分析算法的人享有双重的幸福。首先，他们能够体验到优雅数学模式纯粹的美，这处模式存在于优美的计算过程之中。其次，当他们的理论使得其他工作能够做得更快、更经济时，他们得到的是实际的褒奖。因此，我们盼望已久的这部著作极受欢迎。该书作者不仅是该领域世界范围内的领袖，而且还是阐述的大师。

　　本书全面介绍了算法的数学分析所需要使用的主要技术，包括经典的数学内容（如离散数学、初等实分析、组合学等）以及经典的计算机科学内容（如算法和数据结构等）。书中重点强调了平均情形下的算法分析，同时也包含对最坏情形下的算法分析。
尽管人们极为关注算法的数学分析，但是广泛使用的方法和模型方面的基本信息尚不能为该领域的工作和研究所直接使用。作者在本书中处理这种需求，把该领域出现的挑战以及为跟上新的研究以迎接这些挑战所必需的背景资料完美地结合在一起。
