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 ...

Representative Datasets: The Perceptron Case
(Cornell University, 2019)
One of the main drawbacks of the practical use of neural networks is the long time needed in the training process. Such training process consists in an iterative change of parameters trying to minimize a loss function. ...

Depth-First Search with P Systems
(Springer, 2011)
The usual way to find a solution for an NP complete problem in Membrane Computing is by brute force algorithms. These solutions work from a theoretical point of view but they are implementable only for small instances of ...

A Cellular Sudoku Solver
(Fénix Editora, 2010)
Sudoku is a very popular puzzle which consists on placing several numbers in a squared grid according to some simple rules. In this paper we present an efficient family of P systems which solve sudoku puzzles of any order ...

An Application of Genetic Algorithms to Membrane Computing
(Fénix Editora, 2010)
The process of designing a P system in order to perform a task is a hard job. The researcher has often only an approximate idea of the design, but finding the exact description of the rules is a heavy hand-made work. In ...

Smoothing Problem in 2D Images with Tissue-like P Systems and Parallel Implementation
(Fénix Editora, 2011)
Smoothing is often used in Digital Imagery to reduce noise within an image. In this paper we present a Membrane Computing algorithm for smoothing 2D images in the framework of tissue-like P systems. The algorithm has ...

Some Notes on (Mem)Brane Computation
(Springer, 2006)
Membrane Computing and Brane Calculi are two recent computational paradigms in the framework of Natural Computing. They are based on the study of the structure and functioning of living cells as living organisms able ...

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 ...

Towards a Practical Argumentative Reasoning with Qualitative Spatial Databases
(Springer, 2003)
Classical database management can be flawed if the Knowledge database is built within a complex Knowledge Domain. We must then deal withinconsistencies and, in general, withanomalies of several types. In this paper we ...
