Abstract
In this paper, we aim to analyze the performance of some variants of the harmony
search (HS) metaheuristic when solving systems of nonlinear equations through the
global optimization of an appropriate merit function. The HS metaheuristic draws its
inspiration from an artistic process, the improvisation process of musicians seeking a
wonderful harmony. A new differential best HS algorithm, based on an improvisation
operator that mimics the best harmony and uses a differential variation, is proposed.
Computational experiments involving a well-known set of small-dimensional problems
are presented.Fundação para a Ciência e a Tecnologia (FCT
