Actually, C4 is not [cd]. C4 is actually [cf] on a 9x9 board. It's something
else on a 19x19 or 13x13 board. The row character depends on the boar

CGOS uses Tromp/Taylor scoring exactly.
That means if a stone is still on the board it is alive.
Games must be fully played out.
The cgos main page discusses rules and such.

Don,
Does CGOS count stones in atari as alive or dead?

Sylvain,
I had a similar issue where pthread/gcc/cygwin combination produced a very slow
application. I had better success with Visual C++ and Boost (for portable
threads).
Where and when can we read your paper?
Thanks for releasing a binary version of MoGo to the community!

Can someone recommend a good paper on distributed alpha-beta searching? Not
necessarily for Go; I'm just interested in reading up on the subject.

Sounds like a great opportunity for parallelization too.

I've always thought about it as professionals trying to playing on the
"edge-of-chaos." Go is an interesting game in that regard since at least early
JIT didn't solve everything - the managed memory management in Java (and C#)
has overheard which JIT can not always optimized away, for example.

Does anyone have an example where "pass" is the best move, and not part of the two passes to end the game? I'm trying to determine if passes should ever be considered in a search for the best move, and if so, how to exclude them until it is really necessary.
Thanks,
