Enum Stop 

pub enum Stop {
    Infeasible,
    NoChange {
        rejected: Option<Rejection>,
    },
    Undecided,
    Flat {
        independent: usize,
        constraints: usize,
    },
    Damped {
        rejected: Option<Rejection>,
    },
    Budget,
}

Why minimize stopped where it did.

Variants

Infeasible

The residuals cannot be evaluated at the start.

NoChange

The next step changes no variable at all — after the steps before it were turned down, the last one for rejected.

Fields

rejected: Option<Rejection>

Undecided

Neither the sum’s change nor the violation’s can be told from their width, and the step no longer shrinks: as near the minimum as can be told.

Flat

The linearized model expects the next step to lower neither the sum nor the violation definitely — with independent of the constraints rows telling it something new.

Fields

independent: usize

constraints: usize

Damped

No step, however damped, is taken; the last one tried turned down for rejected.

Fields

rejected: Option<Rejection>

Budget

Options::max_iterations steps were taken.
