  text: 'The target discounted-sum problem is the following: Given a rational discount
    factor 0 < λ < 1 and three rational values a, b, and t, does there exist a finite
    or an infinite sequence w ε(a, b)∗ or w ε(a, b)w, such that Σ|w| i=0 w(i)λi equals
    t? The problem turns out to relate to many fields of mathematics and computer
    science, and its decidability question is surprisingly hard to solve. We solve
    the finite version of the problem, and show the hardness of the infinite version,
    linking it to various areas and open problems in mathematics and computer science:
    β-expansions, discounted-sum automata, piecewise affine maps, and generalizations
    of the Cantor set. We provide some partial results to the infinite version, among
    which are solutions to its restriction to eventually-periodic sequences and to
    the cases that λ λ 1/2 or λ = 1/n, for every n ε N. We use our results for solving
    some open problems on discounted-sum automata, among which are the exact-value
    problem for nondeterministic automata over finite words and the universality and
    inclusion problems for functional automata. '

  text: Fault-tolerant distributed algorithms play an important role in many critical/high-availability
    applications. These algorithms are notoriously difficult to implement correctly,
    due to asynchronous communication and the occurrence of faults, such as the network
    dropping messages or computers crashing. Nonetheless there is surprisingly little
    language and verification support to build distributed systems based on fault-tolerant
    algorithms. In this paper, we present some of the challenges that a designer has
    to overcome to implement a fault-tolerant distributed system. Then we review different
    models that have been proposed to reason about distributed algorithms and sketch
    how such a model can form the basis for a domain-specific programming language.
    Adopting a high-level programming model can simplify the programmer's life and
    make the code amenable to automated verification, while still compiling to efficiently
    executable code. We conclude by summarizing the current status of an ongoing language
    design and implementation project that is based on this idea.

  text: 'We consider Markov decision processes (MDPs) which are a standard model for
    probabilistic systems. We focus on qualitative properties for MDPs 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 of MDPs with respect to qualitative properties, and present
    discrete graph algorithms with quadratic complexity to compute the simulation
    relation. We present an automated technique for assume-guarantee style reasoning
    for compositional analysis of two-player games by giving a counterexample guided
    abstraction-refinement approach to compute our new simulation relation. We show
    a tight link between two-player games and MDPs, and as a consequence the results
    for games are lifted to MDPs with qualitative properties. We have implemented
    our algorithms and show that the compositional analysis leads to significant improvements. '

  text: We extend the theory of input-output conformance with operators for merge
    and quotient. The former is useful when testing against multiple requirements
    or views. The latter can be used to generate tests for patches of an already tested
    system. Both operators can combine systems with different action alphabets, which
    is usually the case when constructing complex systems and specifications from
    parts, for instance different views as well as newly defined functionality of
    a~previous version of the system.

  text: Systems biology rests on the idea that biological complexity can be better
    unraveled through the interplay of modeling and experimentation. However, the
    success of this approach depends critically on the informativeness of the chosen
    experiments, which is usually unknown a priori. Here, we propose a systematic
    scheme based on iterations of optimal experiment design, flow cytometry experiments,
    and Bayesian parameter inference to guide the discovery process in the case of
    stochastic biochemical reaction networks. To illustrate the benefit of our methodology,
    we apply it to the characterization of an engineered light-inducible gene expression
    circuit in yeast and compare the performance of the resulting model with models
    identified from nonoptimal experiments. In particular, we compare the parameter
    posterior distributions and the precision to which the outcome of future experiments
    can be predicted. Moreover, we illustrate how the identified stochastic model
    can be used to determine light induction patterns that make either the average
    amount of protein or the variability in a population of cells follow a desired
    profile. Our results show that optimal experiment design allows one to derive
    models that are accurate enough to precisely predict and regulate the protein
    expression in heterogeneous cell populations over extended periods of time.

