您好，莫烦老师，非常感谢你的视频分享。 我对ES neuroevolution的算法有个疑问想请教下，你的算法中只用了20个individuals就可以起到比较好的效果了，我看openai的算法，为什么他们需要1000个才行？而且我将openai算法中的individuals的数量减少了，似乎他们的算法就无法收敛了。

莫烦哥你好，我想问一下这个地方为什么又执行 p.run(eval_genomes, 10) 这个函数，前面不都是已经训练好了吗，最后为什么又训练了10次 ``` p = neat.Checkpointer.restore_checkpoint('neat-checkpoint-49') p.run(eval_genomes, 10) ``` # https://github.com/MorvanZhou/Evolutionary-Algorithm/blob/master/tutorial-contents/Using%20Neural%20Nets/NEAT/run_xor.py 第59行
