  text: In this paper, we present a formal model-driven design approach to establish
    a safety-assured implementation of multifunction vehicle bus controller (MVBC),
    which controls the data transmission among the devices of the vehicle. First,
    the generic models and safety requirements described in International Electrotechnical
    Commission Standard 61375 are formalized as time automata and timed computation
    tree logic formulas, respectively. With model checking tool Uppaal, we verify
    whether or not the constructed timed automata satisfy the formulas and several
    logic inconsistencies in the original standard are detected and corrected. Then,
    we apply the code generation tool Times to generate C code from the verified model,
    which is later synthesized into a real MVBC chip, with some handwriting glue code.
    Furthermore, the runtime verification tool RMOR is applied on the integrated code,
    to verify some safety requirements that cannot be formalized on the timed automata.
    For evaluation, we compare the proposed approach with existing MVBC design methods,
    such as BeagleBone, Galsblock, and Simulink. Experiments show that more ambiguousness
    or bugs in the standard are detected during Uppaal verification, and the generated
    code of Times outperforms the C code generated by others in terms of the synthesized
    binary code size. The errors in the standard have been confirmed and the resulting
    MVBC has been deployed in the real train communication network.

  text: "Simulation is an attractive alternative to language inclusion for automata
    as it is an under-approximation of language inclusion, but usually has much lower
    complexity. 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. 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 in general, whereas the (quantitative) simulation reduces to quantitative
    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, yet they still admit pseudo-polynomial
    time algorithms."

  text: "Time-triggered switched networks are a deterministic communication infrastructure
    used by real-time distributed embedded systems. Due to the criticality of the
    applications running over them, developers need to ensure that end-to-end communication
    is dependable and predictable. Traditional approaches assume static networks that
    are not flexible to changes caused by reconfigurations or, more importantly, faults,
    which are dealt with in the application using redundancy. We adopt the concept
    of handling faults in the switches from non-real-time networks while maintaining
    the required predictability. \r\n\r\nWe study a class of forwarding schemes that
    can handle various types of failures. We consider probabilistic failures. We study
    a class of forwarding schemes that can handle various types of failures. We consider
    probabilistic failures. For a given network with a forwarding scheme and a constant
    ℓ, we compute the {\\em score} of the scheme, namely the probability (induced
    by faults) that at least ℓ messages arrive on time. We reduce the scoring problem
    to a reachability problem on a Markov chain with a &quot;product-like&quot; structure.
    Its special structure allows us to reason about it symbolically, and reduce the
    scoring problem to #SAT. Our solution is generic and can be adapted to different
    networks and other contexts. Also, we show the computational complexity of the
    scoring problem is #P-complete, and we study methods to estimate the score. We
    evaluate the effectiveness of our techniques with an implementation. "

  text: This dissertation concerns the automatic verification of probabilistic systems
    and programs with arrays by statistical and logical methods. Although statistical
    and logical methods are different in nature, we show that they can be successfully
    combined for system analysis. In the first part of the dissertation we present
    a new statistical algorithm for the verification of probabilistic systems with
    respect to unbounded properties, including linear temporal logic. Our algorithm
    often performs faster than the previous approaches, and at the same time requires
    less information about the system. In addition, our method can be generalized
    to unbounded quantitative properties such as mean-payoff bounds. In the second
    part, we introduce two techniques for comparing probabilistic systems. Probabilistic
    systems are typically compared using the notion of equivalence, which requires
    the systems to have the equal probability of all behaviors. However, this notion
    is often too strict, since probabilities are typically only empirically estimated,
    and any imprecision may break the relation between processes. On the one hand,
    we propose to replace the Boolean notion of equivalence by a quantitative distance
    of similarity. For this purpose, we introduce a statistical framework for estimating
    distances between Markov chains based on their simulation runs, and we investigate
    which distances can be approximated in our framework. On the other hand, we propose
    to compare systems with respect to a new qualitative logic, which expresses that
    behaviors occur with probability one or a positive probability. This qualitative
    analysis is robust with respect to modeling errors and applicable to many domains.
    In the last part, we present a new quantifier-free logic for integer arrays, which
    allows us to express counting. Counting properties are prevalent in array-manipulating
    programs, however they cannot be expressed in the quantified fragments of the
    theory of arrays. We present a decision procedure for our logic, and provide several
    complexity results.