  text: 'Many stochastic models of biochemical reaction networks contain some chemical
    species for which the number of molecules that are present in the system can only
    be finite (for instance due to conservation laws), but also other species that
    can be present in arbitrarily large amounts. The prime example of such networks
    are models of gene expression, which typically contain a small and finite number
    of possible states for the promoter but an infinite number of possible states
    for the amount of mRNA and protein. One of the main approaches to analyze such
    models is through the use of equations for the time evolution of moments of the
    chemical species. Recently, a new approach based on conditional moments of the
    species with infinite state space given all the different possible states of the
    finite species has been proposed. It was argued that this approach allows one
    to capture more details about the full underlying probability distribution with
    a smaller number of equations. Here, I show that the result that less moments
    provide more information can only stem from an unnecessarily complicated description
    of the system in the classical formulation. The foundation of this argument will
    be the derivation of moment equations that describe the complete probability distribution
    over the finite state space but only low-order moments over the infinite state
    space. I will show that the number of equations that is needed is always less
    than what was previously claimed and always less than the number of conditional
    moment equations up to the same order. To support these arguments, a symbolic
    algorithm is provided that can be used to derive minimal systems of unconditional
    moment equations for models with partially finite state space. '

  text: We present XSpeed a parallel state-space exploration algorithm for continuous
    systems with linear dynamics and nondeterministic inputs. The motivation of having
    parallel algorithms is to exploit the computational power of multi-core processors
    to speed-up performance. The parallelization is achieved on two fronts. First,
    we propose a parallel implementation of the support function algorithm by sampling
    functions in parallel. Second, we propose a parallel state-space exploration by
    slicing the time horizon and computing the reachable states in the time slices
    in parallel. The second method can be however applied only to a class of linear
    systems with invertible dynamics and fixed input. A GP-GPU implementation is also
    presented following a lazy evaluation strategy on support functions. The parallel
    algorithms are implemented in the tool XSpeed. We evaluated the performance on
    two benchmarks including an 28 dimension Helicopter model. Comparison with the
    sequential counterpart shows a maximum speed-up of almost 7× on a 6 core, 12 thread
    Intel Xeon CPU E5-2420 processor. Our GP-GPU implementation shows a maximum speed-up
    of 12× over the sequential implementation and 53× over SpaceEx (LGG scenario),
    the state of the art tool for reachability analysis of linear hybrid systems.
    Experiments illustrate that our parallel algorithm with time slicing not only
    speeds-up performance but also improves precision.

  text: Quantitative extensions of temporal logics have recently attracted significant
    attention. In this work, we study frequency LTL (fLTL), an extension of LTL which
    allows to speak about frequencies of events along an execution. Such an extension
    is particularly useful for probabilistic systems that often cannot fulfil strict
    qualitative guarantees on the behaviour. It has been recently shown that controller
    synthesis for Markov decision processes and fLTL is decidable when all the bounds
    on frequencies are 1. As a step towards a complete quantitative solution, we show
    that the problem is decidable for the fragment fLTL\GU, where U does not occur
    in the scope of G (but still F can). Our solution is based on a novel translation
    of such quantitative formulae into equivalent deterministic automata.

  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: "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: Multiaffine hybrid automata (MHA) represent a powerful formalism to model
    complex dynamical systems. This formalism is particularly suited for the representation
    of biological systems which often exhibit highly non-linear behavior. In this
    paper, we consider the problem of parameter identification for MHA. We present
    an abstraction of MHA based on linear hybrid automata, which can be analyzed by
    the SpaceEx model checker. This abstraction enables a precise handling of time-dependent
    properties. We demonstrate the potential of our approach on a model of a genetic
    regulatory network and a myocyte model.

  text: 'In this paper, we present the first steps toward a runtime verification framework
    for monitoring hybrid and cyber-physical systems (CPS) development tools based
    on randomized differential testing. The development tools include hybrid systems
    reachability analysis tools, model-based development environments like Simulink/Stateflow
    (SLSF), etc. First, hybrid automaton models are randomly generated. Next, these
    hybrid automaton models are translated to a number of different tools (currently,
    SpaceEx, dReach, Flow*, HyCreate, and the MathWorks’ Simulink/Stateflow) using
    the HyST source transformation and translation tool. Then, the hybrid automaton
    models are executed in the different tools and their outputs are parsed. The final
    step is the differential comparison: the outputs of the different tools are compared.
    If the results do not agree (in the sense that an analysis or verification result
    from one tool does not match that of another tool, ignoring timeouts, etc.), a
    candidate bug is flagged and the model is saved for future analysis by the user.
    The process then repeats and the monitoring continues until the user terminates
    the process. We present preliminary results that have been useful in identifying
    a few bugs in the analysis methods of different development tools, and in an earlier
    version of HyST.'

  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: 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: 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: 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: 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.
