Abstract. We revise multiset rewriting with name binding, by combining the two main existing approaches to the study of concurrency by means of multiset rewriting, multiset rewriti...
We apply language theory to compare the expressive power of models that extend Petri nets with features like colored tokens and/or whole place operations. Specifically, we conside...
Abstract. This paper deals with the parallel raytracing part of virtualreality system PROLAND, developed at the home institution of authors. It describes an actual implementation o...
The complexity of the reachability problem for live and safe free-choice Petri nets has been open for several years. Several partial results seemed to indicate that the problem is...
