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 ...

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 ...

Operadores de generalización para el aprendizaje clausal
(2002)
"En esta memoria hemos estudiado los procesos de generalización, el paso de lo particular a lo general, cuando la información está expresada en lenguaje clausal. Para ello hemos definido unos operadores adaptados a los ...

Graphical Modeling of Higher Plants Using P Systems
(Springer, 2006)
L systems have been widely used to model and graphically represent the growth of higher plants [20]. In this paper we continue developing the framework introduced in [21], which make use of the topology of membrane ...

Computing Backwards with P Systems
(Fénix Editora, 2009)
Searching all the configurations C′ such that produce a given configuration C, or, in other words, computing backwards in Membrane Computing is an extremely hard task. The current approximations are based in heavy hand-made ...

Fractals and P Systems
(Fénix Editora, 2006)
In this paper we show that the massive parallelism, the synchronous appli- cation of the rules, and the discrete nature of their computation, among other features, lead us to consider P systems as natural tools for dealing ...

Looking for P Truth
(Fénix Editora, 2004)
In a general sense, Logic studies how to derive new pieces of in- formation from previous ones. In this paper we explore the analogies between P systems, where new configurations can be obtained from previous ones by using ...
Tesis Doctoral
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 ...
