Descriptional Complexity of Tissue-Like P Systems with Cell Division
(Springer, 2009)
In this paper we address the problem of describing the complexity of the evolution of a tissue-like P system with cell division. In the computations of such systems the number of (parallel) steps is not sufficient to ...

P Systems with Tables of Rules
(Fénix Editora, 2004)
In the last time, several e®orts were made in order to remove the polarization of membranes from P systems with active membranes; the present paper is a contribution in this respect. In order to compensate the loss of ...

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 ...

Programación celular resolución eficiente de problemas numéricos NP-completos
(2004)
Esta memoria está estructurada en capítulos cuyos contenidos pasamos a describir sucintamente. En el Capítulo 1 se hace una breve introducción histórica de la Teoría de la Computabilidad, analizándose las limitaciones ...

Tissue P Systems with Cell Division
(Fénix Editora, 2004)
In tissue P systems several cells (elementary membranes) commu- nicate through symport/antiport rules, thus carrying out a computation. We add to such systems the basic feature of (cell) P systems with active membranes { ...

Solving the Partition Problem by Using Tissue-like P Systems with Cell Division
(Fénix Editora, 2008)
Tissue-like P systems with cell division is a computing model in the framework of Membrane Computing that shares with the spiking neural P system model a similar biological inspiration. Namely, both models are based on ...

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 ...

Membrane dissolution and division in P
(Springer, 2009)
Membrane systems with dividing and dissolving membranes are known to solve PSPACE problems in polynomial time. However, we give a P upperbound on an important restriction of such systems. In particular we examine systems ...

Solving the Subset-Sum Problem by P Systems with Active Membranes
(Springer, 2005)
We present the first membrance computing solution to the Subset-Sum problem using a family of deterministic P systems with active membranes. We do not use priority among rules, membrane dissolution nor cooperation; it ...
