Implementations

impl ProbingMuOracle

pub fn new() -> Self

pub fn probing_mu(mu_curr: Number, mu_aff: Number, sigma_max: Number) -> Number

Pure-arithmetic probing formula from IpProbingMuOracle.cpp:117.

pub fn calculate_mu_with_affine_step( &mut self, data: &IpoptDataHandle, cq: &IpoptCqHandle, nlp: &Rc<RefCell<dyn IpoptNlp>>, pd_search_dir: &mut PdSearchDirCalc, tau: Number, ) -> Option<Number>

Drive the affine (predictor) step through pd_search_dir, snapshot μ_aff from the projected complementarity, then return the probed μ_new ∈ [mu_min, mu_max]. Returns None if the affine linear solve fails (caller falls back to LOQO).

tau is the fraction-to-the-boundary parameter (typically 1.0 for the affine probe per upstream’s IpProbingMuOracle.cpp:107).

Trait Implementations

impl Default for ProbingMuOracle

fn default() -> Self

Returns the “default value” for a type.

impl MuOracle for ProbingMuOracle

fn calculate_mu(&mut self) -> Option<Number>

Probe the next mu given the current iterate state. Phase 10 fills in the actual signatures; trait surface here keeps the option matrix matchable in AlgBuilder.
