Hi there, I also posted this on GOL.
I've understood from Jim Segrave that quasi-random dice just discards
doubles for the opening rolls, effectively rotating 30 rolls.
However, I still have a question about this. Normally when I do a rollout,
I would get one complete rotation for the first roll when I set 36 trials.
Suppose I use 36 trials for the opening roll. Will it now try to rotate the
opening roll, find out after 30 trials that one rotation is done and start
another rotation for the remaining 6 trials that it can't complete? Or will
it use random dice for the remaining 6 trials?
Now, the same question for using 30 trials for the opening roll. Will this
in practice produce exactly one rotation of non-double rolls? Or will gnubg
think 30 trials is not enough for a complete rotation and just use random
dice then?
More realistically, what exactly happens when I use 1080 trials from the
initial position? Will this rollout recognize it can do a complete rotation
of the first two rolls (30*36)? Or will it think less than 1296 trials is
not enough for rotation of both rolls and just rotate the first roll?
What happens when one use 1296 trials? Will this give potentially skewed
results perhaps?
Any comments welcome, especially from the gnubg team. It's hard to find out
what gnubg does just by running tests here. Joern Thyssen's earlier
explanation doesn't mention rotation with 30 rolls instead of 36, so I have
some worries about what GNUBG exactly does here, and whether it's consistent.
TIA,
