Conversely, if you think the goalie's going to shoot to the right with probability more than a ?, then the best you can do is represented by the pink line, and that's shooting to the left, or if you think the goalie's going to dive to the right with the probability more than a ?, the best you can do, your best response is to shoot to the left.
相反如果你认为门将扑向右侧的概率,大于?的情况下,此时你最佳策略用粉线表示,即从左路射门,也就是说如果你觉得门将扑向右路的,概率大于?的话,你最好选择从左路射门

你们有谁有印象它们有什么用吗?,我当时是不知道,所以如果你们不记得,这部分也没有关系。
You can go ahead and use that equation, or you could figure it out every time, because if you know the total number of nodes, and you know the angular node number, then you know how many nodes you're going to have left.
你们可以直接用这个方程,或者每次都自己算出来,因为如果你们知道了总的节点数,又知道角向节点数,就知道剩下的节点数是多少。
One way to think about it, if we want to use a classical analogy, which often helps to give us an idea of what's going on, is the spin of an electron, we can picture it rotating on its own axis.
如果我们用一个,经典的比喻来考虑它的话,这经常会帮助我们建立起一些概念,就是我们可以把电子的,自旋想象是它绕着轴自转。

And when we talk about intensity in terms of units, we usually talk about watts, so if you change your lightbulb, usually you see the intensity in terms of watts.
当我们讨论强度的单位时,我们经常用瓦特,所以如果你更换灯泡,你通常会看到,以瓦特为单位的强度值。
Not so easy to see. All right, but this is actually a great one of those educational moments. This is a great example to think recursively. If I wanted to think about this problem recursively- what do I mean by thinking recursively?
看不太出来,好,但实际上是一个有教育意义的时刻,这是一个很好的关于递归的例子,如果我用递归的思想,去考虑这个问题-,我该怎么用递归去解决这个问题呢?
If I look for, say, minus 1, you might go, gee, wait a minute, if I was just doing linear search, I would've known right away that minus one wasn't in this list, because it's sorted and it's smaller than the first elements.
如果我要查找-1,你可能要怒了,呵呵,等一等,如果我用的是线性查找,我不会知道-1不在这个列表中,但是列表是排好序的,1又比第一个元素小。
I've added the ability to have more complex data structures here. But I dropped a hint in the first lecture about what you could computer with things. In fact if you think for a second about that list, you could ask what can I compute with just that set of constructs?
我添加了使用更复杂的数据结构的能力,但是我在第一节课给大家了了一个,关于你可以用什么来做计算的暗示,实际上如果你思考,这个列表一会儿的话,你会问我可以用?
You can take a problem that might be relatively intuitive to solve but when you scale this thing up as is increasingly the case in the web, in large data systems, and so forth, you actually have to now think smart, you actually have to think efficiently and you have to solve this problem effectively.
你可以把一个问题用比较直观的方法解决,但如果你把此类问题的数量增大,正如越来越多的互联网,和大规模数据系统中出现的问题等等,你应该考虑怎样才能更简便,怎样才能更高效,你应该用行之有效的方法处理问题。
Then also you'll be asked to do identifying information if you print it out from the program itself, but if you go up to your web browser print option and print from that particular thing then you can do it and no identifying information will be necessary.
如果你想直接从网上打印分析结果,就得提供个人信息,但是,如果你用浏览器中的打印选项,只打印营养分析结果,你就可以打印文件而无需提交个人信息
A TSV file, tab-separated values uses the same thing but a tab character, if you wanna output an actual tab character, the result of hitting the tab key, \t you do use backslash T. That's so those kinds of files are made.
而TSV文件,“制表符分隔“文件,顾名思义,就是用制表符来分隔每一列,如果你想输出一个真正的制表符,点击tab键,你也可以用,这就是那些文件的形成方式。
