People tend not to realize that the first question you should always ask yourself, is this really just something that's well-known in disguise?

已解决问题呢？,这是一个最短路径问题吗？,这是一个最近邻居问题吗？

End up where you started. It's not quite the same as the shortest path, and figure out the way to do that that involves spending the least money. Or the least time, or something else.

最后回到最初的地方,这和最短路径问题有些不同,需要找出一条花费最少,或者费时最少或者满足其它条件的路径。

And tomorrow it's recitation, we'll spend quite a bit of time on shortest path problems.

也就是说我们会在最短路径问题上,花上很多时间。
