Ok here we go,
Probability:
change of mutation % is how often the 'change of probability' happens
exponential is set default to 10 ^ (1 /1 )
This means that on reproduction the rates can get multiplied by 10 or divided by 10 for this specific robot.
liner is set to zero
This means that on reproduction the rates can get added by 0 or subtracted by 0 for this specific robot.
Mean / Stddiv changes the "mean stddiv" values instead of the probability values.
What to change is only liner, and changes the 'what to change' value
The interval for point mutations is the interval at which these are being done for point mutations (for point mutations it is not happening on reproduction, it is happening every time the interval is reached based on age)
edit: I would love for some one to write a proper wiki article on these...
What overflow error?
