[SciPy-User] OT: global optimization, hybrid global local search

I'm looking at nonlinear regression, function estimation again.
I'm interested in combining global search with local optimizers, which
I think should be much faster in many of our problems.

Anyone with ideas, experience, code?


I just searched and browsed a few papers, but it's not my specialization.

"In particular, the problems which are very hard to be solved by gradient
descent-based methods, or the ones which have computationally
expensive objective functions are very good candidates to be solved
by the proposed methods."   *)
