WebMar 7, 2011 · Brute-force string matching compares a given pattern with all substrings of a given text. Those comparisons between substring and pattern proceed character by character unless a mismatch is found. … WebJul 1, 2000 · The so-called naive or brute force algorithm is the most intuitive approach to the string pattern-matching problem. This algorithm attempts simply to match the pattern in the target at successive positions from left to right. If failure occurs, it shifts the comparison window one character to the right until the end of the target is reached.
