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 ...

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 ...

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 ...
Capítulo de Libro
Available Membrane Computing Software
(Springer, 2006)
The simulation of a P system with current computers is a quite com-plex task. P systems are intrinsically nondeterministic computational devices and therefore their computation trees are di±cult to store and handle with ...

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 ...

A Prolog Simulator for Deterministic P Systems with Active Membranes
(Springer, 2004)
In this paper we propose a new way to represent P systems with active membranes based on Logic Programming techniques. This representation allows us to express the set of rules and the configuration of the P system in ...

A uniform solution to SAT using membrane creation
(Elsevier, 2007)
In living cells, new membranes are produced basically through two processes: mitosis and autopoiesis. These two processes have inspired two variants of cell-like membrane systems, namely P systems with active membranes ...
