本课程教授高效率算法的设计及分析技巧，并着重在有实用价值的方法上。

This course teaches techniques for the design and analysis of efficient algorithms, emphasizing methods useful in practice.

当然还有效率更高的素数测试方法，不过这种算法最容易理解。

Of course, much more efficient algorithms for testing primality exist, but this one is the easiest to understand.

或许，某天我们有能力找到一种兼顾时间效率和空间效率的算法，那无疑将是贯穿时空的桥梁。

Maybe someday we'll be able to find algorithms that are extremely efficient in both speed and memory, Bridges in the Space-Time continuum.

And then we're going to turn to the question of efficiency. How do we measure efficiency of algorithms? Which is going to be a really important thing that we want to deal with, and we'll start it today, it's undoubtedly going to take us a couple more lectures to finish it off.

然后我们会回头继续讨论效率问题,我们如何计算算法的效率？,我们处理这些问题的时候,最重要的事情是什么？,我们今天要去讨论这个问题，毫无疑问我们要用,挺多节课来学习这个。

So what we want to do, is, I guess another way of saying it is, efficiency is really about choice of algorithm.

因此我们想做的就是，换种说法，效率实际上是算法的选择，我们想要培养你们。

Alright, I have the problem so clearly this algorithm whatever it's gonna be is gonna be at least twice as fast because I'm doing half as much work.

现在，这个问题已变得清晰,不管怎么样，排序算法的效率,至少是之前的两倍,因为我只需要做一半的工作。
