Struct RestoOptions 

pub struct RestoOptions {
    pub bound_mult_reset_threshold: Number,
    pub constr_mult_reset_threshold: Number,
    pub resto_penalty_parameter: Number,
    pub resto_proximity_weight: Number,
    pub required_infeasibility_reduction: Number,
    pub evaluate_orig_obj_at_resto_trial: bool,
    pub expect_infeasible_problem: bool,
    pub start_with_resto: bool,
}

Restoration-phase knobs carried on the outer builder and copied into the RestoAlgorithmBuilder when the restoration factory is minted (pounce-restoration). The restoration builder is constructed with defaults by each frontend and never options-configured, so these were registered but never read (#191). Defaults mirror upstream’s restoration RegisterOptions.

Fields

bound_mult_reset_threshold: Number

bound_mult_reset_threshold — reset bound multipliers to 1 after restoration if the largest exceeds this.

constr_mult_reset_threshold: Number

constr_mult_reset_threshold — ignore the least-square constraint multiplier estimate after restoration if its norm exceeds this (0 keeps the estimate).

resto_penalty_parameter: Number

resto_penalty_parameter — penalty on the slack 1-norm in the restoration objective (rho).

resto_proximity_weight: Number

resto_proximity_weight — proximity-term weight (eta_factor; η = eta_factor · sqrt(μ)).

required_infeasibility_reduction: Number

required_infeasibility_reduction — the restoration sub-solve keeps iterating until the original NLP’s infeasibility has been reduced to at most this fraction of its value at restoration entry (κ_resto in IpRestoConvCheck.cpp:58). 0 disables the guard, i.e. restoration runs until the sub-NLP itself converges.

evaluate_orig_obj_at_resto_trial: bool

evaluate_orig_obj_at_resto_trial — evaluate the original objective at every restoration trial point, so an iterate the restoration problem likes but the original cannot evaluate is rejected there rather than after the phase exits. Upstream default yes. RestoAlgorithmBuilder has consumed this since it landed; only the read site was missing (gh#483, #191 round 2).

expect_infeasible_problem: bool

expect_infeasible_problem — enter restoration sooner and demand more infeasibility reduction before leaving it. Upstream default no. Same story: consumed, never read.

start_with_resto: bool

start_with_resto — switch to restoration in the first iteration. Upstream default no. Same story.
