dc.description.abstract | In this work we present a proposal to improve Genetic Algorithm method by coupling
it to the techniques of discretization of the configurational space via the multi-grid
methodology, and by employing a topological selection of the offsprings via graph theory.
The best performance for clusters of 13 and 19 aluminum atoms shows that the multi-grid
tecniques can increase the efficiency of the genetic algorithm, mainly when a more extensive
search is performed in an initially sparse grid of points. We also show that a greater
improvement in the efficiency of the genetic algorithm can be obtained when we select
the offsprings of the sucessive generations in order to be topologically distinct from each
other. | |
