I think it's now well known that Mogo doesn't use UCT.
I realize that i have no idea at all what Mogo do use for
it's MCTS.
There are only two things i dislike about UCT :
- It's slow to compute.
- It's deterministic
I really wonder if there was an article describing
the new MCTS of mogo somewhere that i missed.
How is it better than UCT ?
My understanding is that MoGo dropped the upper confidence bound
portion. That makes it a bit faster, but still deterministic for a
given set of playout results.
Heuristics and RAVE give a sufficiently good move ordering that less
exploration is needed. IIRC, Valkyra still uses UCT, but has a very
low coefficent on the upper confidence bound term.
