摘要:	摘要： Particle swarm optimization (PSO) has been successfully applied to solve many practical engineering problems. However, more efficient strategies are needed to coordinate global and local searches in the solution space when the studied problem is extremely nonlinear and highly dimensional. This work proposes a novel adaptive elite-based PSO approach. The adaptive elite strategies involve the following two tasks: (1) appending the mean search to the original approach and (2) pruning/cloning particles. The mean search, leading to stable convergence, helps the iterative process coordinate between the global and local searches. The mean of the particles and standard deviation of the distances between pairs of particles are utilized to prune distant particles. The best particle is cloned and it replaces the pruned distant particles in the elite strategy. To evaluate the performance and generality of the proposed method, four benchmark functions were tested by traditional PSO, chaotic PSO, differential evolution, and genetic algorithm. Finally, a realistic loss minimization problem in an electric power system is studied to show the robustness of the proposed method. 出版者： New York: Hindawi Publishing Corporation 出版日期： 2014-01-01 出處： Mathematical problems in engineering, 2014-01, Vol.2014 (1) 資源來源：華藝CEPS中文電子期刊服務版權： Copyright © 2014 Ying-Yi Hong et al. 版權： Copyright © 2014 Ying-Yi Hong et al.
