pub fn probe(
tnlp: &Rc<RefCell<dyn TNLP>>,
options: &OptionsList,
) -> Result<SquareSystemPlan, SquareSystemDecline>Expand description
Decide whether the model the ladder was handed is in this stage’s class.
Costs one get_nlp_info, one get_bounds_info and — only on a model that
is square and equality-only — one starting point, one Jacobian structure
query and one ∇f evaluation.
