Efficiency of Tissue P Systems with Cell Separation
(Fénix Editora, 2009)
The most investigated variants of P systems in the last years are cell-like models, especially in terms of efficiency. Recently, different new models of tissue-like (symport/antiport) P systems have received important ...

Dynamical Probabilistic P Systems: Definitions and Applications
(Fénix Editora, 2005)
We introduce dynamical probabilistic P systems, a variant where probabilities associated to the rules change during the evolution of the system, as a new approach to the analysis and simulation of the behavior of complex ...

Further Remarks on P Systems with Active Membranes, Separation, Merging, and Release Rules
(Fénix Editora, 2004)
The P systems are a class of distributed parallel computing devices of a biochemical type. In this note, we show that by using membrane separation to obtain exponential workspace, SAT problem can be solved in linear ...

On the Efficiency of Spiking Neural P Systems
(2006)
Spiking neural P systems were recently introduced in and proved to be Turing complete as number computing devices. In this paper we show that these systems are also computationally efficient. Specifically, we present a ...

Spiking Neural P Systems and Modularization of Complex Networks from Cortical Neural Network to Social Networks
(Fénix Editora, 2009)
An idea of modularization of complex networks (from cortial neural net, Internet computer network, to market and social networks) is explained and some its topic motivations are presented. Then some known modularization ...

Solving 3-COL with Tissue P Systems
(Fénix Editora, 2006)
In the literature, several examples of the efficiency of cell-like P systems in order to solve NP-complete problems in polynomial time can be found. Recently, various new models of tissue-like P systems have received ...

New Proposals for the Formalization of Membrane Proteins
(Fénix Editora, 2004)
This paper presents three new proposals to take advantage, in the framework of P systems, from proteins acting in bacteria. One attempt aims to focus on the transport protein that act as a logic AND gate at the cell membrane. ...

P Systems with Symport/Antiport of Rules
(Fénix Editora, 2004)
Moving \instructions" instead of \data", using transport mecha- nisms inspired by biology { this could represent, shortly, the basic idea of the computing device presented in this paper. Speci¯cally, we propose a new ...
