Abstract:In this study, we propose a novel optimization method, which can track multiple optimal solutions for dynamic problems. In our previous study, we proposed a gravitational particle swarm algorithm (GPSA), which is able to search for multiple optimal solutions. In this paper, first, we apply the original GPSA to a multi-solution tracking problem and reveal its drawback. Second, we propose a modified GPSA, called 𝜏GPSA, by replacing original GPSA's update rule for personal bests with a tolerance update rule. Fin… Show more
