Existing options keys

[ocots]

Hi @tmigot @amontoison @abelsiqueira and others!

I am working on control-toolbox and I would handle options for the modelers and solvers quite nicely for the user. To do this, I need a way to get all the existing options keys we can pass when solving with Ipopt.

solver = NLPModelsIpopt.IpoptSolver(nlp)
NLPModelsIpopt.solve!(solver, nlp; options...)

Is there a way to get the possible keys? I am aware of this page but the list is long: Ipopt options.

Thanks!

Same answer as JuliaSmoothOptimizers/NLPModelsKnitro.jl#138
The docstring should document this

NLPModelsIpopt.jl/src/NLPModelsIpopt.jl

Line 189 in ad1cf0f

function ipopt(nlp::AbstractNLPModel; kwargs...)

up to two things:

• zL and zU should actually be zL0 and zU0
• There is also the callback keyword
