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 ...

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 ...

Simulation of P systems with active membranes on CUDA
(Oxford University Press, 2010)
P systems or Membrane Systems provide a high-level computational modelling framework that combines the structure and dynamic aspects of biological systems in a relevant and understandable way. They are inherently parallel ...

Spiking Neural P Systems: A Short Introduction and New Normal Forms
(Editorial Academiei, 2012)
Spiking neural P systems are a class of P systems inspired from the way the neurons communicate with each other by means of electrical impulses (called \spikes"). In the few years since this model was introduced, many ...

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 ...

Tissue Simulator: A Graphical Tool for Tissue P Systems
(MTA SZTAKI, 2007)
Recently, different new models of tissue-like P systems have received important attention from the scientific community. This paper is focused in a concrete model: recognizing tissue P system with cell division. A software ...

Towards Probabilistic Model Checking on P Systems Using PRISM
(Springer, 2006)
This paper presents the use of P systems and π-calculus to model interacting molecular entities and how they are translated into a probabilistic and symbolic model checker called PRISM.
