On the Computational Power of 1-Deterministic and Sequential P Systems

The original definition of P-systems calls for rules to be applied in a maximally parallel fashion. However, in some cases a sequential model may be a more reasonable assumption. Here we study the computational power of different variants of sequential P-systems. Initially we look at cooperative systems operating on symbol objects and without prioritized rules, but which allow membrane dissolut...

On P Systems Operating in Sequential Mode

In the standard definition of a P system, a computation step consists of a parallel application of a “maximal” set of nondeterministically chosen rules. Referring to this system as a parallel P system, we consider in this paper a sequential P system, in which each step consists of an application of a single nondeterministically chosen rule. We show the following: 1. For 1-membrane catalytic sys...

Effect Estimation Method of Parallel Computing Based on Dynamic Generation of Equivalent Transformation Rules Dynamic Generation of Equivalent Transformation Rules

Recent studies in parallel computing have mainly focused on physically producing multiple computing sites for computational speed-up and not considered theories and methodologies, which are the essence of parallel computing, and correctness as well. It means that the studies have mostly considered cost-effectiveness, that is, how many computing sites are produced determines how much computing s...
