Implementing in Prolog an Effective Cellular Solution to the Knapsack Problem
(Springer, 2004)
In this paper we present an implementation in Prolog of an effective solution to the Knapsack problem via a family of deterministic P systems with active membranes using 2-division.

Exploring Computation Trees Associated with P Systems
(Springer, 2005)
Usually, the evolution of a P system generates a computation tree too large to be efficiently handled with present–day computers; moreover, different branches in this tree may differ significantly from a computational ...

Available Membrane Computing Software
(Springer, 2006)
The simulation of a P system with current computers is a quite com-plex task. P systems are intrinsically nondeterministic computational devices and therefore their computation trees are di±cult to store and handle with ...

On the Power of Dissolution in P Systems with Active Membranes
(Springer, 2006)
In this paper we study membrane dissolution rules in the framework of P systems with active membranes but without using electrical charges. More precisely, we prove that the polynomial computational complexity class ...

Characterizing Tractability with Membrane Creation
(IEEE Computer Society, 2005)
This paper analyzes the role that membrane dissolution rules play in order to characterize (in the framework of recognizer P systems with membrane creation) the tractability of decision problems that is, the ef cient ...

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 ...

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 ...

P Systems with Active Membranes, Without Polarizations and Without Dissolution: A Characterization of P
(Springer, 2005)
We study the computational efficiency of recognizer P systems with active membranes without polarizations and without dissolution. The main result of the paper is the following: the polynomial computational complexity ...

On Descriptive Complexity of P Systems
(Springer, 2005)
In this paper we address the problem of describing the complexity of the evolution of a P system. This issue is is specially hard in the case of P systems with active membranes, where the number of steps of a computation ...