  text: 'In this paper, we propose an approach to automatically compute invariant
    clusters for nonlinear semialgebraic hybrid systems. An invariant cluster for
    an ordinary differential equation (ODE) is a multivariate polynomial invariant
    g(u→, x→) = 0, parametric in u→, which can yield an infinite number of concrete
    invariants by assigning different values to u→ so that every trajectory of the
    system can be overapproximated precisely by the intersection of a group of concrete
    invariants. For semialgebraic systems, which involve ODEs with multivariate polynomial
    right-hand sides, given a template multivariate polynomial g(u→, x→), an invariant
    cluster can be obtained by first computing the remainder of the Lie derivative
    of g(u→, x→) divided by g(u→, x→) and then solving the system of polynomial equations
    obtained from the coefficients of the remainder. Based on invariant clusters and
    sum-of-squares (SOS) programming, we present a new method for the safety verification
    of hybrid systems. Experiments on nonlinear benchmark systems from biology and
    control theory show that our approach is efficient. '

  text: Nested weighted automata (NWA) present a robust and convenient automata-theoretic
    formalism for quantitative specifications. Previous works have considered NWA
    that processed input words only in the forward direction. It is natural to allow
    the automata to process input words backwards as well, for example, to measure
    the maximal or average time between a response and the preceding request. We therefore
    introduce and study bidirectional NWA that can process input words in both directions.
    First, we show that bidirectional NWA can express interesting quantitative properties
    that are not expressible by forward-only NWA. Second, for the fundamental decision
    problems of emptiness and universality, we establish decidability and complexity
    results for the new framework which match the best-known results for the special
    case of forward-only NWA. Thus, for NWA, the increased expressiveness of bidirectionality
    is achieved at no additional computational complexity. This is in stark contrast
    to the unweighted case, where bidirectional finite automata are no more expressive
    but exponentially more succinct than their forward-only counterparts.

  text: "This special issue of the Journal on Formal Methods in System Design is dedicated
    to Prof. Helmut Veith, who unexpectedly passed away in March 2016. Helmut Veith
    was a brilliant researcher, inspiring collaborator, passionate mentor, generous
    friend, and valued member of the formal methods community. Helmut was not only
    known for his numerous and influential contributions in the field of automated
    verification (most prominently his work on Counterexample-Guided Abstraction Refinement
    [1,2]), but also for his untiring and passionate efforts for the logic community:
    he co-organized the Vienna Summer of Logic (an event comprising twelve conferences
    and numerous workshops which attracted thousands of researchers from all over
    the world), he initiated the Vienna Center for Logic and Algorithms (which promotes
    international collaboration on logic and algorithms and organizes outreach events
    such as the LogicLounge), and he coordinated the Doctoral Program on Logical Methods
    in Computer Science at TU Wien (currently educating more than 40 doctoral students)
    and a National Research Network on Rigorous Systems Engineering (uniting fifteen
    researchers in Austria to address the challenge of building reliable and safe
    computer\r\nsystems). With his enthusiasm and commitment, Helmut completely reshaped
    the Austrian research landscape in the field of logic and verification in his
    few years as a full professor at TU Wien."

  text: 'The edit distance between two words w 1 , w 2 is the minimal number of word
    operations (letter insertions, deletions, and substitutions) necessary to transform
    w 1 to w 2 . The edit distance generalizes to languages L 1 , L 2 , where the
    edit distance from L 1 to L 2 is the minimal number k such that for every word
    from L 1 there exists a word in L 2 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 a pushdown automaton 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 the following problems: (1) deciding
    whether, for a given threshold k , the edit distance from a pushdown automaton
    to a finite automaton is at most k , and (2) deciding whether the edit distance
    from a pushdown automaton to a finite automaton is finite. '

