http://staff.ustc.edu.cn/~csli/graduate/algorithms/book6/chap34.htm One possible definition of the approximate string matching problem is the following: Given a pattern string and a text string , find a substring in T, which, of all substrings of T, has the smallest edit distance to the pattern P. A brute-force approach would be to compute the edit distance to P for all substrings of T, and then choose the substring with the minimum distance. However, this algorithm would have the r…
