Hill climbing cipher
WebThis page describes an automated technique for breaking substitution ciphers using a hill climbing algorithm. Cryptanalysis of the Straddle Checkerboard. The straddling checkerboard is a substitution cipher, except that the substitutions are of variable length. It has formed a component of several impotant field ciphers, the most notable being ...
