Split NLPModels #199

Closed abelsiqueira closed 4 years ago

abelsiqueira commented 5 years ago

I'm trying to rebase PR #187 and other 6 parts of #166 (Complete update of NLPModels.jl) and I'm finding very difficult to update everything because of the large amount of code. This happens on a smaller scale, for instance, when we decide to create a new function, which needs to be defined for every single model.

I don't remember the reasons to join NLSModels.jl here, but know I'm thinking that maybe we should split a few packages for easier maintainability. Considering that releasing packages is a lot easier know, this seems feasible by always keeping lower and upper bounds on the versions. Secondary less used packages can be updated in a later date.

NLPModelsJuMP.jl and CUTEst.jl are examples of how things will be after the change.

Parts suggestion:

@dpo, what do you think?

One disadvantage is that NLPModels.jl will not be able to define any easy models, only models that define all needed functions, such as HS5. We could keep ADNLPModels to prevent that.

After discussing it, we decided not to split anymore.
