This paper presents a comparison of experimental results between Particle Swarm Optimization (PSO) and Genetic Algorithms (GAs) for the numerical optimization problems. The idea was to implement a PSO algorithm, to see its real behavior by comparing it with the performance that presents GAs in the optimization of classical benchmarking nonlinear functions. Moreover, the effects of different parameters values of the PSO and GAs algorithms are presented. Computational results showed that the optimization by particle swarm has a better behavior than genetic algorithms in most of the used benchmarks.
