Like quantum computing or DNA computing, membrane computing is an unconventional
model of computation associated with a new computing paradigm. The field of membrane …

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 …

The present volume contains a selection of papers presented at the Seventh Workshop on
Membrane Computing, WMC7, which took place in Leiden, The Netherlands, during July 17 …

This is a comprehensive (and friendly) introduction to membrane computing (MC), meant to
offer both computer scientists and non-computer scientists an up-to-date overview of the …

Membrane systems are a new class of distributed and parallel model of computation
inspired by the subdivision of living cells into compartments delimited by membranes. Their …

In this paper we present a theory of computational complexity in the framework of membrane
computing. Polynomial complexity classes in recognizer membrane systems and capturing …

P systems with active membranes are among the central ones in membrane computing, and
they were shown to be both computationally universal (able to simulate Turing machines) …

We continue here the study of P systems with string objects processed by rewriting rules, by
investigating some questions which are classic in formal language theory: leftmost …

A membrane system (P system) is a model of computation inspired by some basic features
of the structure and behaviour of living cells. In this paper we consider systems with string …

Numerical P Systems (NPS) is a variant of P systems using real-valued quantities. It was
shown that it can successfully be applied for different real-world problems, in particular in the …
