I just noticed that several pieces of data have recently disappeared
from rollouts of cube decisions:

Try rolling out a cube decision and using copy in the analysis window
- you don't get the win/win gammon/win bg statistics. If you export an
analysis, you do not get any information about the rollout that was
done, the number of trials, the rollout settings, or much of anything
except the equities for double/no double.

I see nothing like with the Feb 10 version (copy in the analysis window or export in text, on Unix).

On the other hand, there are some little bugs, but nothing new :

Full cubeful rollout with var.redn.
71 games, Mersenne Twister dice gen. with seed -499332254 and quasi-random dice
Stop when std.errs. are small enough: ratio 0.1 (min. 72 games)

Why 71 games when the minimum is 72. Did it do 71 of them or is the bug in the display ?

Why "when std.errs are small enough" when I chose the JSD stop criteria ?
