On the degree of parallelism in membrane systems
(Elsevier, 2007)
In the literature, several designs of P systems might be found for performing the same task. The use of different techniques or even different P system models makes it very difficult to compare these designs. In this ...

A P-Lingua based Simulator for Tissue P Systems with Cell Separation
(Romanian Academy, Section for Information Science and Technology, 2014)
Tissue P systems are one of the currently active research topics within the field of Membrane Computing. In particular, their computational efficiency is being investigated in the case when the number of cells can grow ...

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 ...

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 ...

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 ...

Modeling Logic Gene Networks by Means of Probabilistic Dynamic P Systems
(Old City Publishing, 2013)
Gene regulatory networks are useful models for biologists to understand the interactions among genes in living organisms. In this work, we consider a special class of gene regulatory networks, called logical networks, ...

Spiking Neural P systems with several types of spikes
(Agora University of Oradea, 2011)
With a motivation related to gene expression, where enzymes act in series, somewhat similar to the train spikes traveling along the axons of neurons, we consider an extension of spiking neural P systems, where several ...

Solving Common Algorithmic Problem by Recognizer Tissue P Systems
(Romanian Academy, 2012)
Common Algorithmic Problem is an optimization problem, which has the nice property that several other NP-complete problems can be reduced to it in linear time. In this work, we deal with its decision version in the ...

A computational modeling for real ecosystems based on P systems
(Springer, 2011)
In this paper, a P systems based general framework for modeling ecosystems dynamics is presented. Particularly, ecosystems are specified by means of multienvironment P systems composed of a finite number of environments, ...
