Congrats Remi!
Beating Zen was very impressing.
I was also impressed Fuego's performance.
Fuego used 1024 cores with df-UCT + TDS. It did not work first day,
but it worked in final and beated MFG and Nomitan.

When Pasky arrived at Narita Airport, he happened to be asked from
TV "Why did you come to Japan". And TV followed him while the
tournament. He will be on TV in Japan.

I was surprised many MC programs are not UCT anymore.
UCB = (wins / games) + C*sqrt( log(all_games) / games )
But in MFG, CS, Pachi and Fuego, C = 0. So they use something like this.
UCB_RAVE = (1-beta)*(wins / games) + beta*(rave_wins / rave_games) + somebias.
Yoshizoe and I wrote Computer Go book last November.
I'm afraid it is in Japanese though.

Congratulations to Rémi and Crazy Stone!
Thanks Martin. The attached game is really funny. Looks like both Fuego and
Nomitan overlooked B's T10 and Fuego found it first. Nomitan would have won
if it played T17. I'm impressed by Fuego's fighting spirit throughout the
whole game.

Congratulations to Rémi!
MP-Fuego played on 1024 cores of the Hungabee system at University of
Alberta today.
It beat PerStone in the first round, lost to Zen in the second, won
against Many Faces in the 5th-8th place group and beat Nomitan in a wild
last game. A few moves before the end, Nomitan had over 90% win rate but it
suddenly swung the other way and resigned. At the end there are two semeai
involving ko on the board, one of them quite complex, and it is far from
clear what would have happened if the game had continued. I attach the game
so you can make up your own mind about it :)
