WebBut it turned out that the program not only generated statistics, but to my surprise, it also solved ciphers! The basic idea is to allow a "fudge factor" in comparing the new key's score with the old key's score. In ordinary hill-climbing the basic step is: IF new_score >= old_score THEN. keep new key. set old_score = new_score. ELSE WebOct 21, 2016 · The basic steps are two-fold: Test different key lengths, and look for a length where the letters in each column look like they might plausibly be consecutive. Once …
