Abstract

This article presents an analysis of the sensitiveness of evolutionary algorithms to the change of the random number generator when using a real-world problem --the fitting of a theoretical curve to an experimental data set-- as test. On the one hand, the evolutionary algorithms selected: particle swarm algorithm, differential evolution and genetic algorithm are widely used in optimization problems. And, on the other hand, the random number generator used: Mersenne Twister and GCC rand(), are the most frequently linked to evolutionary algorithms, as well as they are considered as high-quality. As a consequence of this work, an assessment is stated about the sensitiveness of the evolutionary algorithms studied to the choice of the random number generator.
