  text: Boolean notions of correctness are formalized by preorders on systems. Quantitative
    measures of correctness can be formalized by real-valued distance functions between
    systems, where the distance between implementation and specification provides
    a measure of &quot;fit&quot; or &quot;desirability&quot;. We extend the simulation
    preorder to the quantitative setting by making each player of a simulation game
    pay a certain price for her choices. We use the resulting games with quantitative
    objectives to define three different simulation distances. The correctness distance
    measures how much the specification must be changed in order to be satisfied by
    the implementation. The coverage distance measures how much the implementation
    restricts the degrees of freedom offered by the specification. The robustness
    distance measures how much a system can deviate from the implementation description
    without violating the specification. We consider these distances for safety as
    well as liveness specifications. The distances can be computed in polynomial time
    for safety specifications, and for liveness specifications given by weak fairness
    constraints. We show that the distance functions satisfy the triangle inequality,
    that the distance between two systems does not increase under parallel composition
    with a third system, and that the distance between two systems can be bounded
    from above and below by distances between abstractions of the two systems. These
    properties suggest that our simulation distances provide an appropriate basis
    for a quantitative theory of discrete systems. We also demonstrate how the robustness
    distance can be used to measure how many transmission errors are tolerated by
    error correcting codes.

  text: Many infinite state systems can be seen as well-structured transition systems
    (WSTS), i.e., systems equipped with a well-quasi-ordering on states that is also
    a simulation relation. WSTS are an attractive target for formal analysis because
    there exist generic algorithms that decide interesting verification problems for
    this class. Among the most popular algorithms are acceleration-based forward analyses
    for computing the covering set. Termination of these algorithms can only be guaranteed
    for flattable WSTS. Yet, many WSTS of practical interest are not flattable and
    the question whether any given WSTS is flattable is itself undecidable. We therefore
    propose an analysis that computes the covering set and captures the essence of
    acceleration-based algorithms, but sacrifices precision for guaranteed termination.
    Our analysis is an abstract interpretation whose abstract domain builds on the
    ideal completion of the well-quasi-ordered state space, and a widening operator
    that mimics acceleration and controls the loss of precision of the analysis. We
    present instances of our framework for various classes of WSTS. Our experience
    with a prototype implementation indicates that, despite the inherent precision
    loss, our analysis often computes the precise covering set of the analyzed system.

  text: We describe a framework for reasoning about programs with lists carrying integer
    numerical data. We use abstract domains to describe and manipulate complex constraints
    on configurations of these programs mixing constraints on the shape of the heap,
    sizes of the lists, on the multisets of data stored in these lists, and on the
    data at their different positions. Moreover, we provide powerful techniques for
    automatic validation of Hoare-triples and invariant checking, as well as for automatic
    synthesis of invariants and procedure summaries using modular inter-procedural
    analysis. The approach has been implemented in a tool called Celia and experimented
    successfully on a large benchmark of programs.

  text: Hierarchical Timing Language (HTL) is a coordination language for distributed,
    hard real-time applications. HTL is a hierarchical extension of Giotto and, like
    its predecessor, based on the logical execution time (LET) paradigm of real-time
    programming. Giotto is compiled into code for a virtual machine, called the EmbeddedMachine
    (or E machine). If HTL is targeted to the E machine, then the hierarchicalprogram
    structure needs to be flattened; the flattening makes separatecompilation difficult,
    and may result in E machinecode of exponential size. In this paper, we propose
    a generalization of the E machine, which supports a hierarchicalprogram structure
    at runtime through real-time trigger mechanisms that are arranged in a tree. We
    present the generalized E machine, and a modular compiler for HTL that generates
    code of linear size. The compiler may generate code for any part of a given HTL
    program separately in any order.

  text: We summarize classical and recent results about two-player games played on
    graphs with ω-regular objectives. These games have applications in the verification
    and synthesis of reactive systems. Important distinctions are whether a graph
    game is turn-based or concurrent; deterministic or stochastic; zero-sum or not.
    We cluster known results and open problems according to these classifications.

