Let a textstring T of n symbols from some alphabet and an integer m < n be given. A pattern P of length m over is sought such that P minimizes (alternatively, maximizes) the total number of pairwise character mismatches generated when P is compared with all mcharacter substrings of T . Two additional variants of the problem are obtained by adding the constraint that P be (respectively, not be) a substring of T . Effacement sequential algorithms are proposed in this paper for the problem and its variants. Key Words: Design and analysis of algorithms, combinatorial algorithms on words, pattern matching, inverse pattern matching, Hamming distance, digital signature.
