我的模型曾经能够在大约10个小时内完成，但现在需要数周时间。有人可以看看我的代码并提出建议。
我是网络标识和现实主义的新手，虽然模型正在做我想做的事情。它可能没有很高效的编码。非常感谢任何可以给出的建议。
奇怪的是，每天的长度是86400蜱。第1天和第2天需要2:30分钟才能运行一天，在第3天这会跳到14分钟，随着时间的推移它会越来越慢。我不知道为什么

答案 0 :(得分：3)
您的问题是be-active程序。首先，你要求所有成年人（狼）执行be-active程序，但程序也要求所有成年人做某事。你可能在其他地方也犯了同样的错误。
此外，您应该查找mod运算符，这会大大缩短您的if management代码。它还可以加快运行速度，因为代码只需要检查一天是7的倍数，而不是现在检查的次数。
