I tried pure MC + UCT + RAVE 10000 playouts on KGS.
It got 15k. (name is pureMcUct, but it uses Rave.)
Program playouts KGS CGOS(19x19) CGOS(9x9)
GNU Go classic 6k 1800 1800
AyaMC 600 6k 1741 1992
AyaBot classic 8k 1522 1750
pureMcUctRave 10000 15k 1380 1595
pureMcUct 10000 1081 1389
AyaMC is my MC program.
AyaBot is my old non-MC program.
pureMcUctRave is pure MC + UCT + RAVE.
pureMcUct is pure MC + UCT.
I was surprised there is big difference KGS rank and CGOS 19x19 rating.
AyaBot and pureMcUctRave's Elo difference is only 142(1522-1380), but
KGS rank difference is 7 rank (15k-8k).
