Book Abstract

2.5.5 最小生成树
给定一个无向图，如果它的某个子图中任意两个顶点都互相连通并且是一棵树，那么这棵树就叫做生成树（Spanning Tree）。如果边上有权值，那么使得边权和最小的生成树叫做最小生成树（MST，Minimum Spanning Tree）。
例如我们假设有这样一个图：把顶点看作村庄，边看作计划要修建的道路。为了在所有的村庄间通行，恰好修建村庄数目—1条道路时的情形就对应了一棵生成树。修建道路需要投入建设费，那么求解使得道路建设费用最小的生成树就是最小生成树问题。
常见的求解最小生成树的算法有Kruskal算法和Prim算法。很显然，生成树是否存在和图是否连通是等价的，因此我们假定图是连通的。
1.最小生成树问题1（PrIm算法）
首先我们介绍Prim算法。Prim算法和Dijkstra算法十分相似，都是从某个顶点出发，不断添加边的算法。
首先，我们假设有一棵只包含一个顶点v的树T。然后贪心地选取T和其他顶点之间相连的最小权值的边，并把它加到T中。不断进行这个操作，就可以得到一棵生成树了。接下来我们来证明通过这个方法得到的生成树就是最小生成树。

Introduction

如今，形形色色的程序设计竞赛层出不穷，听说过Google Code Jam、TopCoder、ACM-ICPC的读者恐怕不在少数。本书要介绍的正是这类以在规定时间内、又快又准地解决尽可能多的题目为目标的程序设计竞赛。
程序设计竞赛内涵丰富，即便是经验老道的程序员，要想在比赛中取得好成绩也绝非易事。要在程序设计竞赛中取胜，不仅需要运用灵活的想象和丰富的知识得出正确的算法，还需要一气呵成地实现并调试通过。
另一方面，程序设计竞赛对新手而言亦非遥不可及。为了让更多的参赛选手体会到比赛的乐趣，大多数比赛都会准备若干面向初学者的题目。另外，即便未能在比赛中取得好成绩，通过比赛，也能够使自己的能力得到有效的锻炼。最重要的是，大家能够享受到激烈的比赛带来的乐趣。
本书的作者们参加过众多程序设计竞赛，在平时的练习和学习中，也获得了各种各样的知识与技巧，本书将这些知识技巧总结成册，主要介绍算法及其在相关问题中的应用。本书依照由易及难的顺序对问题进行讲解，章节的编排也参考了主题的难易程度及其相互的联系，内容较多的主题则按难易程度划分为多个子主题分别介绍。各个主题由算法介绍和例题讲解穿插而成。
只要是具有编程基础知识的读者，均适合阅读本书。书中的源代码均用C++实现，不过只用到了其基本功能，所以即便读者不熟悉C++也不影响阅读。
【关于再版】
令人惊喜的是，本书的第1版受到了广大读者的高度评价，在此表示感谢。特别是一些并不热衷于程序设计竞赛的读者也购买了本书。这是因为通过本书不仅可以学到算法，更能学到其设计和运用的思想。这正是本书划时代的亮点。
本书第2版追加了计算几何、搜索减枝、分治法和字符串相关算法4个主题。此外还追加了方便读者加深理解的练习题，并为学有余力的读者列出了书中未涉及的拓展主题，进一步丰富了本书内容。
