  text: We propose a flexible exchange format for ω-automata, as typically used in
    formal verification, and implement support for it in a range of established tools.
    Our aim is to simplify the interaction of tools, helping the research community
    to build upon other people’s work. A key feature of the format is the use of very
    generic acceptance conditions, specified by Boolean combinations of acceptance
    primitives, rather than being limited to common cases such as Büchi, Streett,
    or Rabin. Such flexibility in the choice of acceptance conditions can be exploited
    in applications, for example in probabilistic model checking, and furthermore
    encourages the development of acceptance-agnostic tools for automata manipulations.
    The format allows acceptance conditions that are either state-based or transition-based,
    and also supports alternating automata.

  text: Interprocedural analysis is at the heart of numerous applications in programming
    languages, such as alias analysis, constant propagation, etc. Recursive state
    machines (RSMs) are standard models for interprocedural analysis. We consider
    a general framework with RSMs where the transitions are labeled from a semiring,
    and path properties are algebraic with semiring operations. RSMs with algebraic
    path properties can model interprocedural dataflow analysis problems, the shortest
    path problem, the most probable path problem, etc. The traditional algorithms
    for interprocedural analysis focus on path properties where the starting point
    is fixed as the entry point of a specific method. In this work, we consider possible
    multiple queries as required in many applications such as in alias analysis. The
    study of multiple queries allows us to bring in a very important algorithmic distinction
    between the resource usage of the one-time preprocessing vs for each individual
    query. The second aspect that we consider is that the control flow graphs for
    most programs have constant treewidth. Our main contributions are simple and implementable
    algorithms that supportmultiple queries for algebraic path properties for RSMs
    that have constant treewidth. Our theoretical results show that our algorithms
    have small additional one-time preprocessing, but can answer subsequent queries
    significantly faster as compared to the current best-known solutions for several
    important problems, such as interprocedural reachability and shortest path. We
    provide a prototype implementation for interprocedural reachability and intraprocedural
    shortest path that gives a significant speed-up on several benchmarks.

  text: "For deterministic systems, a counterexample to a property can simply be an
    error trace, whereas counterexamples in probabilistic systems are necessarily
    more complex. For instance, a set of erroneous traces with a sufficient cumulative
    probability mass can be used. Since these are too large objects to understand
    and manipulate, compact representations such as subchains have been considered.
    In the case of probabilistic systems with non-determinism, the situation is even
    more complex. While a subchain for a given strategy (or scheduler, resolving non-determinism)
    is a straightforward choice, we take a different approach. Instead, we focus on
    the strategy itself, and extract the most important decisions it makes, and present
    its succinct representation.\r\nThe key tools we employ to achieve this are (1)
    introducing a concept of importance of a state w.r.t. the strategy, and (2) learning
    using decision trees. There are three main consequent advantages of our approach.
    Firstly, it exploits the quantitative information on states, stressing the more
    important decisions. Secondly, it leads to a greater variability and degree of
    freedom in representing the strategies. Thirdly, the representation uses a self-explanatory
    data structure. In summary, our approach produces more succinct and more explainable
    strategies, as opposed to e.g. binary decision diagrams. Finally, our experimental
    results show that we can extract several rules describing the strategy even for
    very large systems that do not fit in memory, and based on the rules explain the
    erroneous behaviour."

  text: We consider the quantitative analysis problem for interprocedural control-flow
    graphs (ICFGs). The input consists of an ICFG, a positive weight function that
    assigns every transition a positive integer-valued number, and a labelling of
    the transitions (events) as good, bad, and neutral events. The weight function
    assigns to each transition a numerical value that represents ameasure of how good
    or bad an event is. The quantitative analysis problem asks whether there is a
    run of the ICFG where the ratio of the sum of the numerical weights of good events
    versus the sum of weights of bad events in the long-run is at least a given threshold
    (or equivalently, to compute the maximal ratio among all valid paths in the ICFG).
    The quantitative analysis problem for ICFGs can be solved in polynomial time,
    and we present an efficient and practical algorithm for the problem. We show that
    several problems relevant for static program analysis, such as estimating the
    worst-case execution time of a program or the average energy consumption of a
    mobile application, can be modeled in our framework. We have implemented our algorithm
    as a tool in the Java Soot framework. We demonstrate the effectiveness of our
    approach with two case studies. First, we show that our framework provides a sound
    approach (no false positives) for the analysis of inefficiently-used containers.
    Second, we show that our approach can also be used for static profiling of programs
    which reasons about methods that are frequently invoked. Our experimental results
    show that our tool scales to relatively large benchmarks, and discovers relevant
    and useful information that can be used to optimize performance of the programs.

