I'd like to see 30 minutes per side, since
that's pretty typical for human games.
I'd like to see 10 minutes per side, obtaining an accurate
rating more quickly, although I realize that shorter times are
less suited for MC based programs.
Is it an o
Do you know how long is the average 19x19 game? Since territories are much
larger, I think it would take many more moves to get down to single point
eyes. 9x9 has 81 points, but averages 107 moves. I guess 19x19 would
average 500 or 600 moves.

I'd like to see 19x19. No one plays the game on any other board size than
19x19, so the other sizes are not very interesting. The current strong
programs are all tuned only for 19x19, and the patterns and strategy are
quite different at other board sizes.
Of course you should keep the 9x9 serve
There's still plenty of juice left at boardspace, so

Did you have a specific size in mind?It seems like a 19x19 server
would be the natural thing.
I could run the old server until I get the new one finished.

I don't have specific plans to set up 19x19 but the server can handle
any board size. The 9x9 server exists because Dave Dyer gave me space
on boardspace.net.
I'm actually working on an enhanced server - when It's ready I will put
the word out on the group and perhaps I can get someone to host it
A few months ago I suggested a number of stepwise increases
in board size to see how the algorithms scaled. It seems to me
having just 2 data points does not say enough about how the
MC (or any other) algorithm scales, so I wanted to be able to
graph some measure of strength against increasing bo
Hi Don,
Clearly UCT and monte carlo is very well suited to 9x9 go. It works much
better than the traditional computer go algorithms, and it is much, much
simpler.
Do you have any plans to set up a CGOS server for 19x19 go? I'd like to see
how well UCT/MC scales to 19x19 go. I don't think it w
Big thanks for claryfying that.

Yes, I think so. It's probably the name that was used at that time. I'm
not sure about the union-set. There was a discussion about a tree-like
structure supposed to achieve good performances. It was somewhere
between 1992 and 1994. At that time I was writing my PhD thesis and I

Hello all.
I've been lurking on the list for a few years now. In amongst the usual musings

If You merge two groups just add pseudo liberties.
