In computer science, pattern matching is the act of checking a given sequence of tokens for the presence of the constituents of some pattern. In contrast to pattern recognition, the match usually has to be exact: "either it will or will not be a match."

An alternative classical linear-time pattern-matching algorithm is due to Boyer and Moore, a few years later than KMP. Unlike KMP, the Boyer-Moore algorithm starts matching the pattern from the last symbol rather than the first, allowing it to make big “jumps” if no match is found.

Matchmaking is the process of matching two or more people together, usually for the purpose of marriage, in which case the matchmaker is also known as a marriage broker.
