info: https://github.com/JuliaSmoothOptimizers/NLPModelsIpopt.jl/blob/main/src/NLPModelsIpopt.jl#L119
options of ipopt: https://coin-or.github.io/Ipopt/OPTIONS.html
callback: https://github.com/jump-dev/Ipopt.jl#solver-specific-callback
solution field 'stats': https://juliasmoothoptimizers.github.io/SolverCore.jl/stable/reference/#SolverCore.GenericExecutionStats

We typically use the non-default options:

• mu_strategy="adaptive" appears better than the default option (monotone) for OCP problems
• sb="yes" to remove the ipopt header at the start

Informations of IPOPT

• What is the primal_inf in IPOPT ?
• What is exactly the dual_inf (dual feasibility) in IPOPT ?
