[Bug-gnubg] Rollouts - some bugs and suggestions

[Magnar Naustdalslid]

Again, thanks for this excellent program. I am using gnubg February 15 2003 
build, 
snapshot 030303 and I am happy to see that the weird "train" menu has been 
removed :-
).

Here are some rollout issues I hope you will consider:

1. Will it be possible to do cubeless rollouts with cube-adjusted equities? 
Sometimes I 
don't trust gnubg's cube-handling in rollouts with live cube (for example if it 
doubles after 
one move, but not after the other, even though I expect a double in both 
cases). 
Currently, cubeless rollouts yield only cubeless equities, right?

2. When I analyse a match and do a rollout for a double/take decision, I have 
to do this 
BOTH for the doubling decision and for the take decision. It should only be 
necessary to 
do one rollout.

3. When I uncheck "Cube decisions use same settings as Chequer play", "Use same 
settings for both players" or "Use Player0 settings for truncation point", the 
changes are 
not saved. 

4. If I use expert level for checker play and world class 33% reduction for 
cube play, next 
time I open rollout settings cube play has changed to 25% reduction.

5. It seems to me that not much time is saved by using using a high level of 
play for the 
first few plies and expert for the remainder as compared to using a high level 
for all the 
moves. For example, if I choose world class for the first five plies and expert 
for the rest 
of the game, I would expect this to be MUCH faster than world class for all the 
moves. 
This does not seem to be the case. Maybe I am missing something.

Keep up the good work!
