简单的粒子群优化程序，模拟鸟群飞行时合作，将每只小鸟比作一个粒子。粒子通过自己的历史最优值和所有粒子的最优值来调整自己的速度和位置，从而达到目的地。-Simple particle swarm optimization procedure, the simulation when flying birds, compared each bird to a particle. Particle optimal value through its own history and the optimal value of all particles to adjust their speed and position, thus reach the destination.
