Struct ObjectiveBounds 

pub struct ObjectiveBounds {
    pub sense: String,
    pub primal: Option<f64>,
    pub dual: Option<f64>,
}

Fields

sense: String

minimize or maximize: the dual bound is a lower bound when minimizing and an upper bound when maximizing.

primal: Option<f64>

Objective of the best feasible point, if one was found.

dual: Option<f64>

Proven bound on the optimal objective, if the solver proved one.

Implementations

impl ObjectiveBounds

pub fn ordered(&self) -> bool

Whether the bounds are in order: when both exist, the dual bound lies below the primal one when minimizing and above it when maximizing, within BOUND_TOLERANCE. A dual bound beyond the objective of a feasible point contradicts it: one of the two is wrong.
