A uniform family of tissue P systems with cell division solving 3-COL in a linear time
(Elsevier, 2008)
Several examples of the efficiency of cell-like P systems regarding the solution of NPcomplete problems in polynomial time can be found in the literature(obviously, trading space for time). Recently, different new models ...

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 ...

First Steps Towards a CPU Made of Spiking Neural P Systems
(Agora University of Oradea, Romania, 2009)
We consider spiking neural P systems as devices which can be used to perform some basic arithmetic operations, namely addition, subtraction, comparison and multiplica- tion by a fixed factor. The input to these systems ...

Tissue P systems with cell division
(Agora University of Oradea, 2008)
In tissue P systems several cells (elementary membranes) communicate through symport/antiport rules, thus carrying out a computation. We add to such systems the basic feature of (cell–like) P systems with active membranes ...

On the degree of parallelism in membrane systems
(Elsevier, 2007)
In the literature, several designs of P systems might be found for performing the same task. The use of different techniques or even different P system models makes it very difficult to compare these designs. In this ...

Hierarchical clustering with Membrane Computing.
(Institute of Informatics Slovak Academy of Sciences, 2008)
In this paper we approach the problem of hierarchical clustering through membrane computing. A specific P system with external output is designed for each Boolean matrix associated with a finite set of individuals. The ...

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 ...

Complexity aspects of polarizationless membrane systems
(Springer, 2009)
We investigate polarizationless P systems with active membranes working in maximally parallel manner, which do not make use of evolution or communication rules, in order to find which features are sufficient to efficiently ...

P–Lingua 2.0: A software framework for cell–like P systems
(Agora University of Oradea, Romania, 2009)
P-Lingua is a programming language for membrane computing. It was first presented in Edinburgh, during the Ninth Workshop on Membrane Computing (WMC9). In this paper, the models, simulators and formats included in P-Lingua ...

A linear-time tissue P system based solution for the 3-coloring problem
(Elsevier, 2007)
In the literature, several examples of the efficiency of cell-like P systems regarding the solution of NPcomplete problems in polynomial time can be found (obviously, trading space for time). Recently, different new ...
