploying an autonomous air vehicle
    in a partially observable, dynamic, indoor environment from a specification given
    as a linear temporal logic (LTL) formula over regions of interest. We model the
    motion and sensing capabilities of the vehicle as a partially observable Markov
    decision process (POMDP). We adapt recent results for solving POMDPs with parity
    objectives to generate a control policy. We also extend the existing framework
    with a policy minimization technique to obtain a better implementable policy,
    while preserving its correctness. The proposed techniques are illustrated in an
    experimental setup involving an autonomous quadrotor performing surveillance in
    a dynamic environment.

  text: "We introduce quantitative timed refinement and timed simulation (directed)
    metrics, incorporating zenoness checks, for timed systems. These metrics assign
    positive real numbers which quantify the timing mismatches between two timed systems,
    amongst non-zeno runs. We quantify timing mismatches in three ways: (1) the maximal
    timing mismatch that can arise, (2) the “steady-state” maximal timing mismatches,
    where initial transient timing mismatches are ignored; and (3) the (long-run)
    average timing mismatches amongst two systems. These three kinds of mismatches
    constitute three important types of timing differences. Our event times are the
    global times, measured from the start of the system execution, not just the time
    durations of individual steps. We present algorithms over timed automata for computing
    the three quantitative simulation distances to within any desired degree of accuracy.
    In order to compute the values of the quantitative simulation distances, we use
    a game theoretic formulation. We introduce two new kinds of objectives for two
    player games on finite-state game graphs: (1) eventual debit-sum level objectives,
    and (2) average debit-sum level objectives. We present algorithms for computing
    the optimal values for these objectives in graph games, and then use these algorithms
    to compute the values of the timed simulation distances over timed automata.\r\n"

  text: 'In mean-payoff games, the objective of the protagonist is to ensure that
    the limit average of an infinite sequence of numeric weights is nonnegative. In
    energy games, the objective is to ensure that the running sum of weights is always
    nonnegative. Multi-mean-payoff and multi-energy games replace individual weights
    by tuples, and the limit average (resp., running sum) of each coordinate must
    be (resp., remain) nonnegative. We prove finite-memory determinacy of multi-energy
    games and show inter-reducibility of multi-mean-payoff and multi-energy games
    for finite-memory strategies. We improve the computational complexity for solving
    both classes with finite-memory strategies: we prove coNP-completeness improving
    the previous known EXPSPACE bound. For memoryless strategies, we show that deciding
    the existence of a winning strategy for the protagonist is NP-complete. We present
    the first solution of multi-mean-payoff games with infinite-memory strategies:
    we show that mean-payoff-sup objectives can be decided in NP∩coNP, whereas mean-payoff-inf
    objectives are coNP-complete.'

  text: 'We present a flexible framework for the automated competitive analysis of
    on-line scheduling algorithms for firm-deadline real-time tasks based on multi-objective
    graphs: Given a task set and an on-line scheduling algorithm specified as a labeled
    transition system, along with some optional safety, liveness, and/or limit-average
    constraints for the adversary, we automatically compute the competitive ratio
    of the algorithm w.r.t. A clairvoyant scheduler. We demonstrate the flexibility
    and power of our approach by comparing the competitive ratio of several on-line
    algorithms, including Dover, that have been proposed in the past, for various
    task sets. Our experimental results reveal that none of these algorithms is universally
    optimal, in the sense that there are task sets where other schedulers provide
    better performance. Our framework is hence a very useful design tool for selecting
    optimal algorithms for a given application.'

  text: Modal transition systems (MTS) is a well-studied specification formalism of
    reactive systems supporting a step-wise refinement methodology. Despite its many
    advantages, the formalism as well as its currently known extensions are incapable
    of expressing some practically needed aspects in the refinement process like exclusive,
    conditional and persistent choices. We introduce a new model called parametric
    modal transition systems (PMTS) together with a general modal refinement notion
    that overcomes many of the limitations. We investigate the computational complexity
    of modal and thorough refinement checking on PMTS and its subclasses and provide
    a direct encoding of the modal refinement problem into quantified Boolean formulae,
    allowing us to employ state-of-the-art QBF solvers for modal refinement checking.
    The experiments we report on show that the feasibility of refinement checking
    is more influenced by the degree of nondeterminism rather than by the syntactic
    restrictions on the types of formulae allowed in the description of the PMTS.

