A little ditty that plays by doing random rollouts from it's root position and nothing else
http://op12no2.me/toys/roller/play.htm
USES ONE CORE 100% FROM WITHIN YOUR BROWSER WHEN MOVING.
Will prob evolve mcts etc but keep strict 'absolutely no semantic knowledge' rule.
I'm getting about 3.5kr/s at the start of the game on my work pc, but as a one-evening hack of lozza i'm sure that can improved a lot!
ps: I'm including KK, KN, KB draws as 'rules'; debatable I guess.
pps: It's missing 3 fold rep. I cannot think of a way to do it without hash but want to KISS.
My niece loves it over Lozza

Similar to yours. Finally, an engine I can defeat.

This particular game makes me feel like the engine is broken, not just weak. It went through 58.25 kr and it wasn't able to avoid mate in 1...

Re: Roller (just for fun)
lol, not quite ready for tcec yet then but it's a lot of fun avoiding semantics.
re: mate in 1 - yes i would expect it to handle that - i'll have a fiddle...
ps: you can also pass it a fen and play from there (interactively generate the fen using the debug button), e.g.:-
http://op12no2.me/toys/roller/play.htm? ... 0%201&t=10
good for testing.
it also locked up on me earlier - a stalemate thing i think - stalemate really slugs kr/s at the moment. i need to figure out a cleverer algorithm.

Re: Roller (just for fun)
I did a tweak to start with short rollouts (2 ply!) and exponentially increase (x1.00003) from there to a ceiling of 200. this allows it to avoid close mates a bit better. If the ply limit is reached before W/L/D it tosses a coin and returns W or L.
It's playing a true random mover now (called RollerRandom of course) in arena (1s/move) and other than falling for 3-fold now and again, always wins; yay for Roller!
The latest version should eloquently announce itself as 201804201350, if it doesn't, click ctrl+F5 a few times until it does.
It's really really hard to resist adding even simple semantics but that would be cheating. It needs a syntactically based goal other than mate but I don't think there is one...
