We consider tissue P systems working on vesicles of multisets with the very simple operations of insertion, deletion, and substitution of single objects. With the whole multiset being enclosed in a vesicle, sending it to a target cell can be indicate

Catalytic P systems are among the first variants of membrane systems ever considered in this area. This variant of systems also features some prominent computational complexity questions, and in particular the problem of using only one catalyst in th

SymPy is an open source computer algebra system written in pure Python. It is built with a focus on extensibility and ease of use, through both interactive and programmatic applications. These characteristics have led SymPy to become a popular symbol

International audience; In this paper we consider prescribed sets of rules working on several objects either in parallel – in this case the rules have to take different objects – or else sequentially in any order – in this case several rules ma

P systems with limited number of objects

Autor: Artiom Alhazov, Sergiu Ivanov, Rudolf Freund

Publikováno v: Journal of Membrane Computing. 3:1-9

P systems are a model of compartmentalized multiset rewriting inspired by the structure of living cells and the way they function. In this paper, we focus of a variant in P systems in which membranes have limited capacity, i.e., the number of objects
