Struct CrossoverOptions 

pub struct CrossoverOptions {
    pub enabled: bool,
    pub mult_tol: Number,
    pub primal_tol: Number,
    pub max_iter: u32,
}

Tuning for the crossover phase. Populated from the crossover* options by crate::application::IpoptApplication.

Fields

enabled: bool

Master switch (crossover). Default off.

mult_tol: Number

Multiplier magnitude above which a row is taken active in the §7 step-2 tolerance test (crossover_mult_tol).

primal_tol: Number

Primal distance to a bound below which a row is taken binding in the §7 step-2 tolerance test (crossover_primal_tol).

max_iter: u32

Outer-iteration budget for the §7 step-4 fallback (crossover_max_iter). 0 disables step 4 entirely, leaving crossover as the one-step refinement of step 3.
