摘要: In the framework of recognizer cell–like membrane systems it is well known that construction exponential number objects in polynomial time not enough to efficiently solve NP–complete problems. Nonetheless, may be sufficient create an membranes time. In this paper, we study computational efficiency tissue P with communication (symport/antiport) rules and division rules. Some results have been already obtained direction: (a) using making no use rules, only tractable problems can solved; (b) length three solved. show plays a relevant role from point view for kind systems.
