Struct DualCertificateResiduals 

pub struct DualCertificateResiduals {
    pub curvature: f64,
    pub objective_gap: f64,
    pub recession_violation: f64,
}

Independently recomputed residuals of a DualCertificate.

The certificate is valid to tolerance eps when curvature <= eps, recession_violation <= eps, and objective_gap <= -eps (for a direction normalized to unit infinity norm).

Fields

curvature: f64

||Q v||_inf; zero when the ray carries no quadratic cost.

objective_gap: f64

q' v plus, when the problem has an L1Term, its recession slope sum_i costs[i] * |v_i|; strictly negative when the full objective descends along the ray.

recession_violation: f64

Largest violation of the constraint recession cone: |A_e v|, positive parts of A_i v, positive components where an upper bound is finite, negative components where a lower bound is finite.
