computational complexity

基本解释

And that is a preface to an idea of computational complexity we're going to come back to.
这是我们日后,要讲的计算复杂度的,一个前言。
Big-O notation: Computational complexity theory uses big-O notation to describe how input-data size affects an algorithm's use of computational resources.
Big-O notation：计算复杂性理论使用大 0 符号描述输入数据大小如何影响计算资源对算法的使用。
Calculations of computational complexity seem to be one of the harder subjects for students; there's no doubt of their value, though, when they lead to such speedups.
对于学生来说，计算“计算复杂度”似乎是较难的课题之一；但是当这些方法产生这样的加速时，它们的价值无庸置疑。

And that is a preface to an idea of computational complexity we're going to come back to.

That's an important observation, and as we get to the part of the course we talk about computational complexity, you'll see that what we really care about is not how efficient the program is on easy problems but how efficient it is on hard problems.
我们已经学习了这门课程的一部分了，我们要开始认识到,计算的复杂度这个概念，你会学习到我们在乎的并不是,算法在简单问题上的工作效率,而是解决复杂问题的效率。
