A Computational Complexity Theory in Membrane Computing
(Springer, 2010)
In this paper, a computational complexity theory within the framework of Membrane Computing is introduced. Polynomial complexity classes associated with di erent models of cell-like and tissue-like membrane systems are ...

Verifying a P system generating squares
(Romanian Academy, Section for Information Science and Technology, 2002)
In [1], an example of a P system generating exactly all the squares of natural numbers greater than 1 is given. Nevertheless, only an informal reasoning of this result is presented. In this paper we study a similar P ...

Membrane Computing Schema Based on String Insertions
(Fénix Editora, 2007)
In this note we introduce the notion of a membrane computing schema for string objects. We propose a computing schema for a membrane network (i.e., tissue-like membrane system) where each membrane performs unique type ...

Un entorno para la experimentación virtual con modelos computacionales basados en sistemas P
(2015-02-02)
** Introducción Desde el principio de los tiempos, el Hombre se ha visto abocado a resolver problemas. En un principio problemas muy concretos, como huir de un peligro inminente, buscar un alimento en un momento dado o ...

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 ...

On P Systems as a Modelling Tool for Biological Systems
(Springer, 2006)
We introduce a variant of P systems where rules have associated a real number providing a measure for the “intrinsic reactivity”of the rule and roughly corresponding to the kinetic coefficient which, in bio-chemistry, ...

Tissue P Systems with Protein on Cells
(IOS Press, 2016)
Tissue P systems are a class of distributed parallel computing devices inspired by biochemical interactions between cells in a tissue-like arrangement, where objects can be exchanged by means of communication channels. ...

Modeling Logic Gene Networks by Means of Probabilistic Dynamic P Systems
(Old City Publishing, 2013)
Gene regulatory networks are useful models for biologists to understand the interactions among genes in living organisms. In this work, we consider a special class of gene regulatory networks, called logical networks, ...
