Enum MpccStage 

pub enum MpccStage {
    Exact,
    Continuation,
    Penalty,
    Branch,
}

The stages, in the order the driver tries them.

Variants

Exact

Two solves from the model’s own start, each a candidate: a relaxed path (G·H <= EXACT_STAGE_TAU, one warm step to the continuation’s last τ, then its exact finish), and the exact product G·H = 0 solved cold (G·H <= 0 where the equality would leave the model with more equalities than variables).

Continuation

G·H <= τ for τ down SCHOLTES_SCHEDULE, each stage warm-started from the last, then one G·H = 0 solve from the end of it (G·H <= 0 where the equality would leave the model with more equalities than variables).

Penalty

G·H = 0 through the ℓ₁ exact-penalty barrier.

Branch

A branch NLP: each pair with one side held at zero, the other kept non-negative — run from a reported point that is not B-stationary, along the branch its B-stationarity check found a descent on (check_b_stationarity). Not in STAGES.