  text: Interface theories provide a formal framework for component-based development
    of software and hardware which supports the incremental design of systems and
    the independent implementability of components. These capabilities are ensured
    through mathematical properties of the parallel composition operator and the refinement
    relation for components. More recently, a conjunction operation was added to interface
    theories in order to provide support for handling multiple viewpoints, requirements
    engineering, and component reuse. Unfortunately, the conjunction operator does
    not allow independent implementability in general. In this paper, we study conditions
    that need to be imposed on interface models in order to enforce independent implementability
    with respect to conjunction. We focus on multiple viewpoint specifications and
    propose a new compatibility criterion between two interfaces, which we call orthogonality.
    We show that orthogonal interfaces can be refined separately, while preserving
    both orthogonality and composability with other interfaces. We illustrate the
    independent implementability of different viewpoints with a FIFO buffer example.

  text: For programs whose data variables range over Boolean or finite domains, program
    verification is decidable, and this forms the basis of recent tools for software
    model checking. In this article, we consider algorithmic verification of programs
    that use Boolean variables, and in addition, access a single read-only array whose
    length is potentially unbounded, and whose elements range over an unbounded data
    domain. We show that the reachability problem, while undecidable in general, is
    (1) PSPACE-complete for programs in which the array-accessing for-loops are not
    nested, (2) decidable for a restricted class of programs with doubly nested loops.
    The second result establishes connections to automata and logics defining languages
    over data words.

  text: We solve the longstanding open problems of the blow-up involved in the translations,
    when possible, of a nondeterministic Büchi word automaton (NBW) to a nondeterministic
    co-Büchi word automaton (NCW) and to a deterministic co-Büchi word automaton (DCW).
    For the NBW to NCW translation, the currently known upper bound is 2o(nlog n)
    and the lower bound is 1.5n. We improve the upper bound to n2n and describe a
    matching lower bound of 2ω(n). For the NBW to DCW translation, the currently known
    upper bound is 2o(nlog n). We improve it to 2 o(n), which is asymptotically tight.
    Both of our upper-bound constructions are based on a simple subset construction,
    do not involve intermediate automata with richer acceptance conditions, and can
    be implemented symbolically. We continue and solve the open problems of translating
    nondeterministic Streett, Rabin, Muller, and parity word automata to NCW and to
    DCW. Going via an intermediate NBW is not optimal and we describe direct, simple,
    and asymptotically tight constructions, involving a 2o(n) blow-up. The constructions
    are variants of the subset construction, providing a unified approach for translating
    all common classes of automata to NCW and DCW. Beyond the theoretical importance
    of the results, we point to numerous applications of the new constructions. In
    particular, they imply a simple subset-construction based translation, when possible,
    of LTL to deterministic Büchi word automata.

  text: "Quantitative automata are nondeterministic finite automata with edge weights.
    They value a\r\nrun by some function from the sequence of visited weights to the
    reals, and value a word by its\r\nminimal/maximal run. They generalize boolean
    automata, and have gained much attention in\r\nrecent years. Unfortunately, important
    automaton classes, such as sum, discounted-sum, and\r\nlimit-average automata,
    cannot be determinized. Yet, the quantitative setting provides the potential\r\nof
    approximate determinization. We define approximate determinization with respect
    to\r\na distance function, and investigate this potential.\r\nWe show that sum
    automata cannot be determinized approximately with respect to any\r\ndistance
    function. However, restricting to nonnegative weights allows for approximate determinization\r\nwith
    respect to some distance functions.\r\nDiscounted-sum automata allow for approximate
    determinization, as the influence of a word’s\r\nsuffix is decaying. However,
    the naive approach, of unfolding the automaton computations up\r\nto a sufficient
    level, is shown to be doubly exponential in the discount factor. We provide an\r\nalternative
    construction that is singly exponential in the discount factor, in the precision,
    and\r\nin the number of states. We prove matching lower bounds, showing exponential
    dependency on\r\neach of these three parameters.\r\nAverage and limit-average
    automata are shown to prohibit approximate determinization with\r\nrespect to
    any distance function, and this is the case even for two weights, 0 and 1."
acknowledgement: We thank Laurent Doyen for great ideas and valuable help in analyzing
  discounted-sum automata.

