但什么是最优的政体？

But what is the best regime?

工具只能确保代码正确，但不一定是最优的。

It can ensure correct code, but not the best code.

当然，有一些情况下，您只是不得不让您的程序尽可能最优，但是我只有在确定其必要性之后才这样做。

Sure, there are some cases where you simply have to make the program as optimal as possible, but I do that only after confirming the necessity.

The notion here is that you can get a globally optimal solution from locally optimal solutions to sub-problems.

这里的概念是你可以通过,子问题的局部最优方案,得到全局优化解决方案。

She said, no matter what the other person does, she reckons she'd get a better grade if she chose Alpha.

她说无论别人怎么选,她觉得选α会使自己得到最优的结果

And then I take as many raisins as will fit in and I leave. Right? I hope almost every one of you could figure out that was the right strategy.

然后我再尽量装葡萄干,最后我离开，对吧？,我希望你们每个人都发现了这是最优策略。
