内容简介

《算法分析导论（第2版）（英文版）》全面介绍了算法的数学分析中所涉及的主要技术。涵盖的内容来自经典的数学课题（包括离散数学、初等实分析、组合数学），以及经典的计算机科学课题（包括算法和数据结构）。《算法分析导论（第2版）（英文版）》的重点是“平均情况”或“概率性”分析，书中也论述了“最差情况”或“复杂性”分析所需的基本数学工具。

《算法分析导论（第2版）（英文版）》第 1 版为行业内的经典著作，本版不仅对书中图片和代码进行了更新，还补充了新章节。全书共 9 章，第 1 章是导论；第 2~5 章介绍数学方法；第 6~9 章介绍组合结构及其在算法分析中的应用。除每章包含的大量习题以及参考文献外，《算法分析导论（第2版）（英文版）》特设配套免费学习网站，为读者提供了很多关于算法分析的补充材料，包括课件和相关网站的链接，帮助读者提高学习兴趣，完成更深入的学习。

《算法分析导论（第2版）（英文版）》适合作为高等院校数学、计算机科学以及相关专业的本科生和研究生的教材，也可供相关技术人员和爱好者学习参考。

作者简介

Robert Sedgewick于1985年开始在普林斯顿大学任教，是该校计算机系的发起人，现任该校的计算机科学William O. Baker教授。他曾任Adobe Systems公司总监，并在Xerox PARC、IDA和INRIA等公司从事研究。他是算法领域入门著作Algorithms，Fourth Edition（《算法》第4版）的作者。Sedgewick教授在斯坦福大学师从Donald E. Knuth院士，获得博士学位。

Philippe Flajolet曾任法国罗克库尔INRIA资深研究总监，创建并领导了ALGO研究组。他因在算法分析领域的开创性研究而声名鹊起，在分析组合学方面梳理并发展出了强大的新方法，解决了很多长期悬而未决的难题，并在世界各地从事算法分析的教学。Flajolet博士是法国科学院成员。
