Ninth KGS Computer Go Tournament

Sunday December 4th, 2005

Rules

19x19 board
Chinese rules, komi 7½
58 minutes each absolute time

Format

Swiss

Times

The first round started at 08:00 GMT for the Formal and 08:10 for the Open division, subsequent rounds started at thirty-minute intervals.

Results

The tournament was again held in two divisions, Formal and Open, with more restrictive entry conditions for the Formal division. Essentially, an entrant to the Formal division must not contain move-generating code used by any other such entrant, and its author's real identity must be known. A program may enter both divisions simultaneously (though it will have to use different names for each).

The "real" names of the bots listed above, and of their programmers, are listed here: programs which have registered for KGS Computer Go Tournaments.

Description

Fortunately for the tournament organiser, only two games ended in arguments between the bots. Rrecords of these "forfeited" games are now available below.

In this tournament, we welcomed another new program, Stephen Jay Guy's ToBog, which played only in the Open division. The official KGS results pages also show Olympus as having played; this is the consequence of a mistake. The results tables above (unlike the KGS ones) have been corrected so as to count games against Olympus as byes.

Formal division

It was good to see Gopp (Go++) playing, after its unfortunate accident with a carpet-layer two months ago. It was the undefeated winner, but two of its games were close: it beat Dar51 (an experimental version of Dariush) by 3½ points in round 1, and GNU (GNU Go) by 4½ in round 3. GNU also achieved three wins.

Open division

IndigoBot2 was the undefeated winner. Dariush sored three wins out of four, its loss being on time, to WeakBot50k, in round 1, in a position in which all of its opponent's stones were dead. CrazyStone also achieved three wins.