  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 multiplicative factor of ϵ in time O(n⋅log(n/ϵ))
    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|))=O(n⋅log(n⋅W)), when the output
    is ab, as compared to the previously best known algorithm with running time O(n2⋅log(n⋅W)).
    Third, for the minimum initial credit problem we show that (i) for general graphs
    the problem can be solved in O(n2⋅m) time and the associated decision problem
    can be solved in O(n⋅m) time, improving the previous known O(n3⋅m⋅log(n⋅W)) and
    O(n2⋅m) bounds, respectively; and (ii) for constant treewidth graphs we present
    an algorithm that requires O(n⋅logn) time, improving the previous known O(n4⋅log(n⋅W))
    bound. We have implemented some of our algorithms and show that they present a
    significant speedup on standard benchmarks.

  text: The synthesis problem asks for the automatic construction of a system from
    its specification. In the traditional setting, the system is “constructed from
    scratch” rather than composed from reusable components. However, this is rare
    in practice, and almost every non-trivial software system relies heavily on the
    use of libraries of reusable components. Recently, Lustig and Vardi introduced
    dataflow and controlflow synthesis from libraries of reusable components. They
    proved that dataflow synthesis is undecidable, while controlflow synthesis is
    decidable. The problem of controlflow synthesis from libraries of probabilistic
    components was considered by Nain, Lustig and Vardi, and was shown to be decidable
    for qualitative analysis (that asks that the specification be satisfied with probability
    1). Our main contribution for controlflow synthesis from probabilistic components
    is to establish better complexity bounds for the qualitative analysis problem,
    and to show that the more general quantitative problem is undecidable. For the
    qualitative analysis, we show that the problem (i) is EXPTIME-complete when the
    specification is given as a deterministic parity word automaton, improving the
    previously known 2EXPTIME upper bound; and (ii) belongs to UP ∩ coUP and is parity-games
    hard, when the specification is given directly as a parity condition on the components,
    improving the previously known EXPTIME upper bound.

  text: The edit distance between two words w1, w2 is the minimal number of word operations
    (letter insertions, deletions, and substitutions) necessary to transform w1 to
    w2. The edit distance generalizes to languages L1,L2, where the edit distance
    is the minimal number k such that for every word from L1 there exists a word in
    L2 with edit distance at most k. We study the edit distance computation problem
    between pushdown automata and their subclasses. The problem of computing edit
    distance to pushdown automata is undecidable, and in practice, the interesting
    question is to compute the edit distance from a pushdown automaton (the implementation,
    a standard model for programs with recursion) to a regular language (the specification).
    In this work, we present a complete picture of decidability and complexity for
    deciding whether, for a given threshold k, the edit distance from a pushdown automaton
    to a finite automaton is at most k.

  text: Population structure can facilitate evolution of cooperation. In a structured
    population, cooperators can form clusters which resist exploitation by defectors.
    Recently, it was observed that a shift update rule is an extremely strong amplifier
    of cooperation in a one dimensional spatial model. For the shift update rule,
    an individual is chosen for reproduction proportional to fecundity; the offspring
    is placed next to the parent; a random individual dies. Subsequently, the population
    is rearranged (shifted) until all individual cells are again evenly spaced out.
    For large population size and a one dimensional population structure, the shift
    update rule favors cooperation for any benefit-to-cost ratio greater than one.
    But every attempt to generalize shift updating to higher dimensions while maintaining
    its strong effect has failed. The reason is that in two dimensions the clusters
    are fragmented by the movements caused by rearranging the cells. Here we introduce
    the natural phenomenon of a repulsive force between cells of different types.
    After a birth and death event, the cells are being rearranged minimizing the overall
    energy expenditure. If the repulsive force is sufficiently high, shift becomes
    a strong promoter of cooperation in two dimensions.

  text: Recently there has been a significant effort to handle quantitative properties
    in formal verification and synthesis. While weighted automata over finite and
    infinite words provide a natural and flexible framework to express quantitative
    properties, perhaps surprisingly, some basic system properties such as average
    response time cannot be expressed using weighted automata, nor in any other know
    decidable formalism. In this work, we introduce nested weighted automata as a
    natural extension of weighted automata which makes it possible to express important
    quantitative properties such as average response time. In nested weighted automata,
    a master automaton spins off and collects results from weighted slave automata,
    each of which computes a quantity along a finite portion of an infinite word.
    Nested weighted automata can be viewed as the quantitative analogue of monitor
    automata, which are used in run-time verification. We establish an almost complete
    decidability picture for the basic decision problems about nested weighted automata,
    and illustrate their applicability in several domains. In particular, nested weighted
    automata can be used to decide average response time properties.

  text: 'We consider Markov decision processes (MDPs) with multiple limit-average
    (or mean-payoff) objectives. There exist two different views: (i) ~the expectation
    semantics, where the goal is to optimize the expected mean-payoff objective, and
    (ii) ~the satisfaction semantics, where the goal is to maximize the probability
    of runs such that the mean-payoff value stays above a given vector. We consider
    optimization with respect to both objectives at once, thus unifying the existing
    semantics. Precisely, the goal is to optimize the expectation while ensuring the
    satisfaction constraint. Our problem captures the notion of optimization with
    respect to strategies that are risk-averse (i.e., Ensure certain probabilistic
    guarantee). Our main results are as follows: First, we present algorithms for
    the decision problems, which are always polynomial in the size of the MDP. We
    also show that an approximation of the Pareto curve can be computed in time polynomial
    in the size of the MDP, and the approximation factor, but exponential in the number
    of dimensions. Second, we present a complete characterization of the strategy
    complexity (in terms of memory bounds and randomization) required to solve our
    problem. '

