[gnugo-devel] Question about scoring and endgame

[Marco Scheurer]

Hi,

I bundle GNU Go with a Mac OS X Goban application 
(http://www.sente.ch/software/goban). Some users complained that scoring 
takes too much time. What I do to score games is to launch a gnugo 
process, have it replay the game, and then issue the "final_status_list 
dead 2" gtp command.

A look at GNU Go's code showed that finish_and_score_game() first 
attempt to finish the game by playing alternative sides, then call 
aftermath_compute_score(). In turn, aftermath_compute_score will call 
do_play_aftermath(), which will again play out the game.

I suppose that the role of the first attempt to finish the game is to 
fill the dame, but nevertheless, I was wondering if it is necessary, or 
if one could get away without it. I made a few manual tests, with and 
without the first play out, but so far they are inconclusive.

Any advice welcome.

Thanks,

marco
