String search algorithm

In computer science, string-searching algorithms, sometimes called string-matching algorithms, are an important class of string algorithms that try to find a place where one or several strings (also called patterns) are found within a larger string or text. A basic example of string searching is when the pattern and the … See more The most basic case of string searching involves one (often very long) string, sometimes called the haystack, and one (often very short) string, sometimes called the needle. The goal is to find one or more occurrences of the … See more Naive string search A simple and inefficient way to see where one string occurs inside another is to check at each index, one by one. First, we see if there's a copy … See more • Sequence alignment • Graph matching • Pattern matching • Compressed pattern matching • Matching wildcards See more Classification by a number of patterns The various algorithms can be classified by the number of patterns each uses.

In such cases you need to parse every file to find best possible files that matches. One uses algorithms like Boyer Moor algorithm. See this and this for details. This is also equivalent to grep ...

CAM can match a huge number of patterns simultaneously, up to about 128-letter patterns (if they are ASCII; if they are Unicode only 64). And it's one call per length of letter in the string you want to match to and one random read from memory per length of the max pattern length. matthew 12:36 niv

Rabin–Karp algorithm - Wikipedia

WebThe most straightforward algorithm, known as the "Brute-force" or "Naive" algorithm, is to look for a word match at each index m, i.e. the position in the string being searched that corresponds to the character S [m]. At each position m the algorithm first checks for equality of the first character in the word being searched, i.e. S [m] =? W [0]. In computer science, the Boyer–Moore string-search algorithm is an efficient string-searching algorithm that is the standard benchmark for practical string-search literature. It was developed by Robert S. Boyer and J Strother Moore in 1977. The original paper contained static tables for computing the pattern shifts without an explanation of how to produce them. The algorithm for producing the tables was published in a follow-on paper; this paper contained errors which were …