  text: Software transactional memories (STM) are described in the literature with
    assumptions of sequentially consistent program execution and atomicity of high
    level operations like read, write, and abort. However, in a realistic setting,
    processors use relaxed memory models to optimize hardware performance. Moreover,
    the atomicity of operations depends on the underlying hardware. This paper presents
    the first approach to verify STMs under relaxed memory models with atomicity of
    32 bit loads and stores, and read-modify-write operations. We describe RML, a
    simple language for expressing concurrent programs. We develop a semantics of
    RML parametrized by a relaxed memory model. We then present our tool, FOIL, which
    takes as input the RML description of an STM algorithm restricted to two threads
    and two variables, and the description of a memory model, and automatically determines
    the locations of fences, which if inserted, ensure the correctness of the restricted
    STM algorithm under the given memory model. We use FOIL to verify DSTM, TL2, and
    McRT STM under the memory models of sequential consistency, total store order,
    partial store order, and relaxed memory order for two threads and two variables.
    Finally, we extend the verification results for DSTM and TL2 to an arbitrary number
    of threads and variables by manually proving that the structural properties of
    STMs are satisfied at the hardware level of atomicity under the considered relaxed
    memory models.

  text: We present a new decidable logic called TREX for expressing constraints about
    imperative tree data structures. In particular, TREX supports a transitive closure
    operator that can express reachability constraints, which often appear in data
    structure invariants. We show that our logic is closed under weakest precondition
    computation, which enables its use for automated software verification. We further
    show that satisfiability of formulas in TREX is decidable in NP. The low complexity
    makes it an attractive alternative to more expensive logics such as monadic second-order
    logic (MSOL) over trees, which have been traditionally used for reasoning about
    tree data structures.

  text: Verification of programs with procedures, multi-threaded programs, and higher-order
    functional programs can be effectively au- tomated using abstraction and refinement
    schemes that rely on spurious counterexamples for abstraction discovery. The analysis
    of counterexam- ples can be automated by a series of interpolation queries, or,
    alterna- tively, as a constraint solving query expressed by a set of recursion
    free Horn clauses. (A set of interpolation queries can be formulated as a single
    constraint over Horn clauses with linear dependency structure between the unknown
    relations.) In this paper we present an algorithm for solving recursion free Horn
    clauses over a combined theory of linear real/rational arithmetic and uninterpreted
    functions. Our algorithm performs resolu- tion to deal with the clausal structure
    and relies on partial solutions to deal with (non-local) instances of functionality
    axioms.

  text: The chemical master equation is a differential equation describing the time
    evolution of the probability distribution over the possible “states” of a biochemical
    system. The solution of this equation is of interest within the systems biology
    field ever since the importance of the molec- ular noise has been acknowledged.
    Unfortunately, most of the systems do not have analytical solutions, and numerical
    solutions suffer from the course of dimensionality and therefore need to be approximated.
    Here, we introduce the concept of tail approximation, which retrieves an approximation
    of the probabilities in the tail of a distribution from the total probability
    of the tail and its conditional expectation. This approximation method can then
    be used to numerically compute the solution of the chemical master equation on
    a subset of the state space, thus fighting the explosion of the state space, for
    which this problem is renowned.

  text: In addition to being correct, a system should be robust, that is, it should
    behave reasonably even after receiving unexpected inputs. In this paper, we summarize
    two formal notions of robustness that we have introduced previously for reactive
    systems. One of the notions is based on assigning costs for failures on a user-provided
    notion of incorrect transitions in a specification. Here, we define a system to
    be robust if a finite number of incorrect inputs does not lead to an infinite
    number of incorrect outputs. We also give a more refined notion of robustness
    that aims to minimize the ratio of output failures to input failures. The second
    notion is aimed at liveness. In contrast to the previous notion, it has no concept
    of recovery from an error. Instead, it compares the ratio of the number of liveness
    constraints that the system violates to the number of liveness constraints that
    the environment violates.

  text: We present a new decidable logic called TREX for expressing constraints about
    imperative tree data structures. In particular, TREX supports a transitive closure
    operator that can express reachability constraints, which often appear in data
    structure invariants. We show that our logic is closed under weakest precondition
    computation, which enables its use for automated software verification. We further
    show that satisfiability of formulas in TREX is decidable in NP. The low complexity
    makes it an attractive alternative to more expensive logics such as monadic second-order
    logic (MSOL) over trees, which have been traditionally used for reasoning about
    tree data structures.

