Struct gurobi::QuadExpr

pub struct QuadExpr {
    // some fields omitted
}

Quadratic expression of variables

A quadratic expression consists of a linear expression and a set of variable-variable-coefficient triples to express the quadratic term.

Methods

impl QuadExpr

fn new() -> Self

fn add_term(self, coeff: f64, var: Var) -> Self

Add a linear term into the expression.

fn add_qterm(self, coeff: f64, row: Var, col: Var) -> Self

Add a quadratic term into the expression.

fn add_constant(self, constant: f64) -> Self

Add a constant into the expression.

fn get_value(&self, model: &Model) -> Result<f64>

Get actual value of the expression.
