我检查了一下，我用两个seed跑一轮的时候，事实上运行了很多轮，不是很清楚是什么原因。。。初学遗传算法感觉都要蒙圈了，求大神指教。

哦哦，我是说呢，用四个seed运行两轮，fitness函数调用了55次。不过我没看出来怎么改，还是得辛苦大神。。。

我刚发现有人问过和我类似的问题，就是30个seed迭代一轮，实际调用fitness函数调用了900多轮，导致内存消耗很大。

你好，这个可能是我在计算种群个体适应度的时候动态的传入适应度函数导致重复的运算，我近期会尝试修复这个bug，感谢提出

还有一点，就是调用mpirun的时候fitness函数的调用会更加倍增。

你好，我在刚刚的commit中修复了多余调用适应度函数的问题，你可以进行测试，有问题欢迎提出哈。另外mpirun是同时启动多个mpi进程执行，在迭代开始产生新种群的时候会按照进程数进行分割，所以调用增加是正常的，你可以看看效率有没有提升