  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 or in any other known
    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 runtime 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 present a new algorithm for the statistical model checking of Markov chains
    with respect to unbounded temporal properties, including full linear temporal
    logic. The main idea is that we monitor each simulation run on the fly, in order
    to detect quickly if a bottom strongly connected component is entered with high
    probability, in which case the simulation run can be terminated early. As a result,
    our simulation runs are often much shorter than required by termination bounds
    that are computed a priori for a desired level of confidence on a large state
    space. In comparison to previous algorithms for statistical model checking our
    method is not only faster in many cases but also requires less information about
    the system, namely, only the minimum transition probability that occurs in the
    Markov chain. In addition, our method can be generalised to unbounded quantitative
    properties such as mean-payoff bounds. '

  text: Model checking is usually based on a comprehensive traversal of the state
    space. Causality-based model checking is a radically different approach that instead
    analyzes the cause-effect relationships in a program. We give an overview on a
    new class of model checking algorithms that capture the causal relationships in
    a special data structure called concurrent traces. Concurrent traces identify
    key events in an execution history and link them through their cause-effect relationships.
    The model checker builds a tableau of concurrent traces, where the case splits
    represent different causal explanations of a hypothetical error. Causality-based
    model checking has been implemented in the ARCTOR tool, and applied to previously
    intractable multi-threaded benchmarks.

  text: In the analysis of reactive systems a quantitative objective assigns a real
    value to every trace of the system. The value decision problem for a quantitative
    objective requires a trace whose value is at least a given threshold, and the
    exact value decision problem requires a trace whose value is exactly the threshold.
    We compare the computational complexity of the value and exact value decision
    problems for classical quantitative objectives, such as sum, discounted sum, energy,
    and mean-payoff for two standard models of reactive systems, namely, graphs and
    graph games.

  text: Template polyhedra generalize intervals and octagons to polyhedra whose facets
    are orthogonal to a given set of arbitrary directions. They have been employed
    in the abstract interpretation of programs and, with particular success, in the
    reachability analysis of hybrid automata. While previously, the choice of directions
    has been left to the user or a heuristic, we present a method for the automatic
    discovery of directions that generalize and eliminate spurious counterexamples.
    We show that for the class of convex hybrid automata, i.e., hybrid automata with
    (possibly nonlinear) convex constraints on derivatives, such directions always
    exist and can be found using convex optimization. We embed our method inside a
    CEGAR loop, thus enabling the time-unbounded reachability analysis of an important
    and richer class of hybrid automata than was previously possible. We evaluate
    our method on several benchmarks, demonstrating also its superior efficiency for
    the special case of linear hybrid automata.

  text: A Rapidly-exploring Random Tree (RRT) is an algorithm which can search a non-convex
    region of space by incrementally building a space-filling tree. The tree is constructed
    from random points drawn from system’s state space and is biased to grow towards
    large unexplored areas in the system. RRT can provide better coverage of a system’s
    possible behaviors compared with random simulations, but is more lightweight than
    full reachability analysis. In this paper, we explore some of the design decisions
    encountered while implementing a hybrid extension of the RRT algorithm, which
    have not been elaborated on before. In particular, we focus on handling non-determinism,
    which arises due to discrete transitions. We introduce the notion of important
    points to account for this phenomena. We showcase our ideas using heater and navigation
    benchmarks.

  text: Signal regular expressions can specify sequential properties of real-valued
    signals based on threshold conditions, regular operations, and duration constraints.
    In this paper we endow them with a quantitative semantics which indicates how
    robustly a signal matches or does not match a given expression. First, we show
    that this semantics is a safe approximation of a distance between the signal and
    the language defined by the expression. Then, we consider the robust matching
    problem, that is, computing the quantitative semantics of every segment of a given
    signal relative to an expression. We present an algorithm that solves this problem
    for piecewise-constant and piecewise-linear signals and show that for such signals
    the robustness map is a piecewise-linear function. The availability of an indicator
    describing how robustly a signal segment matches some regular pattern provides
    a general framework for quantitative monitoring of cyber-physical systems.

