  text: Fault-tolerant distributed algorithms play an important role in ensuring the
    reliability of many software applications. In this paper we consider distributed
    algorithms whose computations are organized in rounds. To verify the correctness
    of such algorithms, we reason about (i) properties (such as invariants) of the
    state, (ii) the transitions controlled by the algorithm, and (iii) the communication
    graph. We introduce a logic that addresses these points, and contains set comprehensions
    with cardinality constraints, function symbols to describe the local states of
    each process, and a limited form of quantifier alternation to express the verification
    conditions. We show its use in automating the verification of consensus algorithms.
    In particular, we give a semi-decision procedure for the unsatisfiability problem
    of the logic and identify a decidable fragment. We successfully applied our framework
    to verify the correctness of a variety of consensus algorithms tolerant to both
    benign faults (message loss, process crashes) and value faults (message corruption).

  text: 'Probabilistic programs are usual functional or imperative programs with two
    added constructs: (1) the ability to draw values at random from distributions,
    and (2) the ability to condition values of variables in a program via observations.
    Models from diverse application areas such as computer vision, coding theory,
    cryptographic protocols, biology and reliability analysis can be written as probabilistic
    programs. Probabilistic inference is the problem of computing an explicit representation
    of the probability distribution implicitly specified by a probabilistic program.
    Depending on the application, the desired output from inference may vary-we may
    want to estimate the expected value of some function f with respect to the distribution,
    or the mode of the distribution, or simply a set of samples drawn from the distribution.
    In this paper, we describe connections this research area called \Probabilistic
    Programming&quot; has with programming languages and software engineering, and
    this includes language design, and the static and dynamic analysis of programs.
    We survey current state of the art and speculate on promising directions for future
    research.'

  text: In this paper we present INTERHORN, a solver for recursion-free Horn clauses.
    The main application domain of INTERHORN lies in solving interpolation problems
    arising in software verification. We show how a range of interpolation problems,
    including path, transition, nested, state/transition and well-founded interpolation
    can be handled directly by INTERHORN. By detailing these interpolation problems
    and their Horn clause representations, we hope to encourage the emergence of a
    common back-end interpolation interface useful for diverse verification tools.

  text: Boolean controllers for systems with complex datapaths are often very difficult
    to implement correctly, in particular when concurrency is involved. Yet, in many
    instances it is easy to formally specify correctness. For example, the specification
    for the controller of a pipelined processor only has to state that the pipelined
    processor gives the same results as a non-pipelined reference design. This makes
    such controllers a good target for automated synthesis. However, an efficient
    abstraction for the complex datapath elements is needed, as a bit-precise description
    is often infeasible. We present Suraq, the first controller synthesis tool which
    uses uninterpreted functions for the abstraction. Quantified firstorder formulas
    (with specific quantifier structure) serve as the specification language from
    which Suraq synthesizes Boolean controllers. Suraq transforms the specification
    into an unsatisfiable SMT formula, and uses Craig interpolation to compute its
    results. Using Suraq, we were able to synthesize a controller (consisting of two
    Boolean signals) for a five-stage pipelined DLX processor in roughly one hour
    and 15 minutes.

  text: We investigate the problem of checking if a finite-state transducer is robust
    to uncertainty in its input. Our notion of robustness is based on the analytic
    notion of Lipschitz continuity - a transducer is K-(Lipschitz) robust if the perturbation
    in its output is at most K times the perturbation in its input. We quantify input
    and output perturbation using similarity functions. We show that K-robustness
    is undecidable even for deterministic transducers. We identify a class of functional
    transducers, which admits a polynomial time automata-theoretic decision procedure
    for K-robustness. This class includes Mealy machines and functional letter-to-letter
    transducers. We also study K-robustness of nondeterministic transducers. Since
    a nondeterministic transducer generates a set of output words for each input word,
    we quantify output perturbation using setsimilarity functions. We show that K-robustness
    of nondeterministic transducers is undecidable, even for letter-to-letter transducers.
    We identify a class of set-similarity functions which admit decidable K-robustness
    of letter-to-letter transducers.

