Update package #38

Open lostella opened 2 years ago

lostella commented 2 years ago

CI workflows fail since the package has long been unmaintained. In particular, I doubt it will support the latest ProximalAlgorithms versions.

Yes, adding latest version of ProximalAlgorithms will take some time. I'm not sure how many people is actively using this package anymore.

Wanted to elaborate my last comment here.

Historically the goal of this package was to provide a user friendly interface to the other packages present in the JuliaFirstOrder ecosystem.

Now that ProximalAlgorithms supports an AD like Zygote I feel like StructOpt has lost its initial scope. If it is about using matrix free operators (AbstractOperators) these can still be used easily in ProximalAlotithms.

I think it's time we retire this package and invite new users to use ProximalAlgorithms only. I say this with some sadness as of course I'm quite emotionally attached to StructuredOptimization. I still remember when it was called RegLS!

So instead of updating this package I'd rather put the effort on moving the demos to ProximalAlgorithms. Let me know what you think @lostella

I definitely agree on this: all the demos would fit nicely in the documentation for ProximalAlgorithms. Sparse deconvolution, line spectral estimation, audio declipping, total variation denoising… Maybe even an example of optimal control problem
