[math] LevenbergMarquardtOptimizer replacement

Hi,

 

I would like to use the LevenbergMarquardtOptimizer but it was deprecated in
3.1. It is listed in o.a.c.m.fitting.leastsquares in the latest development
API. However, I do not see an it listed anywhere in 3.1 or 3.2. I am
currently using 3.1 and I would like to know where I can find it or a
suitable replacement.

 

Thanks,

Patrick

No.
A new "fluent" API has been implemented for the class in the
"o.a.c.m.fitting.leastsquares" package.

[There have discussions to change to yet another API (see on the
bug-tracking system).]

Yes, but I am wondering if it had just been moved in the way many of the classes in optimization were moved to optim. Given that LevenbergMarquardt was deprecated in 3.1 and 3.2 only to reappear in the latest development version made me think it had just been moved somewhere.

[But it is deprecated, as you noticed.]
