The 21st Century Cup Computer Go competition was held in Edmonton Canada,
on July 27 and 28, 2002. There were 14 participants and 7 rounds.

Results are:

1. 7-0 The Many Faces of Go
2. 6-1 Go 4++
3. 5-2 Go Intellect
4. 4-3 Katsunari
5. 4-3 Aya
6. 4-3 Neurogo
7. 3-4 Gnugo
8. 3-4 Explorer
9. 3-4 Smart Go
10. 3-4 Indigo
11. 3-4 Great 5
12. 2-5 Golois
13. 2-5 TSGO
14. 0-7 Hiratsuka

Neurogo's result is very impressive since it is a self-trained neural net with minimal reading.
Lack of reading hurt it in the game against Many Faces, where it lost by 145.5.

Against Go 4++, Many Faces played slower moves in the middle game and fell behind, but
invaded the center territory and killed a group to win.

Against Go Intellect, Many Faces gave a couple of large targets for attack, but Go Intellect
attacked too hard, and Many Faces ended up killing one of its groups to get the lead. In the
late endgame, Go Intellect made a simple life and death error and another group died, so it
resigned.

Katsunari miscounted liberties in a semeai against Many Faces and lost by 128.5. Many
Faces's closest game was a 27.5 point win against Aya.

The games between Many Faces and Go 4++ and Go Intellect are attached. All games will
be available soon on the 21st century web site.
