对典型的粒子群算法的改进，是一类权重改进的粒子群算法，利用新型递减权重法来更新粒子速度和位置，用来解决静态单目标优化问题-It is the improved particle swarm optimization algorithm. It introduced a kind method named new decreasing weight to update the position and velocity of the particle. It can be used for handle single objective problems in static environment.