  text: We consider mating strategies for females who search for males sequentially
    during a season of limited length. We show that the best strategy rejects a given
    male type if encountered before a time-threshold but accepts him after. For frequency-independent
    benefits, we obtain the optimal time-thresholds explicitly for both discrete and
    continuous distributions of males, and allow for mistakes being made in assessing
    the correct male type. When the benefits are indirect (genes for the offspring)
    and the population is under frequency-dependent ecological selection, the benefits
    depend on the mating strategy of other females as well. This case is particularly
    relevant to speciation models that seek to explore the stability of reproductive
    isolation by assortative mating under frequency-dependent ecological selection.
    We show that the indirect benefits are to be quantified by the reproductive values
    of couples, and describe how the evolutionarily stable time-thresholds can be
    found. We conclude with an example based on the Levene model, in which we analyze
    the evolutionarily stable assortative mating strategies and the strength of reproductive
    isolation provided by them.

  text: 'The traditional synthesis question given a specification asks for the automatic
    construction of a system that satisfies the specification, whereas often there
    exists a preference order among the different systems that satisfy the given specification.
    Under a probabilistic assumption about the possible inputs, such a preference
    order is naturally expressed by a weighted automaton, which assigns to each word
    a value, such that a system is preferred if it generates a higher expected value.
    We solve the following optimal synthesis problem: given an omega-regular specification,
    a Markov chain that describes the distribution of inputs, and a weighted automaton
    that measures how well a system satisfies the given specification under the input
    assumption, synthesize a system that optimizes the measured value. For safety
    specifications and quantitative measures that are defined by mean-payoff automata,
    the optimal synthesis problem reduces to finding a strategy in a Markov decision
    process (MDP) that is optimal for a long-run average reward objective, which can
    be achieved in polynomial time. For general omega-regular specifications along
    with mean-payoff automata, the solution rests on a new, polynomial-time algorithm
    for computing optimal strategies in MDPs with mean-payoff parity objectives. Our
    algorithm constructs optimal strategies that consist of two memoryless strategies
    and a counter. The counter is in general not bounded. To obtain a finite-state
    system, we show how to construct an ε-optimal strategy with a bounded counter,
    for all ε &gt; 0. Furthermore, we show how to decide in polynomial time if it
    is possible to construct an optimal finite-state system (i.e., a system without
    a counter) for a given specification. We have implemented our approach and the
    underlying algorithms in a tool that 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. We present
    some experimental results showing optimal systems that were automatically generated
    in this way.'

  text: 'We consider partially observable Markov decision processes (POMDPs) with
    limit-average payoff, where a reward value in the interval [0,1] is associated
    with every transition, and the payoff of an infinite path is the long-run average
    of the rewards. We consider two types of path constraints: (i) a quantitative
    constraint defines the set of paths where the payoff is at least a given threshold
    λ1ε(0,1]; and (ii) a qualitative constraint which is a special case of the quantitative
    constraint with λ1=1. We consider the computation of the almost-sure winning set,
    where the controller needs to ensure that the path constraint is satisfied with
    probability 1. Our main results for qualitative path constraints are as follows:
    (i) the problem of deciding the existence of a finite-memory controller is EXPTIME-complete;
    and (ii) the problem of deciding the existence of an infinite-memory controller
    is undecidable. For quantitative path constraints we show that the problem of
    deciding the existence of a finite-memory controller is undecidable. We also present
    a prototype implementation of our EXPTIME algorithm and experimental results on
    several examples.'

  text: We provide a framework for compositional and iterative design and verification
    of systems with quantitative information, such as rewards, time or energy. It
    is based on disjunctive modal transition systems where we allow actions to bear
    various types of quantitative information. Throughout the design process the actions
    can be further refined and the information made more precise. We show how to compute
    the results of standard operations on the systems, including the quotient (residual),
    which has not been previously considered for quantitative non-deterministic systems.
    Our quantitative framework has close connections to the modal nu-calculus and
    is compositional with respect to general notions of distances between systems
    and the standard operations.

  text: We consider two-player games played on weighted directed graphs with mean-payoff
    and total-payoff objectives, two classical quantitative objectives. While for
    single-dimensional games the complexity and memory bounds for both objectives
    coincide, we show that in contrast to multi-dimensional mean-payoff games that
    are known to be coNP-complete, multi-dimensional total-payoff games are undecidable.
    We introduce conservative approximations of these objectives, where the payoff
    is considered over a local finite window sliding along a play, instead of the
    whole play. For single dimension, we show that (i) if the window size is polynomial,
    deciding the winner takes polynomial time, and (ii) the existence of a bounded
    window can be decided in NP ∩ coNP, and is at least as hard as solving mean-payoff
    games. For multiple dimensions, we show that (i) the problem with fixed window
    size is EXPTIME-complete, and (ii) there is no primitive-recursive algorithm to
    decide the existence of a bounded window.

