[Bug-gnubg] Rollout bugs (j.s.d. options)

[Christopher D. Yep]

Windows version 0.14-devel 1.1227 030727 (build Jul 27 2003)

Settings --> Rollouts --> General Settings

Suppose I want to rollout 8/5 6/5 and 24/23 13/10 for an opening 3-1.

Suppose I check both boxes under "stop rollouts of multiple moves based on 
j.s.d."

(BTW, can anyone explain the intended behavior when one but not both boxes 
are checked?)

Set minimum trials to 36 and "No of j.s.d.s from best move to .001"

Then set-up the position, press CTRL-H to get a hint window, and select 8/5 
6/5 and 24/23 13/10 to rollout.  gnubg should then rollout each 36 
times.  Actually gnubg rolls out each 37 times (bug #1).

Bug #1: If I set minimum trials to N, the actual minimum trials is N+1.

Also, what is the intended behavior if I check the box under "Stop when 
result is accurate" as well as both boxes under "stop rollouts of multiple 
moves based on j.s.d."?  Does it stop the rollout when either condition is 
satisfied?  Also, what is the minimum number of trials?  The minimum number 
contained in "stop when result is accurate" or the minimum number contained 
in "stop rollouts of multiple moves based on j.s.d."?

Bug #2: When either box in "stop rollouts of multiple moves based on 
j.s.d." is checked, if I then select only one move to rollout from the Hint 
window, gnubg will only do 1 trial.

Minor Bug #3: Even if I don't check any box in "Stop when result is 
accurate" or "stop rollouts of multiple moves based on j.s.d.", when I 
click "Ok" gnubg reports that "Rollouts can stop..." and "Rollouts may 
stop..." when these conditions are met.  (However gnubg correctly ignores 
these conditions in its rollouts, thus the above is just a "cosmetic" bug.)

Minor Bug #3a: If I set the Ratio (Std. dev./Value) criteria to X, gnubg 
will report in the message window "less thanX for every value..."  Add a 
space between "than" and X.
