    Boolean programs with recursion are convenient abstractions of sequential, imperative programs. Recursive state machines (RSM) serve as machine models for Boolean programs and are semantically equivalent to pushdown automata. ...

    In order to make multithreaded programming manageable, programmers often follow a design principle where they break the problem into tasks which are then solved asynchronously and concurrently on different threads. This ...

    We investigate the problem of model checking Interval-valued Discrete-time Markov Chains (IDTMC). IDTMCs are discrete-time finite Markov Chains for which the exact transition probabilities are not known. Instead in IDTMCs, ...

  • Sen, Koushik; Viswanathan, Mahesh; Agha, Gul A. (2004-12)
    Statistical methods to model check stochastic systems have been, thus far, developed only for a sublogic of continuous stochastic logic (CSL) that does not have steady state operators and unbounded until formulas. In this ...

    The continuous run-time monitoring of the behavior of a system is a technique that is used both as a complementary approach to formal verification and testing to ensure reliability, as well as a means to discover emergent ...

    LTL\GU is a fragment of linear temporal logic (LTL), where negations appear only on propositions, and formulas are built using the temporal operators X (next), F (eventually), G (always), and U (until, with the restriction ...

  • Hendrix, Joe; Ohsaki, Hitoshi; Viswanathan, Mahesh (2006-02)
    In the paper, we introduce a new tree automata framework, called propositional tree automata, capturing the class of tree languages that are closed under an equational theory and Boolean operations. This framework originates ...

    We consider Markov Decision Processes (MDPs) as transformers on probability distributions, where with respect to a scheduler that resolves nondeterminism, the MDP can be seen as exhibiting a behavior that is a sequence of ...

    Initialized hybrid automata with linear differential inclusions and rectangular constraints are hybrid automata where the invariants, guards, resets, and initial values are given by rectangular constraints, the flows are ...

    Verification and Validation (V&V) is a critically important phase in the development life cycle of a simulation model. In the context of network simulation, traditional network simulators perform well in using a simulation ...
