Struct QpProblem 

pub struct QpProblem {
    pub quadratic: FactorQuad,
    pub linear: Vec<f64>,
    pub l1: Option<L1Term>,
    pub equalities: LinearConstraints,
    pub inequalities: LinearConstraints,
    pub lower_bounds: Vec<f64>,
    pub upper_bounds: Vec<f64>,
}

Standard-form convex QP accepted by Ledge.

The objective is 0.5 * x' Q x + linear' x plus an optional piecewise-linear term sum_i costs[i] * |x[i] - anchor[i]| (L1Term), with equality, upper-inequality, and box constraints.

Fields

quadratic: FactorQuad

Structured positive-semidefinite quadratic.

linear: Vec<f64>

Linear objective coefficient.

l1: Option<L1Term>

Optional proportional-cost term sum_i costs[i] * |x[i] - anchor[i]|.

equalities: LinearConstraints

Constraints A_eq * x = b_eq.

inequalities: LinearConstraints

Constraints A_ineq * x <= b_ineq.

lower_bounds: Vec<f64>

Variable lower bounds; -inf means unbounded.

Serialized as Option<f64> entries (null in JSON) for unbounded sides, because JSON cannot represent infinities — see serde_support.

upper_bounds: Vec<f64>

Variable upper bounds; +inf means unbounded.

Serialized as Option<f64> entries (null in JSON) for unbounded sides, because JSON cannot represent infinities — see serde_support.

Validates dimensions, finite coefficients, and bound consistency.

Errors

Returns a ProblemError when the problem is malformed.

pub fn objective(&self, x: &[f64]) -> f64

Evaluates the objective at x, including the L1 term when present.