  text: Synchronous programs are easy to specify because the side effects of an operation
    are finished by the time the invocation of the operation returns to the caller.
    Asynchronous programs, on the other hand, are difficult to specify because there
    are side effects due to pending computation scheduled as a result of the invocation
    of an operation. They are also difficult to verify because of the large number
    of possible interleavings of concurrent asynchronous computation threads. We show
    that specifications and correctness proofs for asynchronous programs can be structured
    by introducing the fiction, for proof purposes, that intermediate, non-quiescent
    states of asynchronous operations can be ignored. Then, the task of specification
    becomes relatively simple and the task of verification can be naturally decomposed
    into smaller sub-tasks. The sub-tasks iteratively summarize, guided by the structure
    of an asynchronous program, the atomic effect of non-atomic operations and the
    synchronous effect of asynchronous operations. This structuring of specifications
    and proofs corresponds to the introduction of multiple layers of stepwise refinement
    for asynchronous programs. We present the first proof rule, called synchronization,
    to reduce asynchronous invocations on a lower layer to synchronous invocations
    on a higher layer. We implemented our proof method in CIVL and evaluated it on
    a collection of benchmark programs.

  text: Despite researchers’ efforts in the last couple of decades, reachability analysis
    is still a challenging problem even for linear hybrid systems. Among the existing
    approaches, the most practical ones are mainly based on bounded-time reachable
    set over-approximations. For the purpose of unbounded-time analysis, one important
    strategy is to abstract the original system and find an invariant for the abstraction.
    In this paper, we propose an approach to constructing a new kind of abstraction
    called conic abstraction for affine hybrid systems, and to computing reachable
    sets based on this abstraction. The essential feature of a conic abstraction is
    that it partitions the state space of a system into a set of convex polyhedral
    cones which is derived from a uniform conic partition of the derivative space.
    Such a set of polyhedral cones is able to cut all trajectories of the system into
    almost straight segments so that every segment of a reach pipe in a polyhedral
    cone tends to be straight as well, and hence can be over-approximated tightly
    by polyhedra using similar techniques as HyTech or PHAVer. In particular, for
    diagonalizable affine systems, our approach can guarantee to find an invariant
    for unbounded reachable sets, which is beyond the capability of bounded-time reachability
    analysis tools. We implemented the approach in a tool and experiments on benchmarks
    show that our approach is more powerful than SpaceEx and PHAVer in dealing with
    diagonalizable systems.

  text: We present a computer-aided programming approach to concurrency. The approach
    allows programmers to program assuming a friendly, non-preemptive scheduler, and
    our synthesis procedure inserts synchronization to ensure that the final program
    works even with a preemptive scheduler. The correctness specification is implicit,
    inferred from the non-preemptive behavior. Let us consider sequences of calls
    that the program makes to an external interface. The specification requires that
    any such sequence produced under a preemptive scheduler should be included in
    the set of sequences produced under a non-preemptive scheduler. We guarantee that
    our synthesis does not introduce deadlocks and that the synchronization inserted
    is optimal w.r.t. a given objective function. The solution is based on a finitary
    abstraction, an algorithm for bounded language inclusion modulo an independence
    relation, and generation of a set of global constraints over synchronization placements.
    Each model of the global constraints set corresponds to a correctness-ensuring
    synchronization placement. The placement that is optimal w.r.t. the given objective
    function is chosen as the synchronization solution. We apply the approach to device-driver
    programming, where the driver threads call the software interface of the device
    and the API provided by the operating system. Our experiments demonstrate that
    our synthesis method is precise and efficient. The implicit specification helped
    us find one concurrency bug previously missed when model-checking using an explicit,
    user-provided specification. We implemented objective functions for coarse-grained
    and fine-grained locking and observed that different synchronization placements
    are produced for our experiments, favoring a minimal number of synchronization
    operations or maximum concurrency, respectively.

  text: The behaviour of gene regulatory networks (GRNs) is typically analysed using
    simulation-based statistical testing-like methods. In this paper, we demonstrate
    that we can replace this approach by a formal verification-like method that gives
    higher assurance and scalability. We focus on Wagner’s weighted GRN model with
    varying weights, which is used in evolutionary biology. In the model, weight parameters
    represent the gene interaction strength that may change due to genetic mutations.
    For a property of interest, we synthesise the constraints over the parameter space
    that represent the set of GRNs satisfying the property. We experimentally show
    that our parameter synthesis procedure computes the mutational robustness of GRNs—an
    important problem of interest in evolutionary biology—more efficiently than the
    classical simulation method. We specify the property in linear temporal logic.
    We employ symbolic bounded model checking and SMT solving to compute the space
    of GRNs that satisfy the property, which amounts to synthesizing a set of linear
    constraints on the weights.
