Weak Metrics on Configurations of a P System
(Fénix Editora, 2004)
The evolution of a P system generates a tree of computation po- tentially in¯nite where it is very difficult to set the degree of closeness between two configurations. The problem is specially hard if we want to quantify ...

A syntax for semantics in P-Lingua
(Escuela Técnica Superior de Ingeniería Informática, Universidad de Sevilla, 2019)
P-Lingua is a software framework for Membrane Computing, it includes a programming language, also called P-Lingua, for writting P system de nitions using a syntax close to standard scienti c notation. The rst line of a ...

A Simulator for Confluent P Systems
(Fénix Editora, 2005)
Software simulators for P system are nowadays the main tool to carry out experiments in the field of Membrane Computing. Although the simulation of a P system is a quite complex task, current simulators have been ...

Limits on P Systems with Proteins and Without Division
(Universidad de Sevilla, Escuela Técnica Superior de Ingeniería Informática, 2018)
In the field of Membrane Computing, computational complexity theory has been widely studied trying to nd frontiers of efficiency by means of syntactic or semantical ingredients. The objective of this is to nd two kinds ...

A Linear Solution for Subset Sum Problem with Tissue P Systems with Cell Division
(Fénix Editora, 2007)
Tissue P systems are a computing model in the framework of Membrane Computing where the tree-like membrane structure is replaced by a general graph. Recently, it has been shown that endowing these P systems with cell ...

Editing Configurations of P Systems
(Fénix Editora, 2005)
This paper proposes and preliminarily investigates the possibility of transforming a configuration (membrane structure and multisets of symbol-objects present in the compartments of this membrane structure) of a P system ...

DCBA: Simulating Population Dynamics P Systems with Proportional Object Distribution
(Fénix Editora, 2012)
Population Dynamics P systems refer to a formal framework for ecological modelling. The semantics of the model associates probabilities to rules, but at the same time, the model is based on P systems, so the rules are ...

Tissue-like P Systems Without Environment
(Fénix Editora, 2010)
In this paper we present a tissue-like P systems model with cell division the environment has been replaced by an extra cell. In such model, we present a uniform family of recognizer P systems which solves the Subset Sum ...

Kernel P Systems - Version 1
(Fénix Editora, 2013)
A basic P system, called kernel P system4 (kP system for short), combining features of di erent P systems introduced and studied so far is de ned and discussed. The structure of such systems is de ned as a dynamic graph, ...

Extending SNP Systems Asynchronous Simulation Modes in P-Lingua
(Fénix Editora, 2014)
Spiking neural P systems (SN P systems for short) is a developing field within the P systems world. Inspired by the neurophysiological structure of the brain, these systems have been subjected to many extensions in recent ...