  text: We present a formal framework for repairing infinite-state, imperative, sequential
    programs, with (possibly recursive) procedures and multiple assertions; the framework
    can generate repaired programs by modifying the original erroneous program in
    multiple program locations, and can ensure the readability of the repaired program
    using user-defined expression templates; the framework also generates a set of
    inductive assertions that serve as a proof of correctness of the repaired program.
    As a step toward integrating programmer intent and intuition in automated program
    repair, we present a cost-aware formulation - given a cost function associated
    with permissible statement modifications, the goal is to ensure that the total
    program modification cost does not exceed a given repair budget. As part of our
    predicate abstractionbased solution framework, we present a sound and complete
    algorithm for repair of Boolean programs. We have developed a prototype tool based
    on SMT solving and used it successfully to repair diverse errors in benchmark
    C programs.

  text: "Model-based testing is a promising technology for black-box software and
    hardware testing, in which test cases are generated automatically from high-level
    specifications. Nowadays, systems typically consist of multiple interacting components
    and, due to their complexity, testing presents a considerable portion of the effort
    and cost in the design process. Exploiting the compositional structure of system
    specifications can considerably reduce the effort in model-based testing. Moreover,
    inferring properties about the system from testing its individual components allows
    the designer to reduce the amount of integration testing.\r\nIn this paper, we
    study compositional properties of the IOCO-testing theory. We propose a new approach
    to composition and hiding operations, inspired by contract-based design and interface
    theories. These operations preserve behaviors that are compatible under composition
    and hiding, and prune away incompatible ones. The resulting specification characterizes
    the input sequences for which the unit testing of components is sufficient to
    infer the correctness of component integration without the need for further tests.
    We provide a methodology that uses these results to minimize integration testing
    effort, but also to detect potential weaknesses in specifications. While we focus
    on asynchronous models and the IOCO conformance relation, the resulting methodology
    can be applied to a broader class of systems."

  text: As hybrid systems involve continuous behaviors, they should be evaluated by
    quantitative methods, rather than qualitative methods. In this paper we adapt
    a quantitative framework, called model measuring, to the hybrid systems domain.
    The model-measuring problem asks, given a model M and a specification, what is
    the maximal distance such that all models within that distance from M satisfy
    (or violate) the specification. A distance function on models is given as part
    of the input of the problem. Distances, especially related to continuous behaviors
    are more natural in the hybrid case than the discrete case. We are interested
    in distances represented by monotonic hybrid automata, a hybrid counterpart of
    (discrete) weighted automata, whose recognized timed languages are monotone (w.r.t.
    inclusion) in the values of parameters.The contributions of this paper are twofold.
    First, we give sufficient conditions under which the model-measuring problem can
    be solved. Second, we discuss the modeling of distances and applications of the
    model-measuring problem.

  text: "We define the model-measuring problem: given a model M and specification
    φ, what is the maximal distance ρ such that all models M'within distance ρ from
    M satisfy (or violate)φ. The model measuring problem presupposes a distance function
    on models. We concentrate on automatic distance functions, which are defined by
    weighted automata.\r\nThe model-measuring problem subsumes several generalizations
    of the classical model-checking problem, in particular, quantitative model-checking
    problems that measure the degree of satisfaction of a specification, and robustness
    problems that measure how much a model can be perturbed without violating the
    specification.\r\nWe show that for automatic distance functions, and ω-regular
    linear-time and branching-time specifications, the model-measuring problem can
    be solved.\r\nWe use automata-theoretic model-checking methods for model measuring,
    replacing the emptiness question for standard word and tree automata by the optimal-weight
    question for the weighted versions of these automata. We consider weighted automata
    that accumulate weights by maximizing, summing, discounting, and limit averaging.
    \r\nWe give several examples of using the model-measuring problem to compute various
    notions of robustness and quantitative satisfaction for temporal specifications."

