Abstract In this work is described a methodology for developing optimized pattern recognition systems by means of genetic machine learning. The idea is to redefine the set of classes that must be learned by the classification system, mapping them into another set which the Voronoi vectors can successfully classify a sample into one of the original classes. The main objective of this approach is to find the minimum number of classification rules (by minimizing the number of classes in the new set) that maximizes the number of correct classifications. To accomplish that, a genetic algorithm was design. In
