dominated_hypervolume function

Dominated Hypervolume calculation

Dominated Hypervolume calculation

dominated_hypervolume calculates the dominated hypervolume of the points in points.

dominated_hypervolume(points, ref) hypervolume_contribution(points, ref)

Arguments

  • points: Matrix containing the points one per column.
  • ref: Optional reference point. If not provided the maximum in each dimension is used.

Returns

For dominated_hypervolume the dominated hypervolume by the points in points with respect to the reference point ref. For hypervolume_contribution a vector giving the hypervolume soley dominated by that point.

Details

hypervolume_contribution calculates the hypervolume contribution of each point.

If no reference point ref is given, one is automatically calculated by determening the maximum in each coordinate.

Currently only one general algorithm is implemented due to Fonseca et.al. but work is underway to include others such as the Beume & Rudolph approach as well as the approach by Bradstreet et.al.

The 1D and 2D cases are handle seperately by efficient algorithms. Calculates the exact dominated hypervolume of the points given in x subject to the reference point ref.
