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 ...
A generic format for adaptive vague logics is presented. The concrete adaptive vague logics based on this format are able to (1) identify sentences as vague or non-vague in the con...
