UPSimulator: A general P system simulator

In membrane computing, researchers have designed various P systems to solve problems, for example, NP-hard problems. The research of verification methods and simulation tools for these P systems is one of the main topics in membrane computing. In this paper, we present a general-purpose P system simulator named UPSimulator for cell-like, tissue-like and neural-like P systems. UPSimulator can serve as both a simulator and a development library for P system models, which processes objects in the regions defined by membranes. UPSimulator provides a feasible solution for the simulation of hybrid P systems by supporting the complex evolutionary rules and structures in different types of P systems. (C) 2019 The Authors.
