P-Lingua

From The P-Lingua Website

P-Lingua is a programming language for membrane computing which aims to be a standard to define P systems. It and its associated tools have been developed by members of the Research Group on Natural Computing, at the University of Sevilla, Spain.

The P-Lingua programmes define P systems in an easy-to-learn, modular and parametric way. In this sense, it is possible to define a family of P systems with the use of parameters.

P-Lingua is able to define P systems within a set of supported models. Check the P-Lingua format to learn more about the syntax of the language.
