前言
修订一本书向来都是一项艰巨的任务。我们既希望保留第
1
版（ 于
2009
年出版）中的精华，
也希望弥补其中的一些不足并增加一些新的篇幅。在第
2
版中，我们延续了第
1
版中列
出的原则，包括：
•
使用实际代码而非伪代码来描述算法。
•
将算法独立于解决的问题之外。
•
恰到好处地介绍数学知识。
•
以经验主导支撑数学分析。
在更新修订过程中，我们精简了文字描述，简化了一些布局，从而有助于补充新的算法
和其他内容。我们相信，从
概括
的角度介绍计算机科学的一个重要领域，会对实用软件
系统有着深远影响。
第 2 版的变动
在修订过程中，我们遵循以下原则：
挑选新的算法
在第
1
版出版之后，我们常常会收到一些留言，比如，“为什么漏掉了
归并排序
？”
或“为什么没有介绍
快速傅里叶变换
（
Fast Fourier Transform
，
FFT
）？”虽然我们
无法满足所有这些要求，但第
2
版还是增添了一些新的算法，包括：
•
Fortune
算法
，它用于计算点集的
Voronoi
图。
•
归并排序，既包括针对内存数据的内部排序，也包括外部文件的外部排序。
•
多线程
快速排序
。
