The bitap algorithm (also known as the shift-or, shift-and or Baeza-Yates–Gonnet algorithm) is an approximate string matching algorithm. The algorithm tells whether a given text contains a substring which is "approximately equal" to a given pattern, where approximate equality is defined in terms of Levenshtein distance – if the substring and pattern are within a given distance k of each other, then the algorithm considers them equal. The algorithm begins by precomputing a set of b… WebNov 7, 2024 · Shift or Algorithm (Bitmap Algorithm) Applications of String Matching Algorithms: Plagiarism Detection: The documents to be compared are decomposed into string tokens and compared using string matching algorithms.
