hello! trout again. i’m gonna try to get this to #1 haskell engine, but it’s been such a pain…

after summer of making I did some more work on this, but hit a wall where all my changes either did nothing or gained like 10elo (which is not enough for the hundreds i need). I tried rewriting part of search but hit a wall again with the same problem, on features that should have made improvements!

i’ve been fighting with the search some more trying to get reverse futility pruning to do something meaningful. in someone else’s engine, it gained i think 80+ elo in total (!!!), which is bonkers compared to the 20 or something i get on a good day. it’s not a good day, so RFP actually manages to lose elo here.

i might have to rewrite search again. i don’t know how much of this is just wrong.

(here’s the commented out old search)
