Strings `A` and `B` are `K`-similar (for some non-negative integer `K`) if we can swap the positions of two letters in `A` exactly `K` times so ...
Two strings X and Y are similar if we can swap two letters in different positions of X , so thatit equals Y . For example, tars and rats are similar swapping at positions and , and rats and arts are ...

这篇我们看看最长公共子序列的另一个版本,求字符串相似度(编辑距离),我也说过了,这是一个非常实用的算法,在DNA对比,网 页聚类等方面都有用武之地。 一:概念 对于两个字符串A和B,通过基本的增删改将字符串A改成B,或者将B改成A,在改变的过程中我们使用的最少步骤称之为“编辑距离 ...
余弦相似度 计算公式为: P(A,B) = sqrt(A × B) / (|A| × |B|) 设有两个字符串: ABCDEFG ABCHIJK 其中共有11个字符,为: A B C D E F G H I J K 如果,不考虑他们之间的关联性以及顺序等隐私 ...
