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 searched text are ... WebIn real world KMP algorithm is used in those applications where pattern matching is done in long strings, whose symbols are taken from an alphabet with little cardinality. A relevant example is the DNA alphabet, which consists on only 4 symbols (A,C,G,T).