  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 each 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 of 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 that 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 turn-based deterministic mean-payoff
    games) that is not known to be solvable in polynomial time.'

  text: We consider the core algorithmic problems related to verification of systems
    with respect to three classical quantitative properties, namely, the mean- payoff
    property, the ratio property, and the minimum initial credit for energy property.
    The algorithmic problem given a graph and a quantitative property asks to compute
    the optimal value (the infimum value over all traces) from every node of the graph.
    We consider graphs with constant treewidth, and it is well-known that the control-flow
    graphs of most programs have constant treewidth. Let n denote the number of nodes
    of a graph, m the number of edges (for constant treewidth graphs m = O ( n ) )
    and W the largest absolute value of the weights. Our main theoretical results
    are as follows. First, for constant treewidth graphs we present an algorithm that
    approximates the mean-payoff value within a mul- tiplicative factor of ∊ in time
    O ( n · log( n/∊ )) and linear space, as compared to the classical algorithms
    that require quadratic time. Second, for the ratio property we present an algorithm
    that for constant treewidth graphs works in time O ( n · log( | a · b · n | ))
    = O ( n · log( n · W )) , when the output is a b , as compared to the previously
    best known algorithm with running time O ( n 2 · log( n · W )) . Third, for the
    minimum initial credit problem we show that (i) for general graphs the problem
    can be solved in O ( n 2 · m ) time and the associated decision problem can be
    solved in O ( n · m ) time, improving the previous known O ( n 3 · m · log( n
    · W )) and O ( n 2 · m ) bounds, respectively; and (ii) for constant treewidth
    graphs we present an algorithm that requires O ( n · log n ) time, improving the
    previous known O ( n 4 · log( n · W )) bound. We have implemented some of our
    algorithms and show that they present a significant speedup on standard benchmarks.

  text: "We consider finite-state concurrent stochastic games, played by k>=2 players
    for an infinite number of rounds, where in every round, each player simultaneously
    and independently of the other players chooses an action, whereafter the successor
    state is determined by a probability distribution given by the current state and
    the chosen actions. We consider reachability objectives that given a target set
    of states require that some state in the target set is visited, and the dual safety
    objectives that given a target set require that only states in the target set
    are visited. We are interested in the complexity of stationary strategies measured
    by their patience, which is defined as the inverse of the smallest non-zero probability
    employed.\r\n\r\n Our main results are as follows: We show that in two-player
    zero-sum concurrent stochastic games (with reachability objective for one player
    and the complementary safety objective for the other player): (i) the optimal
    bound on the patience of optimal and epsilon-optimal strategies, for both players
    is doubly exponential; and (ii) even in games with a single non-absorbing state
    exponential (in the number of actions) patience is necessary. In general we study
    the class of non-zero-sum games admitting epsilon-Nash equilibria. We show that
    if there is at least one player with reachability objective, then doubly-exponential
    patience is needed in general for epsilon-Nash equilibrium strategies, whereas
    in contrast if all players have safety objectives, then the optimal bound on patience
    for epsilon-Nash equilibrium strategies is only exponential."

  text: "Evolution occurs in populations of reproducing individuals. The structure
    of the population affects the outcome of the evolutionary process. Evolutionary
    graph theory is a powerful approach to study this phenomenon. There are two graphs.
    The interaction graph specifies who interacts with whom in the context of evolution.The
    replacement graph specifies who competes with whom for reproduction. \r\nThe vertices
    of the two graphs are the same, and each vertex corresponds to an individual of
    the population. A key quantity is the fixation probability of a new mutant. It
    is defined as the probability that a newly introduced mutant (on a single vertex)
    generates a lineage of offspring which eventually takes over the entire population
    of resident individuals. The basic computational questions are as follows: (i)
    the qualitative question asks whether the fixation probability is positive; and
    (ii) the quantitative approximation question asks for an approximation of the
    fixation probability. \r\nOur main results are:\r\n(1) We show that the qualitative
    question is NP-complete and the quantitative approximation question is #P-hard
    in the special case when the interaction and the replacement graphs coincide and
    even with the restriction that the resident individuals do not reproduce (which
    corresponds to an invading population taking over an empty structure).\r\n(2)
    We show that in general the qualitative question is PSPACE-complete and the quantitative
    approximation question is PSPACE-hard and can be solved in exponential time.\r\n"

