Some of it could be the difference between 3.6 and 3.7.x. We use 3.6 at
level 10, but I do not know the default playing level of GNU Go on KGS.
We also originally put SlugGo up on KGS with a bug that had just been
introduced to the code (part of a quick hack to allow reasonable play
on small boards), and at first SlugGo's rating dropped below 16 k
before climbing back after we fixed it. On KGS they are both very close
to 13k, GNU Go about 1/2 better, SlugGo about 0.2 lower. I think that
they will get closer as more games build up.
I do think some recent work on GNU Go has made it stronger, but there
are reasons we do not use the development branch: we want to explore
what our changes are doing and we would not be able to separate the
effects if we were always changing the underlying engine, so I think it
is better if we wait for release versions of GNU Go and let the
development team decide when that version is ready.
My claim of being about 2 stones stronger than GNU Go is based upon
comparing results against the independent reference of Many Faces of
Go. It could also be some quirk that makes SlugGo stronger than GNU Go
against Many Faces but not against humans. We will know more as results
accumulate.
Cheers,
David

I played Sluggo last night on KGS, and noticed that it uses Gnugo 3.6;
but I believe there are Gnugo 3.7.x bots on KGS.

This is one of the questions explored by SlugGo, a cluster-based
program being developed at UCSC. Our answer so far is that we can
get about 2 stones stronger with 16 to 20 CPUs.
Hi David,
How do you explain that SlugGo has a lower rating than GNU Go on KGS ?
