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

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 P- Lingua: a tool for describing and simulating ecosystems. Ministerio de Educación y Ciencia TIN2006–13425 Junta de Andalucía P08-TIC-04200
