Abstract

Generalized communicating P systems (GCPSs) are tissuelike membrane systems with only rules for moving pairs of objects. Despite their simplicity, they are able to generate any recursively enumerable set of numbers even having restricted variants of communication rules. We show that GCPSs still remain computationally complete if they are given with a singleton alphabet of objects and with only one of the restricted types of rules: parallel-shift, join, presence-move, or chain.
