fmincon options playing



Hi,
I'm trying to make my fmincon optimization more efficient by playing
around with the options, ie. seeing how loose I can make them and
still get a good answer. There are 5 things I am playing with
TolFun,
TolCon,
MaxIter,
MaxFunEvals,
and
the number of times I loop the entire routine (I have the
optimization in a loop where at the end I take the minimum over all
the iteration results).

Is there any convention for doing this. I want high accuracy, so I've
set my tolerances around 10^-15 to 10^-17. MaxIter and MaxFunEvals
are at 10^5. Then there's the loop. Are any of these values
ridiculous? Are they reasonable? I guess what might be most helpful
is a short breakdown of how these options work.
I assume that tolerances definitely increase the processing time
(more than the rest of the options?)
The loop seems like a fast way to go? (i.e. many loops)
Which one (tolerances or loops) would be the better one to make the
dominant part of the routine?
I don't know how MaxIter and MaxFunEvals affect the processing time.

again, is there any method to finding the best set of options? What
should I be looking for? e.g. consistent results and quick processing
time?

Thanks

max
