PSO
PSO算法简单、易实现、计算量小,而且PSO 对初始点依赖性不大,具有更强的全局优化能力,也能较快的的收敛于可接受解。这是改进的pso,请多多指教。(PSO algorithm is simple, easy to realize the advantages of a small amount of computation and computational efficiency, and PSO dependence of the initial point, with stronger global optimization capability, but also faster convergence to an acceptable solution. This improved pso, exhibitions)
