UPSimulator

UPSimulator is an universal and high performance simulator for membrane computing. Now, we have supported most features of cell-like P system & tissue-like P system, and basic support for neural-like P system. Visit https://github.com/quancs/UPSimulator/releases to download the latest version.
Please notice that: What you simulate in UPSimulator is what you use. We are not going to make any assumptions about the models you want to simulate, because we will never know that what kind of new P system will be proposed in the future, and what kind of new concepts the new P system will have. If you want to simulate one kind of P system whose concepts ( conditions and results and tunnels ) have already been supported by UPSimulator in Table 2, please just combine the conditions, results and tunnels to make it.

The main differences between PLingua and UPSimulator

Aspect	PLingua	UPSimulator
How to support models	Support models directly (Table 2)	Support models by combing different concepts (Table 1)
Supporting new models	Hard. Need to recode almost everything for the new model.	Easy. If the concepts in the new model exist in the old models, the new model is naturally supported. If not, only few functions need to be implemented for the new concepts in the new model.
User interfaces	Command line	Graphical interfaces
Format	Input: PLingua language format or other format Output: text format	Input: UPLanguage Output: UPLanguage
