The needleman and Wunsch algorithm for global alignment
Needleman and Wunsch (1970) proposed a maximum-match pathway that can be obtained computationally by applying a straightforward algorithm. In its simplest form, cells representing identities are scored 1, and cells representing mismatches are scored 0; the 2D array is thus populated with these values.
