$5000 buys a lot of processing power these days. It's easily enough for a
32 core cluster.

Just to clarify, Pachi has two

Maintaining the patterns is trivial. Using them is expensive, if the
patterns have weights, since you have to build a probability distribution
over the full board. Crazystone divides the board into rows and columns to
speed this up. I do something different in Many Faces. I'm not sure what

Darren,
might there be sufficient interest to arrange to have the games live on
IGS?
We plan to have the games live on KGS.

usually the top two London Open games are live.

Taking time to do it right saves having to do it twice.

Thirteen years ago John Tromp bet that he wouldn't be beaten by a
computer before the end of 2010, and I took him up on that. The story is

We now have a date and a venue: the match will take place in London at
the very end of December. Thanks to the British Go Assoc
