In the paper we establish the xed-parameter complexity for several parameterized decision problems involving models, supported models and stable models of logic programs. We also e...
Abstract. In this paper, we reduce pushdown system (PDS) model checking to a graphtheoretic problem, and apply a fast graph algorithm to improve the running time for model checking...
For concurrent probabilistic programs having process-level nondeterminism, it is often necessary to restrict the class of schedulers that resolve nondeterminism to obtain sound an...

Abstract. Among the branching-time temporal logics used for the specification and verification of systems, CTL+ , FCTL and ECTL+ are the most notable logics for which the precise...
In this paper, we present weighted/priced timed automata, an extension of timed automaton with costs, and solve several interesting problems on that model. Key words: Weighted/pri...
