Our aim is to allow (pairs of) productions which are possibly not parallel independent, to be applied in parallel, provided that they are not mutually exclusive. The notion of synchronized composition we propose is not comparable to amalgamation [BFH87], since two productions which are amalgable

In this paper it is shown that, if one refines the notion of a computation structure in a suitable way, then each computation structure can be decomposed according to an

Graph unification and matching,It is shown that a restricted form of graph unification corresponds to solving linear Diophantine equations, and hence is decidable. For graph matching, transformation rules are given which compute all (pure) solutions to a matching problem. The matching concept suggests a new graph rewriting approa

A graph rewriting framework for Statecharts semantics,ures. This is exemplified considering Statecharts in a variant allowing dynamic creation of processes. Graph rewriting rules give the semantics of Statecharts in such interpretation. Standard Statecharts semantics can be recovered by suitably restricting derivation sequences that describe behaviours

Programmed graph transformations and graph transformation units in GRACE,ata structures. Unfortunately, pure rule-based approaches are not well prepared for expressing any kind of procedural knowledge. Therefore, various extensions were proposed which regulate the application of rewrite rales. This paper compares already existing regulation mechanisms and proposes a new
