Abstract(in Japanese) (See Japanese page)
Abstract(in English) Particle Swarm Optimization (PSO) is a metaheuristics using the swarm intelligence. Although PSO is usually applied to the function optimization problem, the search capability is influenced by such properties of objective function as unimodal, multimodal and non-separable behaviors. Especially, it is difficult to search a solution for a non-separable objective function. Koguma and Aiyoshi reported that the difficulty was caused by an anisotropy of velocities of PSO particles and proposed Linked Random Model to reduce the anisotropy. They also reported that, instead of reducing the anisotropy, the global search capability decreased by the model. In this study, we propose the random search PSO (RS-PSO) with Linked Random updata by applying linked random model to RS-PSO that is a variant of PSO improved in the global search ability. We perform the numerical simulations of minimization problems of various types of benchmark functions by our proposed model and find that our proposed model shows high search capability for unimodal, multimodal and non-separable functions.
