  您好，我跑了个100*100的嵌套扫描，但是跑完后没有彻底结束，也没有卡住，仿真时间挺长的，请问是什么情况？有什么解决办法吗

  100*100的嵌套扫描，那是1万个仿真文件，你的内存够吗？
  一般应该先粗扫描，或者分段扫描，不要指望一个扫描扫描就能得出最佳的结果。
  你的情况反而不如直接优化。

  您好，我的内存是够的，粗略扫描已经可以得到不错的结果，我才进行进行精确扫描的。您说的我的情况不如直接优化是什么意思呢？谢谢您的回答

  1万个文件，每个文件1G，那就要10^4GB 的内存，你确认内存足够？
  你如果做优化，50粒子数200代才需要1万个文件，很可能不到100代优化就找到了，每次也就是记录50个文件，你试一下。

  非常感谢您的回复！您说的做优化我没有理解，可能是我学习的欠缺，能麻烦您具体说一下您上一条说的优化的细节和步骤吗？谢谢！
