编辑距离(Minimum Edit Distance,MED),也叫 Levenshtein Distance。他的含义是计算字符串a转换为字符串b的最少单字符编辑次数。编辑操作有:插入、删除、替换(都是对a进行的变换)。用lev(i, j) 表示 a的前i个单词和 b的前j个单词的最短编辑距离(即从后往前)。可以分为以下几种情况: i == 0 或j == 0...
1)定义 编辑距离(Minimum Edit Distance,MED),又称Levenshtein距离,是指两个字符串之间,由一个转成另一个所需要的最少编辑操作次数。允许的编辑操作包括:将一个字符替换成另一个字符(substitution,s),插入一个字符(insert,i)或者删除一个字符(delete,d),如下图所示: 在大学算法设计相关课程上,想必大家都已经学...
