The computational power of membrane systems under tight uniformity conditions
We apply techniques from complexity theory to a model of biological cellular membranes known as membrane systems or P-systems. Like Boolean circuits, membrane systems are defined ...

A guide to membrane computing
Membrane systems are models of computation which are inspired by some basic features of biological membranes. In a membrane system multisets of objects are placed in the compartme...

An approach to membrane computing under inexactitude
In this paper we introduce a fuzzy version of symport/antiport membrane systems. Our fuzzy membrane systems handle possibly inexact copies of reactives and their rules are endowed...

(Tissue) P Systems with Unit Rules and Energy Assigned to Membranes
We introduce a new variant of membrane systems where the rules are directly assigned to membranes and, moreover, every membrane carries an energy value that can be changed during a...

Modeling and Simulating Biological Processes with Stochastic Multiset Rewriting
ed Abstract Membrane systems are models of computation inspired by the structure and the function of biological cells. The model was introduced in 1998 by Gh. Paun and since then m...

Replicative - Distribution Rules in P Systems with Active Membranes
Abstract. P systems (known also as membrane systems) are biologically motivated theoretical models of distributed and parallel computing. The two most interesting questions in the ...

Active Membrane Systems Without Charges and Using Only Symmetric Elementary Division Characterise P
In this paper we introduce a variant of membrane systems with elementary division and without charges. We allow only elementary division where the resulting membranes are identical...

Membrane Dissolution and Division in P
Membrane systems with dividing and dissolving membranes are known to solve PSPACE problems in polynomial time. However, we give a P upperbound on an important restriction of such s...
