Function hypervolume_contribution_wfg 

pub fn hypervolume_contribution_wfg(
    front: &[Vec<f64>],
    reference: &[f64],
    idx: usize,
) -> OptimizeResult<f64>

Compute the hypervolume contribution of solution idx to the total hypervolume.

The contribution is defined as:

HVC(x_i) = HV(P) - HV(P \ {x_i})

where P is the full Pareto front.

Arguments

• front — Full Pareto front as &[Vec<f64>].
• reference — Reference point.
• idx — Index of the solution whose contribution to compute.

Errors

Returns an error if idx >= front.len() or dimensions mismatch.

Examples

use scirs2_optimize::multiobjective::hypervolume::hypervolume_contribution_wfg;
let front = vec![vec![0.0, 1.0], vec![0.5, 0.5], vec![1.0, 0.0]];
let contrib = hypervolume_contribution_wfg(&front, &[2.0, 2.0], 1).expect("valid input");
assert!(contrib >= 0.0);
