On Extensions of Process Rewrite Systems: Rewrite Systems with Weak Finite-State Unit
نویسندگان
چکیده
Various classes of infinite-state processes are often specified by rewrite systems. We extend Mayr’s Process Rewrite Systems (PRS) [13] by finite-state unit whose transition function satisfies some restrictions inspired by weak finite automata. We classify these models by their expressiveness and show how the hierarchy of new classes (w.r.t. bisimilarity) is related to both PRS hierarchy of Mayr and two other hierarchies of PRS extensions introduced in [9,22].

Extended Process Rewrite Systems: Expressiveness and Reachability
We unify a view on three extensions of Process Rewrite Systems (PRS) and compare their expressive power with that of PRS. We show that the class of Petri nets is less expressive up to bisimulation equivalence than the class of PA processes extended with a finite state control unit. Further we show our main result that the reachability problem for PRS extended with a so called weak finite state ...
متن کاملReachability is decidable for weakly extended process rewrite systems
Process Rewrite Systems (PRS) are widely accepted as a formalism for the description of infinite-state systems. It is known that the reachability problem for PRS is decidable. The problem becomes undecidable when PRS are extended with a finitestate control unit. In this paper we show that the problem remains decidable when PRS are extended with a weak (i.e. acyclic except for self-loops) finite...
متن کاملOn Termination and Confluence Properties of Disjoint and Constructor-Sharing Conditional Rewrite Systems
We investigate the modularity behaviour of termination and connuence properties of (join) conditional term rewriting systems. We give counterexamples showing that the properties weak termination, weak innermost termination and (strong) innermost termination are not preserved in general under signature extensions. Then we develop suucient conditions for the preservation of these properties under...
متن کاملOn Computing Reachability Sets of Process Rewrite Systems
We consider the problem of symbolic reachability analysis of a class of term rewrite systems called Process Rewrite Systems (PRS). A PRS can be seen as the union of two mutually interdependent sets of term rewrite rules: a prefix rewrite system (or, equivalently, a pushdown system), and a multiset rewrite system (or, equivalently, a Petri net). These systems are natural models for multithreaded...
متن کاملModal Process Rewrite Systems
We consider modal transition systems with infinite state space generated by finite sets of rules. In particular, we extend process rewrite systems to the modal setting and investigate decidability of the modal refinement relation between systems from various subclasses. Since already simulation is undecidable for most of the cases, we focus on the case where either the refined or the refining p...
