I like this article a lot, but if I can put forward one mild criticism, it seems to depend entirely on having exactly the same measure of semantic distance for word pairs as the original generator. In that case, as the post shows, you only need several guesses to eliminate all possibilities other than the correct one, just like you only need a few GPS satellite locks to pin down your location.

It would be interesting to see a solver that works more like a human player, where it requires the "warmer" "colder" information from different guesses to hone in, rather than being able to simply look up which words have the exact semantic distance (+/- some fudge factor) from the guess.
