Python实现粒子群算法PSO

去github上吧scikit-opt这个库下载下来，
https://github.com/guofei9987/scikit-opt
如果不想下载整个库，也可以只下载pso.py这个文件

PSO

def demo_func2(p):    # Sphere函数    out_put = 0    for i in p:        out_put += i ** 2    return out_put

from pso import PSOmy_pso = PSO(func=demo_func2, pop=30, dim=5, max_iter=100)fitness = my_pso.fit()print(my_pso.gbest_x)print(my_pso.gbest_y)my_pso.plot_history()
