So what we see is, again perfectly reasonable statistical techniques, but not looking at things in the right way.

所以我们这里可以看到，还是很完美很有逻辑的统计学工具，但是他们没有用正确的方式去看待数据。

And then we're going to try a demo to see if we can convince ourselves that the kind of calculations we make work out perfectly, and we'll do a test up here about half way through class.

然后我们将会尝试演示去看看,是否可以确信我们能够很好的,做出这个类型的计算，我们将在课程中做一个测试。

The thing is still not dominated and we could still have done exactly the same analysis, and actually you can see I'm not very far off in the numbers I made up, but things are not perfectly symmetric.

这虽然不能成为劣势策略,但我们还是能得出一样的分析结果,实际上这和我编的数字相差也不是很远,凡事并不总是绝对对称的嘛

They are computationally challenged, meaning, at the time they were invented, they were perfectly good sorting algorithms, there are better ones, we're going to see a much better one next time around, but this is a good way to just start thinking about how to do the algorithm, or how to do the sort.

他们是相当棒的排序算法，是有更好的算法，我们下一次,就会看一个更好的，但是开始想想,如何完成算法，或者说是如何排序,是一个好的学习方法,恩，再试试吧,如何来排序呢？
