The only reason that SlugGo is not on 19x19 CGOS is that we are working
towards a version that does something different than the version that
was
running a year ago.
When we have the new features running we will begin playing there.
It is my opinion that 30 minutes per side is common for human tournament
games, and thus makes sense for 19x19 CGOS. I think 10 minutes is rather
restrictive, so maybe 20 minutes makes sense.
Cheers,

I think there are two reasons there are not more programs on 19x19
CGOS:
1) The anchor, Gnugo, is quite strong, Many Faces 12 is stronger, and
CrazyStone is much stronger. Since the programs playing are so
strong, it
is demoralizing for a new program to lose so often. Without weaker
competition, it is hard to get accurate ratings for new, weaker
programs.
2) The rounds take almost an hour, so it takes much too long to get
enough
games to see how your program is doing. In my local testing, I use
10 or 15
minutes per side. I like to see 50 to 100 test games get any
confidence
that a new version is stronger. I prefer to get a test run
complete in
under a day.
I propose the following changes:
I'll put up 3 weaker versions of Many Faces 12, so there is
competition at
lower ratings. These versions are quite fast, using only a few
seconds for
a full game. This will provide some stable opponents for the weaker
programs.
I think the time limits for CGOS19x19 should be reduced to 10 or 15
minutes
per side. This is enough to test programs, and it's still a
reasonable time
limit for games against people. Since programs that search scale with
additional time, the relative ratings of these programs should be
similar at
10 minutes per game and 30 minutes per game.
