求解TSP的改进自组织PSO算法
Improved self-organizing particle swarm optimization for Traveling Salesman Problem
摘要
Abstract
To alleviate the premature convergence of basic particle swarm optimization (PSO), an improved self-organized particle swarm optimization(SOPSO) algorithm is proposed, whose parameter setting are improved based on the characteristics of self-organizing criticality in the interest of the diversity of population.That is, the self-organizing inertia weight and acceleration coefficients are applied and the mutation operator is introduced.In view of the concept of "Swap operator" and "Swap sequence",the improved SOPSO algorithm which can search in the discrete domain directly is designed to solve the traveling salesman problem (TSP).Then compare the results of the improved algorithm with those of the basic PSO and other improved PSO algorithm.The results show that the improved SOPSO algorithm is effective.关键词
