Required Methods§

Source

fn set_initial_iterates( &mut self, data: &IpoptDataHandle, cq: &IpoptCqHandle, nlp: &Rc<RefCell<dyn IpoptNlp>>, aug_solver: &mut dyn AugSystemSolver, ) -> bool

Populate IpoptData::curr with an initial iterate. Mirrors IterateInitializer::SetInitialIterates. The implementation can use aug_solver for least-square multiplier estimates; callers that don’t need that may pass any solver — concrete initializers consult it only if their option settings require it.

Provided Methods§

Source

fn least_square_report(&self) -> Option<LeastSquareInitReport>

Diagnostics from the safeguarded least_square_init_primal step (gh#605): initial/final nonlinear violation, accepted step norm, rejected-trial count, termination reason. None for initializers that do not run that step, or when it was not attempted on this solve.
