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 ...

Counting Cells with Tissue-like P Systems
(Fénix Editora, 2012)
Counting the number of cells obtained in an experiment is crucial in many areas in Biology. Nonetheless, this is usually performed by hand by the researcher due the intrinsic difficulty of the task. In this paper, we ...

An Optimal Frontier of the Efficiency of Tissue P Systems with Cell Division
(Fénix Editora, 2012)
In the framework of tissue P systems with cell division, the length of communication rules provides a frontier for the tractability of decision problems. On the one hand, the limitation on the efficiency of tissue P ...

Improving the Efficiency of Tissue P Systems with Cell Separation
(Fénix Editora, 2012)
Cell fission process consists of the division of a cell into two new cells such that the contents of the initial cell is distributed between the newly created cells. This process is modelled by a new kind of cell separation ...

Universal P Systems: One Catalyst Can Be Suficient
(Fénix Editora, 2013)
Whether P systems with only one catalyst can already be universal, is still an open problem. Here we establish universality (computational completeness) by using speci c variants of additional control mechanisms. At each ...

Spiking Neural P Systems with Several Types of Spikes
(Fénix Editora, 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 ...

Polarizationless P Systems with Active Membranes Working in the Minimally Parallel Mode
(Fénix Editora, 2007)
We investigate the computing power and the efficiency of P systems with active membranes without polarizations, working in the minimally parallel mode. We prove that such systems are computationally complete and able to ...

A P System Modeling an Ecosystem Related to the Bearded Vulture
(Fénix Editora, 2008)
The Bearded Vulture is one of the rarest raptors in Europe and it is an endangered species. In this paper, we present a model of an ecosystem related with the Bearded Vulture which is located in the Catalan Pyrenees, by ...

Studying the Chlorophyll Fluorescence in Cyanobacteria with Membrane Computing Techniques
(Fénix Editora, 2013)
In this paper, we report a pioneer study of the decrease in chlorophyll uorescence produced by the reduction of MTT (a dimethyl thiazolyl diphenyl tetrazolium salt) monitored using an epi uorescence microscope coupled ...

A Membrane-Inspired Evolutionary Algorithm with a Population P System and its Application to Distribution System Recon guration
(Fénix Editora, 2012)
This paper develops a membrane-inspired evolutionary algorithm, PSMA, which is designed by using a population P system and a quantum-inspired evolutionary algorithm (QIEA). We use a population P system with three cells ...
