Hypervolume calculation methods

Variants

WFG

Walking Fish Group algorithm.

WFG computes the exact hypervolume, so this crate evaluates it with the same exact slicing recursion as HypervolumeMethod::HSO. The two therefore return bit-identical results; they differ only in the internal traversal order a dedicated implementation would use, never in the value.

Quick

Quick hypervolume (QHV).

Also an exact algorithm, evaluated here through the same exact recursion. Selecting it is honest — the returned number is the true hypervolume — it simply does not use QHV’s own pivot decomposition.

HSO

Hypervolume by slicing objectives (the recursion implemented here).

MonteCarlo

Monte Carlo estimation by uniform sampling of the reference box.

This is a genuine estimator (not a fallback to the exact routine): it draws HypervolumeCalculator::monte_carlo_samples uniform points from the box spanned by the front’s ideal corner and the reference point and returns box_volume * dominated_fraction. Use it only when an approximation is acceptable; it is seeded, so repeated calls on the same input agree.
