Each division four-round Swiss.
The first round started at 08:00 UCT for the Formal and 08:10 for the Open division.
As usual, the tournament was held in two divisions, Formal and Open, with more restrictive entry conditions for the Formal division.
Formal Division 19×19
Open Division 19×19
The "real" names of the bots listed above, and of their programmers, are listed here: programs which have registered for KGS Computer Go Tournaments.
I was wrong. GNU Go won the formal division, beating CrazyStone. Unfortunately it was never drawn against MoGo. In the Open division, a modified version of GNU Go (MonteGNU, which includes some MC code) beat MoGo, and lost against StoneCrazy, and all three programs ended on three wins.
In round 1 FirstGoBot passed early in its game against MoGoBot. This indicates some kind of bug, which we hope can be found and removed.
Before the event started, I removed IdiotBot, to make the numbers even and avoid byes.
In round 3, when MoGoBot19 played the circled move K18 (see diagram at right)
against StoneCrazy, StoneCrazy failed to notice that it could save the eight triangled
stones by capturing five white ones, and instead played at L10. Had it made the F18
capture instead it would probably have won the game.
StoneCrazy's auther Rémi Coulom commented at the time "The capture at F18 was pruned... Should not be too difficult to fix." However he later wrote to me, "In fact, the capture at F18 was not pruned. But White extension at F18 after Black L10 was. The reason is that F18 is a Ko shape."
So there is still room for significant improvement in this UCT program. And despite its making mistakes like this, it has (playing as CrazyStone) a rating of 2k on KGS, and has had a 1k rating.
Also in round 3, Orego2 was winning a close game against SimpleBot when it vanished, and eventually lost on time to SimpleBot.
In round 4 Orego2 was still missing, so its opponent StoneCrazy won by default.
