Two normal forms for rewriting P systems.
Abstract
P systems have been recently introduced by Gh. P\u{a}un as a new model for molecular
computations based on the notion of membrane structure. In this work, we consider
Rewriting P Systems which use electrical charges to move objects between the
membranes. We show that electrical charges, a feature introduced in order to
obtain more ``realistic'' systems, induces simple systems: we define two normal
forms for two variants of Rewriting P Systems which make use of electrical charges.
