Abstract
Many foragers and wandering animals have been shown to follow a Levy distribution of steps and it is conjectured here that this distribution may be useful for optimization algorithms too. This paper investigates the effectiveness of replacing the particle dynamics within particle swarm optimization (PSO) by random sampling from a Levy distribution. The resulting Levy PSO is demonstrated to perform as well, or better, than a standard PSO or equivalent Gaussian models over a range of benchmark problems.
