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 ...

Computing Homology Groups in Binary 2D Imagery by Tissue-like P Systems
(Romanian Academy, Section for Information Science and Technology, 2010)
We present a new solution for the Homology Groups of Binary 2D Image (HGB2I) Problem by using Membrane Computing techniques. This is a classical problem in Homology Theory which tries to calculate the number of connected ...

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 ...

Some Notes on (Mem)Brane Computation
(Springer, 2006)
Membrane Computing and Brane Calculi are two recent computational paradigms in the framework of Natural Computing. They are based on the study of the structure and functioning of living cells as living organisms able ...

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 ...

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 ...
