Added: February 09, 2010 | Visits: 831 Algorithm::AhoCorasick provides efficient search for multiple strings. Aho-Corasick is a classic (1975) algorithm for locating elements of a finite set of strings within an input text. It constructs a finite state machine from a list of keywords, then uses the machine to locate all occurrences...

Added: May 10, 2013 | Visits: 538 This SMAWK algorithm takes as input a function for computing matrix values, and searches for the position of maximum value in each row. The matrix must satisfy the "totally monotone" property: in each submatrix (in particular each 2x2 submatrix) the positions of the maxima must move leftward as...
