When you get this dataframe you can sort through it to get the problems that you want. For example, if you want to filter problems based on their size you can apply this filter:

filter_df = df[ ( df.nequ .≥ 50000 ) .& ( df.nvar .≤ 34000 ), :]

2problem-73-11032-preladybug92244337531106928

You can get the problem name directly from the dataframe:

name = filter_df[1, :name]
"problem-49-7776-pre"

fetch_ba_name returns the path to the problem artifact. The artifact will download automatically:

path = fetch_ba_name(name)
"/juliateam/.julia/artifacts/dd2da5f94014b5f9086a2b38a87f8c1bc171b9c2"

You can also get an array of the paths to an entire group of problems

path = fetch_ba_group("ladybug")

You can then evaluate the residual and jacobian (or their in-place version) from NLPModels:

You need to call jac_structure_residual! at least once before calling jac_op_residual!.

meta_nls = nls_meta(model)
