Hello.
Thank you for recommending LevenbergMarquardtOptimizer. It works for
our
function. However, it seems to take much longer than BOBYQAOptimizer.
Is
this expected as it needs to compute gradient?
It's difficult to tell.
Someone listening here might provide some theoretical insight.
But if you suspect an implementation problem, it would be a good start
to post[1] a stripped-down version of your code (preferrably in the
form
of a Junit test).
Regards,
Gilles
