Hi,
I'm attempting to understand when and how I would want to use the
ParameterValidator WRT LevenbergMarquardt problem construction.
Anyone
have any stories they can share?
It is possible that the optimizer wants to try a certain value
for an optimized parameter that entails a constraint on another:
the validator can attempt to reconcile them. It might be better
to return a different point rather than fail.
So how do I recognize this scenario and put in place a
ParameterValidator that is appropriate? What is the event that
causes
the validate method to be triggered?
When the corresponding argument is not null (at "problem" creation),
the point (set of optimized parameters) is always validated before
evaluation.
What point the "validate(RealVector)" returns is up to user.
