One of the purposes of this thesis is to study the gravitomagnetic effects. These effects are derived by the analogy between Coulomb’s law and Newton’s gravitation law. There is a relationship between Maxwell’s equ...

Traditionally in Genetic Algorithms, the mutation probability parameter maintains a constant value during the search. However, an important difficulty is to determine a priori which probability value is the best suited f...

This article presents the application of a Parallel Evolutionary Algorithm to solve the Minimum Interference Frequency Assignment Problem (MI-FAP). This is a capital problem in the mobile telecommunication field, which p...

In this paper we describe a computer system that calculates allocation to claims according to two kinds of bankruptcy rules. The first kind implemented are those whose results corresponds to the classical solutions of ga...

In this paper, we present a modified version of an algorithm inspired on the T-Cell model, it is an artificial immune system (AIS), based on the process that suffers the T-Cell. The proposed algorithm is called TCEC (T-C...

Genetic algorithms (GAs) are stochastic adaptive algorithms whose search method is based on simulation of natural genetic inheritance and Darwinian strive for survival. They can be used to find approximate solutions to n...

The Projected Aggregation Methods (PAM) for solving linear systems of equali- ties and/or inequalities, generate a new iterate xk+1 by projecting the current point xk onto a separating hyperplane generated by a given lin...

"Electroencephalography (EEG) system validation faces a fundamental challenge: the absence of ground truth when measuring human subjects. Physical head phantoms provide controlled testing environments with known signals;...

This paper presents an application of the ant colony metaphor for continuous space optimization problems. The ant algortihm proposed works following the principle of the ant colony approach, i.e., a population of agents ...
