Descriptional Complexity of Tissue-Like P Systems with Cell Division
(Springer, 2009)
In this paper we address the problem of describing the complexity of the evolution of a tissue-like P system with cell division. In the computations of such systems the number of (parallel) steps is not sufficient to ...

Particle Swarm Hybridized with Differential Evolution: Black-Box Optimization Benchmarking for Noisy Functions
(ACM Digital Library, 2009)
In this work we evaluate a Particle Swarm Optimizer hy- bridized with Di®erential Evolution and apply it to the Black- Box Optimization Benchmarking for noisy functions (BBOB 2009). We have performed the complete procedure ...

Computing Backwards with P Systems
(Fénix Editora, 2009)
Searching all the configurations C′ such that produce a given configuration C, or, in other words, computing backwards in Membrane Computing is an extremely hard task. The current approximations are based in heavy hand-made ...

A First Attempt to Model Notch Signalling by Means of P Systems
(Universidad de Sevilla, Departamento de Ciencias de la Computación e Inteligencia Artificial, 2009)
During mammalian central nervous system development, an enormous variety of cell types are generated. This cell diversity is due in part to asymmetrical cell division. Indeed, in some sense Notch signals link the fate ...

A massively parallel framework using P systems and GPUs
(National Center for Supercomputing Applications at the University of Illinois, 2009)
Since CUDA programing model appeared on the general purpose computations, the developers can extract all the power contained in GPUs (Graphics Processing Unit) across many computational domains. Among these domains, P ...

SMPSO: A new PSO-based metaheuristic for multi-objective optimization
(IEEE Computer Society, 2009)
In this work, we present a new multi-objective particle swarm optimization algorithm (PSO) characterized by the use of a strategy to limit the velocity of the particles. The proposed approach, called Speed-constrained ...

Simulating Active Membrane Systems Using GPUs
(Universidad de Sevilla, Departamento de Ciencias de la Computación e Inteligencia Artificial, 2009)
Software development for cellular computing is growing up yielding new applications. In this paper, we describe a simulator for the class of recognizer P systems with active membranes, which exploits the massively parallel ...

Multi-Objective Particle Swarm Optimizers: An Experimental Comparison
(Springer, 2009)
Particle Swarm Optimization (PSO) has received increasing attention in the optimization research community since its first appearance in the mid-1990s. Regarding multi-objective optimization, a considerable number of ...

Noiseless Functions Black-Box Optimization: Evaluation of a Hybrid Particle Swarm with Differential Operators
(ACM Digital Library, 2009)
In this work we evaluate a Particle Swarm Optimizer hy- bridized with Di®erential Evolution and apply it to the Black- Box Optimization Benchmarking for noiseless functions (BBOB 2009). We have performed the complete ...

Membrane dissolution and division in P
(Springer, 2009)
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 systems. In particular we examine systems ...
