A Fast Solution to the Partition Problem by Using Tissue-Like P Systems
(IEEE Computer Society, 2008)
Tissue-like P systems with cell division is a computing model in the framework of membrane computing based on the intercellular communication and cooperation between neurons. In such a model, the structure of the devices ...

Characterizing the Aperiodicity of Irreducible Markov Chains by Using P Systems
(Fénix Editora, 2009)
It is well known that any irreducible and aperiodic Markov chain has exactly one stationary distribution, and for any arbitrary initial distribution, the sequence of distributions at time n converges to the stationary ...

A Membrane Computing View on Tumours
(2006)
In this paper we discuss about the potential usefulness of P systems as natural tools for modelling tumours. This is done both from a macroscopic point of view, by considering the tumour as a growing mass of cells, as ...

Hierarchical clustering with Membrane Computing.
(Institute of Informatics Slovak Academy of Sciences, 2008)
In this paper we approach the problem of hierarchical clustering through membrane computing. A specific P system with external output is designed for each Boolean matrix associated with a finite set of individuals. The ...

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 ...

Computing with Spiking Neural P Systems: Traces and Small Universal Systems
(Springer, 2006)
Recently, the idea of spiking neurons and thus of computing by spiking was incorporated into membrane computing, and so-called spiking neural P systems (abbreviated SN P systems) were introduced. Very shortly, in these ...

Modeling Ecosystems Using P Systems: The Bearded Vulture, a Case Study
(Springer, 2009)
The Bearded Vulture (Gypaetus barbatus) is an endangered species in Europe that feeds almost exclusively on bone remains of wild and domestic ungulates. In this paper, we present a model of an ecosystem related to the ...

Complexity aspects of polarizationless membrane systems
(Springer, 2009)
We investigate polarizationless P systems with active membranes working in maximally parallel manner, which do not make use of evolution or communication rules, in order to find which features are sufficient to efficiently ...

P systems-based Modelling of Cellular Signalling Pathways
(2006)
Cellular signalling pathways are fundamental to the control and regulation of cell behaviour. Understanding the biosignalling network functions are crucial for studying di erent diseases and for designing e ective ...

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 ...