  text: "Simulation is an attractive alternative for language inclusion for automata
    as it is an under-approximation of language inclusion, but usually has much lower
    complexity. For non-deterministic automata, while language inclusion is PSPACE-complete,
    simulation can be computed in polynomial time. Simulation has also been extended
    in two orthogonal directions, namely, (1) fair simulation, for simulation over
    specified set of infinite runs; and (2) quantitative simulation, for simulation
    between weighted automata. Again, while fair trace inclusion is PSPACE-complete,
    fair simulation can be computed in polynomial time. For weighted automata, the
    (quantitative) language inclusion problem is undecidable for mean-payoff automata
    and the decidability is open for discounted-sum automata, whereas the (quantitative)
    simulation reduce to mean-payoff games and discounted-sum games, which admit pseudo-polynomial
    time algorithms.\r\n\r\nIn this work, we study (quantitative) simulation for weighted
    automata with Büchi acceptance conditions, i.e., we generalize fair simulation
    from non-weighted automata to weighted automata. We show that imposing Büchi acceptance
    conditions on weighted automata changes many fundamental properties of the simulation
    games. For example, whereas for mean-payoff and discounted-sum games, the players
    do not need memory to play optimally; we show in contrast that for simulation
    games with Büchi acceptance conditions, (i) for mean-payoff objectives, optimal
    strategies for both players require infinite memory in general, and (ii) for discounted-sum
    objectives, optimal strategies need not exist for both players. While the simulation
    games with Büchi acceptance conditions are more complicated (e.g., due to infinite-memory
    requirements for mean-payoff objectives) as compared to their counterpart without
    Büchi acceptance conditions, we still present pseudo-polynomial time algorithms
    to solve simulation games with Büchi acceptance conditions for both weighted mean-payoff
    and weighted discounted-sum automata."

  text: 'We present a tool for translating LTL formulae into deterministic ω-automata.
    It is the first tool that covers the whole LTL that does not use Safra’s determinization
    or any of its variants. This leads to smaller automata. There are several outputs
    of the tool: firstly, deterministic Rabin automata, which are the standard input
    for probabilistic model checking, e.g. for the probabilistic model-checker PRISM;
    secondly, deterministic generalized Rabin automata, which can also be used for
    probabilistic model checking and are sometimes by orders of magnitude smaller.
    We also link our tool to PRISM and show that this leads to a significant speed-up
    of probabilistic LTL model checking, especially with the generalized Rabin automata.'

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

  text: 'We consider a continuous-time Markov chain (CTMC) whose state space is partitioned
    into aggregates, and each aggregate is assigned a probability measure. A sufficient
    condition for defining a CTMC over the aggregates is presented as a variant of
    weak lumpability, which also characterizes that the measure over the original
    process can be recovered from that of the aggregated one. We show how the applicability
    of de-aggregation depends on the initial distribution. The application section
    is devoted to illustrate how the developed theory aids in reducing CTMC models
    of biochemical systems particularly in connection to protein-protein interactions.
    We assume that the model is written by a biologist in form of site-graph-rewrite
    rules. Site-graph-rewrite rules compactly express that, often, only a local context
    of a protein (instead of a full molecular species) needs to be in a certain configuration
    in order to trigger a reaction event. This observation leads to suitable aggregate
    Markov chains with smaller state spaces, thereby providing sufficient reduction
    in computational complexity. This is further exemplified in two case studies:
    simple unbounded polymerization and early EGFR/insulin crosstalk.'

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

  text: The classical (boolean) notion of refinement for behavioral interfaces of
    system components is the alternating refinement preorder. In this paper, we define
    a distance for interfaces, called interface simulation distance. It makes the
    alternating refinement preorder quantitative by, intuitively, tolerating errors
    (while counting them) in the alternating simulation game. We show that the interface
    simulation distance satisfies the triangle inequality, that the distance between
    two interfaces does not increase under parallel composition with a third interface,
    that the distance between two interfaces can be bounded from above and below by
    distances between abstractions of the two interfaces, and how to synthesize an
    interface from incompatible requirements. We illustrate the framework, and the
    properties of the distances under composition of interfaces, with two case studies.

