粒子群比遗传算法规则更为简单，它没有遗传算法的“交叉”(Crossover) 和“变异”(Mutation) 操作，它通过追随当前搜索到的最优值来寻找全局最优。这种算法以其实现容易、精度高、收敛快等优点引起了学术界的重视，并且在解决实际问题中展示了其优越性。粒子群算法是一种并行算法。(It is more simple than the genetic algorithm rule. It doesn't have the crossover (Crossover) and the Mutation operation of genetic algorithm. It searches the global optimum by following the best value currently searched. This algorithm has attracted the attention of academic circles for its advantages of easy realization, high precision and fast convergence, and shows its superiority in solving practical problems. Particle swarm optimization (PSO) is a parallel algorithm.)
