Experimental comparisons of the running time of approximate string matching algorithms for the k differences problem are presented. Given a pattern string, a text string, and an integer k, the task is to find all approximate occurrences of the pattern in the text with at most k differences (insertio
We present a new string matching algorithm optimal on average (with equiprobability and independence of letters, in O m + n log m/m , where n is the size of the text and m the size of the searched word, both taken on an alphabet ) and linear in the worst case (in O m + n ). Of all the algorithms tha
