Hey,
 
            Is it correct if I state that the OptimizerScales have no
influence on the MaximumStepLength of the optimizer?  I would expect
that if the optimizer scale for a certain variable is set to <s>, and
the maximum step length is set to <l>, that the maximum step I can
expect would be <s*I>.  But what I see is that the maximum step is
always <l>, no matter how small <s> is.
 
Any clues?
Thanks,
 
 
Toon Huysmans.
