中文简介: | ";好的,今天我们将开始讨论一类称为贪婪算法的特殊算法。但我们将在图的上下文中进行。所以,我想复习一些图表,这些图表大部分可以在附录B的课本中找到。所以,如果你最近没有在附录B中复习过,请坐下来复习附录B。它将得到回报,特别是在我们的带回家的测验中。所以,提醒一下,有向图,什么是有向图?这是什么意思?有向图,好吗?有向图,g等于(v,e),好的,有一组顶点。 |
课程简介: | "OK, today we're going to start talking about a particular class of algorithms called greedy algorithms. But we're going to do it in the context of graphs. So, I want to review a little bit about graphs, which mostly you can find in the textbook in appendix B. And so, if you haven't reviewed in appendix B recently, please sit down and review appendix B. It will pay off especially during our take-home quiz. So, just reminder, a digraph, what's a digraph? What's that short for? Directed graph, OK? Directed graph, G equals (V,E), OK, has a set, V, of vertices... |
