Re: [gnugo-devel] interfacing to gnugo

Hi

This sounds very interesting.
I can answer the easy questions, and let the hard ones for the gurus ;-)

Yes. With the same seed gnugo will always give the same move/game.
On command line it is the --seed 12345 parameter

Hmm not sure i understand. The score can vary from -361 to +361 +/- komi and
prisonners ;-)
Gnugo uses optimistic_score (win all) and pessimistic_score (lose all). 
It always considers the score from its color point of vue (positive
is win)

But don't forget gnugo is "sometimes" just wrong at life and death...
(especially for groups floating in the center and surrounded at some
 distance)

I'll wait for the publication. Go on :)
