P–Lingua 2.0: A software framework for cell–like P systems

Abstract

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 in version 2.0 are explained. We focus on the stochastic model, associated simulators and updated features. Finally, we present one of the first applications based on PLingua: a tool for describing and simulating ecosystems.

A P System Based Model of an Ecosystem of Some Scavenger Birds

“…The software tool used for the purposes of this paper is based on P-Lingua 2.0 [4]. P-Lingua is a new programming language able to define P systems of different types (from now on, frameworks).…”

“…It has been developed simulator of the model written in JAVA by using the specification language P-Lingua [4]. This simulator allows us to experimentally validate the model as well as study the ecosystem dynamics under different initial conditions.…”

“…Next section shows a formal framework to model ecosystems by means of probabilistic P systems, and a P system modelling of the above mentioned ecosystem is presented. In Section 3, we experimentally validate the model presented in this paper by using a P-lingua simulator [4] and we also compare it to the one presented in [1].…”

Simulation of P Systems with Active Membranes on CUDA

“…The simulator is executed into two stages: selection stage and execution stage. This is based on the simulator for P systems with active membranes developed in PLinguaCore by I. Pérez-Hurtado et al [8]. The selection stage consists of the search for the rules to be executed in each membrane.…”

“…In this work, we use the new version, P-Lingua 2.0 [8], to generate a binary file that our simulator can use as input. This binary file is easy-to-read by a C++ program, containing all the information of the P system (Alphabet, Labels, Rules, .…”
