WebDec 24, 2014 · Hill climbing is a mathematical optimization technique for the purpose of local search. This iterative algorithm starts with an arbitrary solution to a problem, and later on, it attempts to find a better solution by incrementally changing the elements of the solution one by one. WebThere are several algorithms available which can attack a Playfair cipher. Hill climbing might be one option. Basically it starts with a random key (assuming it's the best one) and decrypts the cipher. The resulting clear text is scored using a fitness function. citizens advice jobs norwich
