Add option to specify ForwardDiff chunk size about nlsolversbase.jl HOT 4 OPEN

if i remember correctly, the constructors accept a chunk keyword:
on OnceDifferentiable:

from nlsolversbase.jl.

Yes if you define the objective type yourself it is possible. I supposed OP is asking for this to be a keyword for optimize?

from nlsolversbase.jl.

Hi, I did indeed wish for it to be available in optimize. However since then I think I have a better understanding of the functionalities of the packages, and it is possible to use optimize with a OnceDifferentiable of TwiceDifferentiable function, which accept this option, so it indirectly solves the problem. Perhaps a heads up in the doc of Optim.jl could let users know about the possibility to use OnceDifferentiable or TwiceDifferentiable functions? Otherwise feel free to close the issue.

Yeah, I had originally chosen not to focus too much on this because I wasn't sure whether or not I wanted users to use them directly :) But it would solve the problem for now. I do think that it makes sense to allow for chunk size to be et in optimize as well though.
