WebNov 30, 2024 · Knuth-Morris-Pratt Algorithm. Now we will discuss the last algorithm for today. This one is very complicated but I will try to make it as simple as possible. The idea behind this algorithm is that the naïve approach is great unless the string and the pattern have many repeats – like for example searching for AAAB in AAAXAAA.
In computer science, the Knuth–Morris–Pratt string-searching algorithm (or KMP algorithm) searches for occurrences of a "word" W within a main "text string" S by employing the observation that when a mismatch occurs, the word itself embodies sufficient information to determine where the next … See more A string-matching algorithm wants to find the starting index m in string S[] that matches the search word W[]. The most straightforward algorithm, known as the "Brute-force" or "Naive" algorithm, is to look for a word … See more Since the two portions of the algorithm have, respectively, complexities of O(k) and O(n), the complexity of the overall algorithm is O(n + k). These complexities are the same, no matter how many repetitive patterns are in W or S.
