Gene Selection in Cancer Classification using PSO/SVM and GA/SVM Hybrid Algorithms
(IEEE Computer Society, 2007)
In this work we compare the use of a Particle Swarm Optimization (PSO) and a Genetic Algorithm (GA) (both augmented with Support Vector Machines SVM) for the classification of high dimensional Microarray Data. ...

Hierarchical clustering with Membrane Computing.
(Institute of Informatics Slovak Academy of Sciences, 2008)
In this paper we approach the problem of hierarchical clustering through membrane computing. A specific P system with external output is designed for each Boolean matrix associated with a finite set of individuals. The ...

Performing Arithmetic Operations with Spiking Neural P Systems
(Fénix Editora, 2009)
We consider spiking neural P systems as devices which can be used to perform some basic arithmetic operations, namely addition, subtraction, comparison and multiplication by a fixed factor. The input to these systems are ...

On the efficiency of cell-like and tissue-like recognizing membrane systems
(Wiley, 2009)
Cell-like recognizing membrane systems are computational devices in the framework of membrane computing inspired from the structure of living cells, where biological membranes are arranged hierarchically. In this paper ...

Computing with Spiking Neural P Systems: Traces and Small Universal Systems
(Springer, 2006)
Recently, the idea of spiking neurons and thus of computing by spiking was incorporated into membrane computing, and so-called spiking neural P systems (abbreviated SN P systems) were introduced. Very shortly, in these ...

Modeling Ecosystems Using P Systems: The Bearded Vulture, a Case Study
(Springer, 2009)
The Bearded Vulture (Gypaetus barbatus) is an endangered species in Europe that feeds almost exclusively on bone remains of wild and domestic ungulates. In this paper, we present a model of an ecosystem related to the ...

Complexity aspects of polarizationless membrane systems
(Springer, 2009)
We investigate polarizationless P systems with active membranes working in maximally parallel manner, which do not make use of evolution or communication rules, in order to find which features are sufficient to efficiently ...

P systems-based Modelling of Cellular Signalling Pathways
(2006)
Cellular signalling pathways are fundamental to the control and regulation of cell behaviour. Understanding the biosignalling network functions are crucial for studying di erent diseases and for designing e ective ...

P–Lingua 2.0: A software framework for cell–like P systems
(Agora University of Oradea, Romania, 2009)
P-Lingua is a programming language for membrane computing. It was first presented in Edinburgh, during the Ninth Workshop on Membrane Computing (WMC9). In this paper, the models, simulators and formats included in P-Lingua ...

A linear-time tissue P system based solution for the 3-coloring problem
(Elsevier, 2007)
In the literature, several examples of the efficiency of cell-like P systems regarding the solution of NPcomplete problems in polynomial time can be found (obviously, trading space for time). Recently, different new ...
