On the power of dissolution in p systems with active membranes

In this paper we study membrane dissolution rules in the framework of P systems with active membranes but without using electrical charges. More precisely, we prove that the polynomial computational complexity class associated with the class of recognizer P systems with active membranes, without polarizations and without dissolution coincides with the standard complexity class P. Furthermore, we demonstrate that if we consider dissolution rules, then the resulting complexity class contains the class NP.In this paper we study membrane dissolution rules in the framework of P systems with active membranes but without using electrical charges.

On the efficiency of cell-like and tissue-like recognizing membrane systems

Cell‐like recognizing membrane systems are computational devices in the framework of membrane computing inspired from the structure of living cells, where biological membranes are arranged hierarchically. In this paper tissue‐like recognizing membrane systems are presented. The idea is to consider that membranes are placed in the nodes of a graph, mimicking the cell intercommunication in tissues.
