Hello François,
For GNU Backgammon, at the time being, I only participate in person, thus
Adrian Wright (and the gnubg development team) should have the last word in
this one.
Yet I'd like to point out:
Longer matches and more matches played tend to favorite the strongest
player, as luck becomes less and less envolved.
Playing best out of 3 1-pointers shouldn't be the scenario for designating
Olympiade's Gold Medal Winner.
The previous scenarios had best out of 5 15-pointers.
I think best out of 3 11-pointers is a reasonable draw-back, considering the
expected playing time of your bot will exceed the playing time of gnubg and
BgBlitz by a factor X. And X might be?
Even playing at 4ply on an old Pentium Celeron IV 2GHz, gnubg moves within 5
minutes. Extremo or WorldClass settings - and even GrandMaster setting -
make decisions within 1 minute, allowing 1,000 moves withing the time window
of the 16 hours you forsee at the Amsterdam Olympiade.
Thus time isn't the issue for gnubg.
And talking about your bot: do I understand correctly it will play on-line
matches to define it's next move?
Greetings,
motiv4u
Nardy Pillards