  text: 'Evolution occurs in populations of reproducing individuals. The structure
    of the population affects the outcome of the evolutionary process. Evolutionary
    graph theory is a powerful approach to study this phenomenon. There are two graphs.
    The interaction graph specifies who interacts with whom for payoff in the context
    of evolution. The replacement graph specifies who competes with whom for reproduction.
    The vertices of the two graphs are the same, and each vertex corresponds to an
    individual of the population. The fitness (or the reproductive rate) is a non-negative
    number, and depends on the payoff. A key quantity is the fixation probability
    of a new mutant. It is defined as the probability that a newly introduced mutant
    (on a single vertex) generates a lineage of offspring which eventually takes over
    the entire population of resident individuals. The basic computational questions
    are as follows: (i) the qualitative question asks whether the fixation probability
    is positive; and (ii) the quantitative approximation question asks for an approximation
    of the fixation probability. Our main results are as follows: First, we consider
    a special case of the general problem, where the residents do not reproduce. We
    show that the qualitative question is NP-complete, and the quantitative approximation
    question is #P-complete, and the hardness results hold even in the special case
    where the interaction and the replacement graphs coincide. Second, we show that
    in general both the qualitative and the quantitative approximation questions are
    PSPACE-complete. The PSPACE-hardness result for quantitative approximation holds
    even when the fitness is always positive.'

  text: We study algorithmic questions for concurrent systems where the transitions
    are labeled from a complete, closed semiring, and path properties are algebraic
    with semiring operations. The algebraic path properties can model dataflow analysis
    problems, the shortest path problem, and many other natural problems that arise
    in program analysis. We consider that each component of the concurrent system
    is a graph with constant treewidth, a property satisfied by the controlflow graphs
    of most programs. We allow for multiple possible queries, which arise naturally
    in demand driven dataflow analysis. The study of multiple queries allows us to
    consider the tradeoff between the resource usage of the one-time preprocessing
    and for each individual query. The traditional approach constructs the product
    graph of all components and applies the best-known graph algorithm on the product.
    In this approach, even the answer to a single query requires the transitive closure
    (i.e., the results of all possible queries), which provides no room for tradeoff
    between preprocessing and query time. Our main contributions are algorithms that
    significantly improve the worst-case running time of the traditional approach,
    and provide various tradeoffs depending on the number of queries. For example,
    in a concurrent system of two components, the traditional approach requires hexic
    time in the worst case for answering one query as well as computing the transitive
    closure, whereas we show that with one-time preprocessing in almost cubic time,
    each subsequent query can be answered in at most linear time, and even the transitive
    closure can be computed in almost quartic time. Furthermore, we establish conditional
    optimality results showing that the worst-case running time of our algorithms
    cannot be improved without achieving major breakthroughs in graph algorithms (i.e.,
    improving the worst-case bound for the shortest path problem in general graphs).
    Preliminary experimental results show that our algorithms perform favorably on
    several benchmarks.

  text: POMDPs are standard models for probabilistic planning problems, where an agent
    interacts with an uncertain environment. We study the problem of almost-sure reachability,
    where given a set of target states, the question is to decide whether there is
    a policy to ensure that the target set is reached with probability 1 (almost-surely).
    While in general the problem is EXPTIME-complete, in many practical cases policies
    with a small amount of memory suffice. Moreover, the existing solution to the
    problem is explicit, which first requires to construct explicitly an exponential
    reduction to a belief-support MDP. In this work, we first study the existence
    of observation-stationary strategies, which is NP-complete, and then small-memory
    strategies. We present a symbolic algorithm by an efficient encoding to SAT and
    using a SAT solver for the problem. We report experimental results demonstrating
    the scalability of our symbolic (SAT-based) approach.

  text: A comprehensive understanding of the clonal evolution of cancer is critical
    for understanding neoplasia. Genome-wide sequencing data enables evolutionary
    studies at unprecedented depth. However, classical phylogenetic methods often
    struggle with noisy sequencing data of impure DNA samples and fail to detect subclones
    that have different evolutionary trajectories. We have developed a tool, called
    Treeomics, that allows us to reconstruct the phylogeny of a cancer with commonly
    available sequencing technologies. Using Bayesian inference and Integer Linear
    Programming, robust phylogenies consistent with the biological processes underlying
    cancer evolution were obtained for pancreatic, ovarian, and prostate cancers.
    Furthermore, Treeomics correctly identified sequencing artifacts such as those
    resulting from low statistical power; nearly 7% of variants were misclassified
    by conventional statistical methods. These artifacts can skew phylogenies by creating
    illusory tumor heterogeneity among distinct samples. Importantly, we show that
    the evolutionary trees generated with Treeomics are mathematically optimal.
