Type AbstractOptimizationAlgorithm not exported

[awage]

Describe the bug 🐞

The docs for solve define the type for the problem solver:

solve(prob::OptimizationProblem, alg::AbstractOptimizationAlgorithm, args...; kwargs...)

But the type is not exported by the package

Optimization.AbstractOptimizationAlgorithm

ERROR: UndefVarError: `AbstractOptimizationAlgorithm` not defined in `Optimization`

It is not a critical bug but I wanted to use the abstract for dispatching on a problem. I have a workaround but it is just to let you know this unexpected behavior.

Thanks for the package!

I don't think it's intended to be exported. But OptimizationBase.AbstractOptimizationAlgorithm should work fine? We can mark it as public API (need to define its interface though) but it definitely isn't needed to be exported by default.

It isn't defined either in OptimizationBase:

OptimizationBase.AbstractOptimizationAlgorithm
ERROR: UndefVarError: `AbstractOptimizationAlgorithm` not defined in `OptimizationBase`

As I understand it, all methods in the Optimization.jl subpackage should be concrete subtype of AbstractOptimizationAlgorithm. I have no idea what the default interface should be like. It looks like a big pain of implementing this in all packages for a small gain. And also it is unimportant for my application.

But if you consider it an improvement I can try to draft a PR.

I had a look at the internals of the package and its much more complex than I though.

Sorry it's SciMLBase. AbstractOptimizationAlgorithm. But yes, this library is due for a refactor and I plan to do it this summer.

Thanks! I'll close this issue.
