Trait good_lp::solvers::SolutionWithDual[−][src]

pub trait SolutionWithDual<'a> {
    type Dual: DualValues;
    fn compute_dual(&'a mut self) -> Self::Dual;
}

The dual value measures the increase in the objective function’s value per unit increase in the variable’s value. The dual value for a constraint is nonzero only when the constraint is equal to its bound. Also known as the shadow price. This trait handles the retrieval of dual values from a solver.

Associated Types

type Dual: DualValues[src]

Type of the object containing the dual values.

Required methods

fn compute_dual(&'a mut self) -> Self::Dual[src]

Get the dual values for a problem. If a solver requires running additional computations or allocating additional memory to get the dual values, this is performed when running this method.
