BK树或者称为Burkhard-Keller树,是一种基于树的数据结构,被设计于快速查找近似字符串匹配,比方说拼写纠错,或模糊查找,当搜索”aeek”时能返回”seek”和”peek”. 本文首先剖析了基本原理,并在后面给出了Java源码实现. BK树在1973年由Burkhard和Keller第一次提出,论文在这<Some approaches to best match file searching>.这是网上唯一的ACM存档,需要订阅.更细节的内容,可以阅读这篇论文<Fast Ap…

Trie,又经常叫前缀树,字典树等等.它有很多变种,如后缀树,Radix Tree/Trie,PATRICIA tree,以及bitwise版本的crit-bit tree.当然很多名字的意义其实有交叉. 定义 在计算机科学中,trie,又称前缀树或字典树,是一种有序树,用于保存关联数组,其中的键通常是字符串.与二叉查找树不同,键不是直接保存在节点中,而是由节点在树中的位置决定.一个节点的所有子孙都有相同的前缀,也就是这个节点对应的字符串,而根节点对应空字符串.一般情况下,不是所有的节点都有对应…