  text: ' A discounted-sum automaton (NDA) is a nondeterministic finite automaton
    with edge weights, valuing a run by the discounted sum of visited edge weights.
    More precisely, the weight in the i-th position of the run is divided by λi, where
    the discount factor λ is a fixed rational number greater than 1. The value of
    a word is the minimal value of the automaton runs on it. Discounted summation
    is a common and useful measuring scheme, especially for infinite sequences, reflecting
    the assumption that earlier weights are more important than later weights. Unfortunately,
    determinization of NDAs, which is often essential in formal verification, is,
    in general, not possible. We provide positive news, showing that every NDA with
    an integral discount factor is determinizable. We complete the picture by proving
    that the integers characterize exactly the discount factors that guarantee determinizability:
    for every nonintegral rational discount factor λ, there is a nondeterminizable
    λ-NDA. We also prove that the class of NDAs with integral discount factors enjoys
    closure under the algebraic operations min, max, addition, and subtraction, which
    is not the case for general NDAs nor for deterministic NDAs. For general NDAs,
    we look into approximate determinization, which is always possible as the influence
    of a word''s suffix decays. We show that the naive approach, of unfolding the
    automaton computations up to a sufficient level, is doubly exponential in the
    discount factor. We provide an alternative construction for approximate determinization,
    which is singly exponential in the discount factor, in the precision, and in the
    number of states. We also prove matching lower bounds, showing that the exponential
    dependency on each of these three parameters cannot be avoided. All our results
    hold equally for automata over finite words and for automata over infinite words. '

  text: We present a general framework for applying machine-learning algorithms to
    the verification of Markov decision processes (MDPs). The primary goal of these
    techniques is to improve performance by avoiding an exhaustive exploration of
    the state space. Our framework focuses on probabilistic reachability, which is
    a core property for verification, and is illustrated through two distinct instantiations.
    The first assumes that full knowledge of the MDP is available, and performs a
    heuristic-driven partial exploration of the model, yielding precise lower and
    upper bounds on the required probability. The second tackles the case where we
    may only sample the MDP, and yields probabilistic guarantees, again in terms of
    both the lower and upper bounds, which provides efficient stopping criteria for
    the approximation. The latter is the first extension of statistical model checking
    for unbounded properties inMDPs. In contrast with other related techniques, our
    approach is not restricted to time-bounded (finite-horizon) or discounted properties,
    nor does it assume any particular properties of the MDP. We also show how our
    methods extend to LTL objectives. We present experimental results showing the
    performance of our framework on several examples.

  text: 'Recently there has been a significant effort to add 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, several basic system properties such as average
    response time cannot be expressed with weighted automata. In this work, we introduce
    nested weighted automata as a new formalism for expressing important quantitative
    properties such as average response time. We establish an almost complete decidability
    picture for the basic decision problems for nested weighted automata, and illustrate
    its applicability in several domains.  '

  text: Recently, there has been an effort to add quantitative objectives to formal
    verification and synthesis. We introduce and investigate the extension of temporal
    logics with quantitative atomic assertions. At the heart of quantitative objectives
    lies the accumulation of values along a computation. It is often the accumulated
    sum, as with energy objectives, or the accumulated average, as with 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 (or Boolean) 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 in time. We also allow the path-accumulation assertions
    LimInfAvg(v) ≥ c and LimSupAvg(v) ≥ c, referring to the average value along an
    entire infinite computation. We study the border of decidability for such quantitative
    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 with
    both prefix-accumulation assertions, or extending LTL with both path-accumulation
    assertions, results in temporal logics whose model-checking problem is decidable.
    Moreover, the prefix-accumulation assertions may be generalized with &quot;controlled
    accumulation,&quot; allowing, for example, to specify constraints on the average
    waiting time between a request and a grant. On the negative side, we show that
    this branching-time logic is, in a sense, the maximal logic with one or both of
    the prefix-accumulation assertions that permits a decidable model-checking procedure.
    Extending a temporal logic that has the EG or EU modalities, such as CTL or LTL,
    makes the problem undecidable.

  text: Extensionality axioms are common when reasoning about data collections, such
    as arrays and functions in program analysis, or sets in mathematics. An extensionality
    axiom asserts that two collections are equal if they consist of the same elements
    at the same indices. Using extensionality is often required to show that two collections
    are equal. A typical example is the set theory theorem (∀x)(∀y)x∪y = y ∪x. Interestingly,
    while humans have no problem with proving such set identities using extensionality,
    they are very hard for superposition theorem provers because of the calculi they
    use. In this paper we show how addition of a new inference rule, called extensionality
    resolution, allows first-order theorem provers to easily solve problems no modern
    first-order theorem prover can solve. We illustrate this by running the VAMPIRE
    theorem prover with extensionality resolution on a number of set theory and array
    problems. Extensionality resolution helps VAMPIRE to solve problems from the TPTP
    library of first-order problems that were never solved before by any prover.
