Struct DualCertificate 

pub struct DualCertificate {
    pub direction: Vec<f64>,
}

An unbounded-descent certificate of dual infeasibility, normalized to unit infinity norm.

The direction v proves the objective decreases without bound: Q v ~ 0 (no quadratic cost along the ray), q' v < 0 (the linear cost strictly decreases), and v is a recession direction of the constraints (A_e v ~ 0, A_i v <~ 0, non-positive where an upper bound is finite, non-negative where a lower bound is finite). Verify with check_dual_certificate.

Fields

direction: Vec<f64>

The unbounded descent direction in the decision space.
