我在康威的生活游戏中遇到了麻烦（如果你不熟悉它，这里是一个解释它并指向顶端的链接是规则http://en.wikipedia.org/wiki/Conway's_Game_of_Life）。我正在使用gridworld，当我运行代码时，它会生成网格并更改其状态。这一切看起来好像是正常工作。然而，应该死亡/活着的细胞不会。相反，看似随机的细胞分类会改变它们的状态。我无法弄清楚这个问题。我已经检查过，以确保找到了正确的邻居数量，if语句正常工作，并且如果我正在比较正确的事情。所有这些似乎都奏效，但我看到了意想不到的结果。请帮我解决这个问题。提前致谢。 PS。请忽略注释掉的代码。他们是测试/失败的尝试，使其工作。 这里是我的代码：conways生活中的游戏无法正常工作
