makebearoff $Revision: 1.17 $ on Windows 2000.
I am using the command:
C:\GnuBg>makebearoff -o 10 -f gnubg_os10.bd
Getting up to about 800000 takes very little time, but the output slows to a
crawl at around 80000 to 90000.
Nardy warns that it may take several hours to generate each gnubg_os.bd (118
Mb) and gnubg_ts.bd (70 Mb). The latter took about 1 hr to generate on my PC,
so I'm expecting gnubg_os.bd to take only about 1.5 hours.
I left one going overnight and got this far:
909500/3268760
04/12/2002 09:12 7,274,496 gnubg_os10.bd
04/12/2002 09:12 20,439,040 t026453.bd
I started another at lunchtime and have got here in over 4 hours.
901300/3268760 (hasn't changed while I've been writing this email.)
04/12/2002 12:18 7,208,960 gnubg_os10.bd
04/12/2002 12:18 20,242,432 t004335.bd
(I note that the output always ends at a round hundred. Is this a problem or
just how often the screen is updated?)
I can't imagine why the output should slow down so much. I assume that the
program looks up the values of the possible resulting positions in the database
and averages them out. Obviously there are more possible positions to examine
as the number if chequers and points grows, but I wouldn't imagine it to cause
this amount of slowdown.
Is something going wrong, or am I being too impatient?
