Re: [Bug-gnubg] Why does it move first about 80% of the time UPDATE

[Wayne]

Ralph,
I am still finding the distribution is not 50:50 on the initial roll, but have  
observed a significant change when I set the dice option to www.random.org.

I note something from my systems engineering: Nancy Leveson at MIT states it is 
impossible to verify that software provides a safe outcome.  Other human 
factors / systems engineering researchers note the need to keep humans in the 
decision loop for the same reason.  Numerous anecdotal reports have also found 
bias in complex software (if it does not pass Turing test, it is not AI).  

Cheers


Wayne

Hi Wayne,

Over how big a sample of starting rolls is that 80% measured?
Also, see

for a tip on changing the method of rolling dice.
