关于本书：《算法设计与分析》
作者： hwdong
《算法设计与分析》是一本以问题为驱动、以策略为主线的算法入门书籍。本书从算法基础概念入手，系统讲解穷举、贪心、分治、动态规划、回溯等经典算法设计策略，并通过大量精选实例，帮助读者深入理解每种策略的核心思想与适用场景。
内容简介
- 算法基础：厘清算法与程序的关系，介绍算法分析的核心工具（渐近记号、递归方程求解）。
- 线性穷举：通过“两数之和”“N皇后”等问题，展示系统搜索解空间的方法。
- 贪心法：讲解“每步取最优”的贪心思想，涵盖活动安排、哈夫曼编码、最小生成树等经典问题。
- 分治法：剖析“分而治之”的范式，包括归并排序、快速排序、Karatsuba乘法等。
- 动态规划：深入探讨最优子结构与重叠子问题，通过背包问题、最长公共子序列等案例掌握递推关系构建。
- 状态空间搜索：介绍回溯与分支限界，解决N皇后、旅行商问题等组合优化难题。
本书特色
- 深入浅出：用通俗语言直击算法本质，避免抽象数学推导。
- 例子驱动：每个知识点配有经典例题，边学边练。
- 双语言实现：同时提供C++和Java完整代码，兼顾不同编程背景。
- 干货满满：内容精炼，每一页都有价值。
目标读者
- 计算机专业本科生、研究生
- 算法自学者、编程爱好者
- 备战技术面试的开发者
- 希望系统梳理算法知识体系的科研人员

Earn $8 on a $10 Purchase, and $16 on a $20 Purchase
We pay 80% royalties on purchases of $7.99 or more, and 80% royalties minus a 50 cent flat fee on purchases between $0.99 and $7.98. You earn $8 on a $10 sale, and $16 on a $20 sale. So, if we sell 5000 non-refunded copies of your book for $20, you'll earn $80,000.
(Yes, some authors have already earned much more than that on Leanpub.)
In fact, authors have earned over $15 million writing, publishing and selling on Leanpub.
