P Systems with Tables of Rules
(Fénix Editora, 2004)
In the last time, several e®orts were made in order to remove the polarization of membranes from P systems with active membranes; the present paper is a contribution in this respect. In order to compensate the loss of ...

On the Computational Efficiency of Polarizationless Recognizer P Systems with Strong Division and Dissolution
(Fénix Editora, 2008)
Recognizer P systems with active membranes have proven to be very powerful computing devices, being able to solve NP-complete decision problems in a polynomial time. However such solutions usually exploit many powerful ...

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 ...

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 ...

Application of Weighted Fuzzy Reasoning Spiking Neural P Systems to Fault Diagnosis in Traction Power Supply Systems of High-speed Railways
(Fénix Editora, 2014)
This paper discusses the application of weighted fuzzy reasoning spiking neu- ral P systems (WFRSN P systems) to fault diagnosis in traction power supply systems (TPSSs) of China high-speed railways. Four types of neurons ...

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 ...

Looking for P Truth
(Fénix Editora, 2004)
In a general sense, Logic studies how to derive new pieces of in- formation from previous ones. In this paper we explore the analogies between P systems, where new configurations can be obtained from previous ones by using ...

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 ...

Membrane Computing Meets Artificial Intelligence: A Case Study
(Fénix Editora, 2010)
The usual way to find a solution for a NP complete problem with Membrane Computing techniques is by brute force algorithms where all the feasible solutions are generated and they are checked simultaneously by using massive ...

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 ...
