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–Lingua 2.0: A software framework for cell–like P systems
(Agora University of Oradea, Romania, 2009)
P-Lingua is a programming language for membrane computing. It was first presented in Edinburgh, during the Ninth Workshop on Membrane Computing (WMC9). In this paper, the models, simulators and formats included in P-Lingua ...

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 Tissue P Systems Based Uniform Solution to Tripartite Matching Problem
(IOS Press, 2011)
A tissue P system with cell division is a computing model which has two basic features: intercellular communication and the ability of cell division. The ability of cell division allows us to obtain an exponential amount ...

3-Col problem modelling using simple kernel P systems
(Taylor and Francis, 2013)
This paper presents the newly introduced class of (simple) kernel P systems ((s)kP systems) and investigates through a 3-colouring problem case study the expressive power and efficiency of kernel P systems. It describes ...

Comparing simulation algorithms for multienvironment probabilistic P systems over a standard virtual ecosystem
(Springer, 2012)
Membrane Computing has recently proved to be a suitable framework for addressing the modelling of dynamical biological systems in general, and ecosystems in particular. Due to the inherent randomness and uncertainty in ...

The role of the direction in tissue P systems with cell separation
(Institut für Informatik, Justus-Liebig-Universität Giessen, 2014)
Tissue P systems with cell separation where the communication among cells is performed by means of symport and antiport rules are able to efficiently solve computationally hard problems in a feasible time by a space-time ...