  text: We study the pattern frequency vector for runs in probabilistic Vector Addition
    Systems with States (pVASS). Intuitively, each configuration of a given pVASS
    is assigned one of finitely many patterns, and every run can thus be seen as an
    infinite sequence of these patterns. The pattern frequency vector assigns to each
    run the limit of pattern frequencies computed for longer and longer prefixes of
    the run. If the limit does not exist, then the vector is undefined. We show that
    for one-counter pVASS, the pattern frequency vector is defined and takes one of
    finitely many values for almost all runs. Further, these values and their associated
    probabilities can be approximated up to an arbitrarily small relative error in
    polynomial time. For stable two-counter pVASS, we show the same result, but we
    do not provide any upper complexity bound. As a byproduct of our study, we discover
    counterexamples falsifying some classical results about stochastic Petri nets
    published in the 80s.

  text: The computation of the winning set for one-pair Streett objectives and for
    k-pair Streett objectives in (standard) graphs as well as in game graphs are central
    problems in computer-aided verification, with application to the verification
    of closed systems with strong fairness conditions, the verification of open systems,
    checking interface compatibility, well-formed ness of specifications, and the
    synthesis of reactive systems. We give faster algorithms for the computation of
    the winning set for (1) one-pair Streett objectives (aka parity-3 problem) in
    game graphs and (2) for k-pair Streett objectives in graphs. For both problems
    this represents the first improvement in asymptotic running time in 15 years.

  text: Which genetic alterations drive tumorigenesis and how they evolve over the
    course of disease and therapy are central questions in cancer biology. Here we
    identify 44 recurrently mutated genes and 11 recurrent somatic copy number variations
    through whole-exome sequencing of 538 chronic lymphocytic leukaemia (CLL) and
    matched germline DNA samples, 278 of which were collected in a prospective clinical
    trial. These include previously unrecognized putative cancer drivers (RPS15, IKZF3),
    and collectively identify RNA processing and export, MYC activity, and MAPK signalling
    as central pathways involved in CLL. Clonality analysis of this large data set
    further enabled reconstruction of temporal relationships between driver events.
    Direct comparison between matched pre-treatment and relapse samples from 59 patients
    demonstrated highly frequent clonal evolution. Thus, large sequencing data sets
    of clinically informative samples enable the discovery of novel genes associated
    with cancer, the network of relationships between the driver events, and their
    impact on disease relapse and clinical outcome.

  text: We consider parametric version of fixed-delay continuoustime Markov chains
    (or equivalently deterministic and stochastic Petri nets, DSPN) where fixed-delay
    transitions are specified by parameters, rather than concrete values. Our goal
    is to synthesize values of these parameters that, for a given cost function, minimise
    expected total cost incurred before reaching a given set of target states. We
    show that under mild assumptions, optimal values of parameters can be effectively
    approximated using translation to a Markov decision process (MDP) whose actions
    correspond to discretized values of these parameters. To this end we identify
    and overcome several interesting phenomena arising in systems with fixed delays.

  text: 'When a new mutant arises in a population, there is a probability it outcompetes
    the residents and fixes. The structure of the population can affect this fixation
    probability. Suppressing population structures reduce the difference between two
    competing variants, while amplifying population structures enhance the difference.
    Suppressors are ubiquitous and easy to construct, but amplifiers for the large
    population limit are more elusive and only a few examples have been discovered.
    Whether or not a population structure is an amplifier of selection depends on
    the probability distribution for the placement of the invading mutant. First,
    we prove that there exist only bounded amplifiers for adversarial placement-that
    is, for arbitrary initial conditions. Next, we show that the Star population structure,
    which is known to amplify for mutants placed uniformly at random, does not amplify
    for mutants that arise through reproduction and are therefore placed proportional
    to the temperatures of the vertices. Finally, we construct population structures
    that amplify for all mutational events that arise through reproduction, uniformly
    at random, or through some combination of the two. '

  text: In many social situations, individuals endeavor to find the single best possible
    partner, but are constrained to evaluate the candidates in sequence. Examples
    include the search for mates, economic partnerships, or any other long-term ties
    where the choice to interact involves two parties. Surprisingly, however, previous
    theoretical work on mutual choice problems focuses on finding equilibrium solutions,
    while ignoring the evolutionary dynamics of decisions. Empirically, this may be
    of high importance, as some equilibrium solutions can never be reached unless
    the population undergoes radical changes and a sufficient number of individuals
    change their decisions simultaneously. To address this question, we apply a mutual
    choice sequential search problem in an evolutionary game-theoretical model that
    allows one to find solutions that are favored by evolution. As an example, we
    study the influence of sequential search on the evolutionary dynamics of cooperation.
    For this, we focus on the classic snowdrift game and the prisoner’s dilemma game.

  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: "\r\nWe 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.'
