Particle swarm optimization algorithm and its parameter set
Speciality: Information and Computing Science

Abstract
　　　Particle swarm optimization is an emerging global based on swarm intelligence heuristic search algorithm, particle swarm optimization algorithm competition and collaboration between particles to achieve in complex search space to find the global optimum. It has easy to understand, easy to achieve, the characteristics of strong global search ability, and has never wide field of science and engineering concern, has become the fastest growing one of the intelligent optimization algorithms. This paper introduces the particle swarm optimization basic principles, and analyzes its features. Paper around the particle swarm optimization principles, characteristics, parameters settings and applications to conduct a thorough review, focusing on a single factor analysis of variance, analysis of the particle swarm optimization algorithm in the inertia weight, acceleration factor setting the basic properties of the algorithm the impact of the experience of the algorithm given parameter setting. Finally, its future researched and prospects are proposed.
