pub struct MultiObjective(/* private fields */);Expand description
Represents multiple real-valued objectives and can be used to represent an objective vector in multi-objective optimization.
This objective type is used for MultiObjectiveProblems.
§Restrictions
This is a wrapper around Vec<f64>, which can’t take NaN values,
and therefore can implement Eq.
For details, see IllegalObjective.
The PartialOrd implementation returns the Pareto ordering.
As the Pareto ordering leaves some vectors as incomparable, Ord is not implemented.

Source§fn partial_cmp(&self, other: &Self) -> Option<Ordering>
fn partial_cmp(&self, other: &Self) -> Option<Ordering>
Orders two objective value vectors using Pareto-domination.
Note that Ordering::Less means that self dominates other:
use std::cmp::Ordering;
use mahf::MultiObjective;
let a = MultiObjective::try_from(vec![0., 0.]).unwrap();
let b = MultiObjective::try_from(vec![1., 1.]).unwrap();
// `a` dominates `b` (minimization).
