They speak for themselves. Just wanted some feedback. I have a hunch (nothing more) that this solution is both wildly wrong, but also much closer to …
Line 10 suggests "zodiac loves …" Or perhaps, "Love, Zodiac".
I’ve always thought the last line seemed to suggest "Signed" from the middle zodiac symbol backwards to the left, and then "Zodiac"…
Transposition of the plaintext would make the cipher look fake in such a test. Agreed. Do you think it is also plausible to simply hand tweak a ci…
Period 2 bigrams are also missing. A 340 character 408 has 38 period 2 bigrams, though these are less likely to occur. Period 2 bigrams are 2 position…
What I like about the pareto optimality approach is that it helps get around the problem of knowing how important the tradeoffs are between different …

Your objective function uses 5-grams only? Any particular reasoning for that? Did you experiment with other n-grams, and find that empirically best?…
True. But we have to be careful about "back fitting" the observation to Zodiac materials. I agree. At this point it is a pretty thin thre…
Thanks, Jarlve. I like the idea about not changing all the occurrences of symbols involved with the word placements. Have you ever looked at multiobje…
Putting it another way: The chance of "BY" appearing 4 times is low. The chance of "OF" appearing 4 times is probably also low. …
Here is his evidence: -glurk Somewhat demotivating. But there may be one particular weakness to what he is doing here. He says "I have enc…
I did not see any source code for AZdecrypt, nor an algorithm description. Here is a basic run down. Load some 5-gram letter log frequencies into a …
Jarlve, do you know why simulated annealing works better with smaller changes? I also noticed that trying to do too much at each step seems to lead t…
4. Let’s face it: The 340 is extremely hard to crack. Either someone lands a ‘lucky strike’ (by guessing and using Oranchak’s webtoy or any other tool…
