Struct WarmStartOptions 

pub struct WarmStartOptions {
    pub bound_push: Number,
    pub bound_frac: Number,
    pub slack_bound_push: Number,
    pub slack_bound_frac: Number,
    pub mult_bound_push: Number,
    pub mult_init_max: Number,

    pub constr_mult_init_max: Number,
    pub recentering: WarmStartRecentering,
}

Knobs read off OptionsList and baked into WarmStartIterateInitializer. Defaults mirror IpWarmStartIterateInitializer.cpp:RegisterOptions.

Wired today: every knob above plus the gh#606 recentering pair. warm_start_entire_iterate / warm_start_same_structure are deliberately not here — they name the GetWarmStartIterate TNLP surface pounce does not expose, and are refused by crate::unimplemented_options rather than parsed into a field nothing reads (gh#606).

Fields

bound_push: Number

bound_frac: Number

slack_bound_push: Number

slack_bound_frac: Number

mult_bound_push: Number

mult_init_max: Number

target_mu: Number

bound_mult_init_val: Number

The value a NaN-seeded bound multiplier takes: NaN in a user-supplied z/v seed means “unseeded, use the default”. Threaded from builder.init.bound_mult_init_val at build time so the Mehrotra override and any user setting stay the single source of truth.

constr_mult_init_max: Number

constr_mult_init_max, threaded from the init options at build time (gh#606). The warm path’s reconstruction of an unseeded equality-multiplier block runs the cold path’s least-squares solve, so it is capped by the cold path’s cap — not by warm_start_mult_init_max, which caps multipliers a caller actually supplied and is three orders looser (1e6 vs 1e3). Measured: on redundant_rows, whose duplicated equality rows make the least-squares system singular, the looser cap let an arbitrary estimate through and cost 7 -> 25 iterations.

recentering: WarmStartRecentering

warm_start_recentering (gh#606). Whether the initializer measures the supplied point and adapts μ / the multiplier fills to it, or keeps the pre-gh#606 universal constants.
