Towards a Programming Language in Cellular Computing
(Fénix Editora, 2004)
Several solutions to hard numerical problems using P systems have been presented recently, and strong similarities in their designs have been no- ticed. In this paper we present a new solution, an e®ective one to the ...

Hybrid Networks of Evolutionary Processors
(Springer, 2003)
A hybrid network of evolutionary processors consists of several processors which are placed in nodes of a virtual graph and can perform one simple operation only on the words existing in that node in accordance with ...

A Prolog Simulator for Deterministic P Systems with Active Membranes
(Springer, 2004)
In this paper we propose a new way to represent P systems with active membranes based on Logic Programming techniques. This representation allows us to express the set of rules and the configuration of the P system in ...

A Modeling Approach Based on P Systems with Bounded Parallelism
(Springer, 2006)
This paper presents a general framework for modelling with membrane systems that is based on a computational paradigm where rules have associated a finite set of attributes and a corresponding function. Attributes and ...

The P Versus NP Problem Through Cellular Computing with Membranes
(Springer, 2004)
We study the P versus NP problem through membrane systems. Language accepting P systems are introduced as a framework allowing us to obtain a characterization of the P = NP relation by the polynomial time unsolvability ...

A uniform solution to SAT using membrane creation
(Elsevier, 2007)
In living cells, new membranes are produced basically through two processes: mitosis and autopoiesis. These two processes have inspired two variants of cell-like membrane systems, namely P systems with active membranes ...

Weak Metrics on Configurations of a P System
(Fénix Editora, 2004)
The evolution of a P system generates a tree of computation po- tentially in¯nite where it is very difficult to set the degree of closeness between two configurations. The problem is specially hard if we want to quantify ...

A Simulator for Confluent P Systems
(Fénix Editora, 2005)
Software simulators for P system are nowadays the main tool to carry out experiments in the field of Membrane Computing. Although the simulation of a P system is a quite complex task, current simulators have been ...

Modelling EGFR signalling cascade using continuous membrane systems
(2005)
The complexity of networks of biological signalling pathways is such that the development of simplifying models is essential in trying to understand the wide-ranging cellular responses they can generate. In this paper ...
