(Tissue) P Systems Using Non-cooperative Rules Without Halting Conditions
(Fénix Editora, 2008)
We consider (tissue) P systems using non-cooperative rules, but considering computations without halting conditions. As results of a computation we take the contents of a specified output membrane/cell in each derivation ...

Small Computationally Complete Symport/Antiport P Systems
(Fénix Editora, 2006)
It is known that P systems with symport/antiport rules simulate the register machines, i.e., they are computationally complete. Hence, due to the existence of universal register machines, there exist computationally ...

Some Notes on the Interplay Between P Systems and Chemotaxis in Bacteria
(Fénix Editora, 2006)
We describe some chemotactic behaviors of bacteria, that is, their movement response to changes in the environment, and the underlying molecular mechanisms. We outline how such processes could be linked to membrane ...

A First Model for Hebbian Learning with Spiking Neural P Systems
(Fénix Editora, 2008)
Spiking neural P systems and artificial neural networks are computational devices which share a biological inspiration based on the transmission of information among neurons. In this paper we present a first model for ...

A Note on Complexity Measures for Probabilistic P Systems
(Fénix Editora, 2004)
In this paper we present a first approach to the definition of different entropy measures for probabilistic P systems in order to obtain some quantitative parameters showing how complex the evolution of a P system is. To ...

A Note on P Systems with Activators
(Fénix Editora, 2004)
The usual assumption in P systems behavior is that of maximal parallelism, however in living cells it is not the case because they have a limited number of enzymes. The aim of this paper is to try to merge these ideas ...

Testing Einstein’s Formula on Brownian Motion Using Membrane Computing
(Fénix Editora, 2008)
Brownian motion refers to erratic movements of small particles of solid matter suspended in a fluid and it is the basis of the development of many fractals found in Nature. In this paper we use the Membrane Computing ...

P-Lingua: A Programming Language for Membrane Computing
(Fénix Editora, 2008)
Software development for cellular computing has already been addressed, yielding a first generation of applications. In this paper, we develop a new programming language: P-Lingua. Furthermore, we present a simulator for ...

Small Universal Antiport P Systems and Universal Multiset Grammars
(Fénix Editora, 2006)
Based on the construction of a universal register machine we construct a universal antiport P system working with 31 rules in the maximally parallel mode in one membrane, and a universal antiport P system with forbidden ...

A Quantum-Inspired Evolutionary Algorithm Based on P systems for a Class of Combinatorial Optimization
(Fénix Editora, 2008)
This paper introduces an evolutionary algorithm which uses the concepts and principles of the quantum-inspired evolutionary approach and the hierarchical arrangement of the compartments of a P system. The P system framework ...