  text: 'Automated termination provers often use the following schema to prove that
    a program terminates: construct a relational abstraction of the program''s transition
    relation and then show that the relational abstraction is well-founded. The focus
    of current tools has been on developing sophisticated techniques for constructing
    the abstractions while relying on known decidable logics (such as linear arithmetic)
    to express them. We believe we can significantly increase the class of programs
    that are amenable to automated termination proofs by identifying more expressive
    decidable logics for reasoning about well-founded relations. We therefore present
    a new decision procedure for reasoning about multiset orderings, which are among
    the most powerful orderings used to prove termination. We show that, using our
    decision procedure, one can automatically prove termination of natural abstractions
    of programs.'

  text: We introduce streaming data string transducers that map input data strings
    to output data strings in a single left-to-right pass in linear time. Data strings
    are (unbounded) sequences of data values, tagged with symbols from a finite set,
    over a potentially infinite data do- main that supports only the operations of
    equality and ordering. The transducer uses a finite set of states, a finite set
    of variables ranging over the data domain, and a finite set of variables ranging
    over data strings. At every step, it can make decisions based on the next in-
    put symbol, updating its state, remembering the input data value in its data variables,
    and updating data-string variables by concatenat- ing data-string variables and
    new symbols formed from data vari- ables, while avoiding duplication. We establish
    that the problems of checking functional equivalence of two streaming transducers,
    and of checking whether a streaming transducer satisfies pre/post verification
    conditions specified by streaming acceptors over in- put/output data-strings,
    are in PSPACE. We identify a class of imperative and a class of functional pro-
    grams, manipulating lists of data items, which can be effectively translated to
    streaming data-string transducers. The imperative pro- grams dynamically modify
    a singly-linked heap by changing next- pointers of heap-nodes and by adding new
    nodes. The main re- striction specifies how the next-pointers can be used for
    traversal. We also identify an expressively equivalent fragment of functional
    programs that traverse a list using syntactically restricted recursive calls.
    Our results lead to algorithms for assertion checking and for checking functional
    equivalence of two programs, written possibly in different programming styles,
    for commonly used routines such as insert, delete, and reverse.

  text: 'Weighted automata map input words to numerical values. Ap- plications of
    weighted automata include formal verification of quantitative properties, as well
    as text, speech, and image processing. A weighted au- tomaton is defined with
    respect to a semiring. For the tropical semiring, the weight of a run is the sum
    of the weights of the transitions taken along the run, and the value of a word
    is the minimal weight of an accepting run on it. In the 90’s, Krob studied the
    decidability of problems on rational series defined with respect to the tropical
    semiring. Rational series are strongly related to weighted automata, and Krob’s
    results apply to them. In par- ticular, it follows from Krob’s results that the
    universality problem (that is, deciding whether the values of all words are below
    some threshold) is decidable for weighted automata defined with respect to the
    tropical semir- ing with domain ∪ {∞}, and that the equality problem is undecidable
    when the domain is ∪ {∞}. In this paper we continue the study of the borders of
    decidability in weighted automata, describe alternative and direct proofs of the
    above results, and tighten them further. Unlike the proofs of Krob, which are
    algebraic in their nature, our proofs stay in the terrain of state machines, and
    the reduction is from the halting problem of a two-counter machine. This enables
    us to significantly simplify Krob’s reasoning, make the un- decidability result
    accessible to the automata-theoretic community, and strengthen it to apply already
    to a very simple class of automata: all the states are accepting, there are no
    initial nor final weights, and all the weights on the transitions are from the
    set {−1, 0, 1}. The fact we work directly with the automata enables us to tighten
    also the decidability re- sults and to show that the universality problem for
    weighted automata defined with respect to the tropical semiring with domain ∪
    {∞}, and in fact even with domain ≥0 ∪ {∞}, is PSPACE-complete. Our results thus
    draw a sharper picture about the decidability of decision problems for weighted
    automata, in both the front of containment vs. universality and the front of the
    ∪ {∞} vs. the ∪ {∞} domains.'
