Struct InitOptions 

pub struct InitOptions {
    pub bound_push: Number,
    pub bound_frac: Number,
    pub slack_bound_push: Number,
    pub slack_bound_frac: Number,
    pub constr_mult_init_max: Number,
    pub bound_mult_init_val: Number,
    pub bound_mult_init_method: String,
    pub least_square_init_primal: bool,
}

Knobs read off OptionsList and baked into DefaultIterateInitializer. Defaults mirror IpDefaultIterateInitializer.cpp:RegisterOptions. The Mehrotra cascade in application.rs overrides bound_push, bound_frac, and bound_mult_init_val to upstream’s more-aggressive values (10, 0.2, 1.0).

Fields

bound_push: Number

bound_frac: Number

slack_bound_push: Number

slack_bound_frac: Number

constr_mult_init_max: Number

bound_mult_init_val: Number

bound_mult_init_method: String

bound_mult_init_method: "constant" (default) or "mu-based" (matches upstream’s IpDefaultIterateInitializer.cpp).

least_square_init_primal: bool

least_square_init_primal — replace the user’s starting x with the min-norm primal that satisfies the linearized constraints. Used by the Mehrotra cascade in application.rs to drop iter-0 primal infeasibility on LP-shaped problems. Mirrors upstream IpDefaultIterateInitializer.cpp:200-222.

Trait Implementations

impl Clone for InitOptions

fn clone(&self) -> InitOptions

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for InitOptions

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for InitOptions

fn default() -> Self

Returns the “default value” for a type.
