| Abstract | Genetic algorithms, inspired by the theory of evolution of species, are intended to be unfair. Individuals compete against each other and the best-adapted ones prevail. Unfairness is due to big dierences of skills, generally evaluated by a fitness measure, in a population of individuals competing for survival. However, population diversity is important to preserve some features that are not always associated to high ranked skills. Such diversity can be achieved by imposing fairness rules to the competition. The adaptive hierarchical fair competition genetic algorithm has been proposed to comply with this feature by segregating individuals in casts or demes, according to their fitness. This work proposes a parallel implementation that enhances the capabilities and computational performance of an adaptive hierarchical fair competition genetic algorithm. The code was parallelized using the MPI (Message Passing Interface) communication library and executed in a distributed memory parallel machine, a PC cluster. Test results are shown for standard numerical optimization problems presenting hundreds of variables. |
