This is much better than the post in which you claimed that David only
invented Rave, thanks for correcting :-)

The other mistake in your posts is when you claim that "Crazy Stone's
contribution for the playout is of same/more importance"; CrazyStone's
contribution was great for the MCTS principle (and I've always taken care of
citing this big contribution to games/planning in my papers), but the real
progress for the MC part came from mogo I think - this is a bit Go-specific
(not completly),
but really important for computer-Go :-)   mogo's MC was implemented in many
strong programs, and influenced the MC of all other
strong programs. I think there's no exception to this. I was personally of
little influence on that, but I was here for clearly seeing that
this is a big contribution.

A third point you have not seen, I think,
 is that, when mogo was the only program with such a MC, it was really
stronger, I think, than other programs. After
the publication of the pattern-based method in the playouts, all programs
were nearly as strong as mogo - but there was really a time period during
which mogo was significantly stronger than other programs. When a
sophisticated pattern-based algorithm was implemented in MoGo's bandit and
RAVE values + mogo-influenced MC part was implemented in other programs,
equality was back between all strong programs - there are a few strong
programs without the big pattern-based method for the bandit part, which
probably makes a non-negligible difference, and nothing else in 19x19 (in
9x9 there's the opening book and the nakade...)...

My feeling for the future is that Drake's paper can have a lot of influence
(beyond computer-go). We'll see...

Best regards,
Olivier
