The National Institute of Standards and Technology (NIST) — known between 1901 and 1988 as the National Bureau of Standards (NBS) — is a measurement standards laboratory and a non-regulatory agency of the United States Department of Commerce. The institute's official mission is to promote U.S. ...
A string matching algorithm that compares string's hash values, rather than the strings themselves. For efficiency, the hash value of the next position in the text is easily computed from the hash value of the current position.
Industry:Computer science
A string matching algorithm that compares the rarest character first. When a character doesn't match, the next character in the text beyond the search string determines where the next possible match begins.
Industry:Computer science
A string matching algorithm that is a variant of the Boyer-Moore algorithm. It uses two consecutive text characters to compute the bad character shift. It is faster when the alphabet or pattern is small, but the skip table grows quickly, slowing the pre-processing phase.
Industry:Computer science
A string matching algorithm that turns the search string into a finite state machine, then runs the machine with the string to be searched as the input string. Execution time is O(m+n), where m is the length of the search string, and n is the length of the string to be searched.
Industry:Computer science
A string matching algorithm which builds a deterministic finite state machine to recognize the search string. The machine is then run at each location in turn. If the machine accepts, that is a match.
Industry:Computer science
A string matching algorithm which computes the shift value for both the rightmost character of the window and the character preceding it, then uses the maximum of the two values.
Industry:Computer science
A string matching algorithm which keeps an array of bits, R, showing if prefixes of the pattern don't match at the current place. Before searching, mismatch arrays are computed for each character in the alphabet and saved in an array, S. For the next position, with the character c, R = shift(R) or S(c). If the last bit of R is 0, the pattern matches.
