Abstract:
AbstractThis paper presents a new type analysis for logic programs. The analysis is performed witha prioritype definitions; and type expressions are formed from a fixed alphabet of type constructors. Non-discriminative union is used to join type information from different sources without loss of precision. An operation that is performed repeatedly during an analysis is to detect if a fixpoint has been reached. This is reduced to checking the emptiness of types. Due to the use of non-discriminative union, the fundamental problem of checking the emptiness of types is more complex in the proposed

Abstract:
In this paper we consider pushdown automata on infinite trees with empty stack as the accepting condition (ω-EPDTA). We provide the following regarding ω-EPDTA: (a) its relationship to other Pushdown automata on infinite trees, (b) a Kleene-Closure theorem and (c) a single exponential time algorithm for checking emptiness. We demonstrate the usefulness of ω-EPDTA through two example applications: defining the temporal uniform inevitability property and specifying a context-free process with unbounded state space, both of which cannot be defined and/or specified by the classical finite state au

Abstract:
This paper addresses the challenges of symbolic model checking and language emptiness checking where the specification is given as an alternating Büchi automaton. We introduce a novel version of Miyano and Hayashi's construction that allows us to directly convert an alternating automaton to a polynomially-sized symbolic structure. We thus avoid building an exponentially-sized explicit representation of the corresponding nondeterministic automaton. For one-weak automata, Gastin and Oddoux' construction produces smaller automata than Miyano and Hayashi's construction. We present a (symbolic) hyb

AbstractWe study satisfiability and infinite-state model checking in ICPDL, which extends Propositional Dynamic Logic (PDL) with intersection and converse operators on programs. The two main results of this paper are that (i) satisfiability is in 2ΕΧΡΤΙΜΕ, thus 2ΕΧΡΤΙΜΕ-complete by an existing lower bound, and (ii) infinite-state model checking of basic process algebras and pushdown systems is also 2ΕΧΡΤΙΜΕ-complete. Both upper bounds are obtained by polynomial time computable reductions to ω-regular tree satisfiability in ICPDL, a reasoning problem that we introduce specifically for this purp

Abstract:
This paper investigates the complexity of Propositional Projection Temporal Logic with Star (PPTL*). To this end, Propositional Projection Temporal Logic (PPTL) is first extended to include projection star. Then, by reducing the emptiness problem of star-free expressions to the problem of the satisfiability of PPTL* formulas, the lower bound of the complexity for the satisfiability of PPTL* formulas is proved to be non-elementary. Then, to prove the decidability of PPTL*, the normal form, normal form graph (NFG) and labelled normal form graph (LNFG) for PPTL* are defined. Also, algorithms for
