Computational efficiency of dissolution rules in membrane systems
(Taylor and Francis, 2006)
Trading (in polynomial time) space for time in the framework of membrane systems is not sufficient to efficiently solve computationally hard problems. On the one hand, an exponential number of objects generated in ...

A Membrane Computing View on Tumours
(2006)
In this paper we discuss about the potential usefulness of P systems as natural tools for modelling tumours. This is done both from a macroscopic point of view, by considering the tumour as a growing mass of cells, as ...

On the efficiency of cell-like and tissue-like recognizing membrane systems
(Wiley, 2009)
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 ...

On the Power of Dissolution in P Systems with Active Membranes
(Springer, 2006)
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 ...

Characterizing Tractability with Membrane Creation
(IEEE Computer Society, 2005)
This paper analyzes the role that membrane dissolution rules play in order to characterize (in the framework of recognizer P systems with membrane creation) the tractability of decision problems that is, the ef cient ...

Cell-like and Tissue-like Membrane Systems as Recognizer Devices
(Rosillo's S.L., 2006)
Most of the variants of membrane systems found in the literature are generally thought as generating devices. In this paper recognizer computational devices (cell–like and tissue–like) are presented in the framework of ...

P Systems with Active Membranes, Without Polarizations and Without Dissolution: A Characterization of P
(Springer, 2005)
We study the computational efficiency of recognizer P systems with active membranes without polarizations and without dissolution. The main result of the paper is the following: the polynomial computational complexity ...

How to express tumours using membrane systems
(ELSEVIER SCIENCE INC, 2007)
In this paper we discuss the potential usefulness of membrane systems as tools for modelling tumours. The approach is followed both from a macroscopic and a microscopic point of view. In the first case, one considers the ...

Characterizing tractability by cell-like membrane systems
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2006)
In this paper we present a polynomial complexity class in the framework of membrane computing. In this context, and using accepting transition P systems, we provide a characterization of the standard computational class P ...
