Web and peer-to-peer systems have emerged as popular areas in distributed computing, and their integrated usage permits the benefits of both to be exploited. While much work in th...
Timed automata has been used as a powerful formalism for specifying, designing, and analyzing real time systems. We consider the generalization of timed automata to Pushdown Timed ...
Abstract. We describe a new software, pbmodels, that uses pseudo-boolean constraint solvers (PB solvers) to compute stable models of logic programs with weight atoms. To this end, ...
We give a graph theoretical characterization of answer sets of normal logic programs. We show that there is a one-to-one correspondence between answer sets and a special, non-stan...
Abstract. Most attempts at analysing secure information flow in programs are based on domain-specific logics. Though computationally feahese approaches suffer from the need for ...
