Deterministic finite automata (DFAs) are widely used to perform regular expression matching in linear time. Several techniques have been proposed to compress DFAs in order to redu...
We re-examine vacuity in temporal logic model checking. We note two disturbing phenomena in recent results in this area. The first indicates that not all vacuities detected in prac...
We consider message sequence charts enriched with timing constraints between pairs of events. As in the untimed setting, an infinite family of time-constrained message sequence cha...
Abstract. We consider the problem of verifying the safety of wellstructured transition systems (WSTS) with auxiliary storage. WSTSs with storage are automata that have (possibly) i...
