Subject: | [Bug-gnubg] GNU backgame eval + bug |
Date: | Sun, 6 Oct 2002 14:49:44 -0300 |
From
a post in Gammonoline with Position ID: 2LYBCDPOewMAAA --------------------------------------------------------- On
SW 4's best setting, 3ply/precise. 360 rollouts give a cubeless equity of .565
+/- .023. (I'll report back when 1296 are finished in a few days as time
permits) This
position is a double and a clear take. The market will be clearly lost if the 6
point is cleared. Anyhow..lets look at some bot cubless evaluations on their highest
settings (except GNU where I will look at different plies) SW
4 .549 WOW..close to the result like it is supposed to
be. SW
3 .773 WOW..it incorrectly thinks this is a BIG pass. JF
.760 and also passing incorrectly and underrating this fine backgame. GNU
is acting funny as there's a bug in the cubeless equity presentation(it
doesn't add in G and BGs) so I'll just calculate it. 0 ply .573
, 1 ply .819 . 2 ply .636, 3 ply .825 , 4 ply
.607. Apparently
GNU 4 ply is seeing enough hitting variations but why is 0 ply right on and 1
and 3 ply way off ? Anyhow, from playing around with
GNU I will state that I think it could use some more training in backgame
aspects. GNU certainly has the potential to become the world's premier BG bot. Note
that SW 4 1ply thinks this is .504 cubeless which is overvalueing the backgame
which I am seeing, at times, IMHO. ..neilkaz.. |
