My analyzer put the correct type in first place, but my hillclimber was unable to solve it without the crib. I solved it by key searching using the crib. It’s one random sentence from Gutenberg.org, but the last two words are cut off. The crib is: SVXLIGSPHWYR

  1. The passage continues YMJBNSYJWSTTS

    I used converging key search with the new route selection grid. That helped in narrowing down the routes to just two. My original word list did not have the correct key words, but it’s highest score occurred with the correct two routes. I used those two routes with a bigger word list and got the solution.

    1. I tried converging keys originally, and the words were in my lists, but that particular program did not try all routes, and did not include one of the correct routes. It gave me some good exercise in using paper and pencil to get some keyword data from the crib. I can generate lists of possible keys from a polybius key program that does check all the routes.

  2. In case anybody can use them I’ll paste in the routes from the grid at the bottom of this post. They are in json format. I think json is the most popular format for data these days. “routes” is an array of 5×5 routes, “routes6” is an array of 6×6 routes, and “route_names” is the corresponding array of route names.
