| 內容簡介： |
《算法设计与分析》共8章，主要从算法的分析与设计两个方面进行介绍。首先，系统地介绍了算法分析的基本方法，包括非递归算法和递归算法，并详细介绍了Master定理。然后，系统地介绍了各种算法设计策略，包括分治策略、动态规划算法、贪心算法、回溯法、分支限界法、线性规划与网络流等。对于每种算法设计策略，从该策略的基本思想、适用问题、算法步骤或框架、应用范例等多个方面详细讲解，对于复杂的算法设计策略还给出了相关例题。书中包含大量的范例和对应的实现代码，让读者对算法设计策略的基本思想和核心设计步骤有深入的理解与掌握，能够让读者掌握各种算法设计策略的精髓，能够提高读者的算法设计能力，能够让读者具备分析具体问题、选择算法设计策略、给出算法代码的能力。
《算法设计与分析》主要作为普通高校教材，适用于计算机科学与技术相关专业的本科和研究生阶段的教材，也可以作为从事实际问题求解的研究工作者的入门教材。
