Adding cardinality metric #87

Closed ffelten closed 9 months ago

ffelten commented 9 months ago

Some metrics can be very good for a small amount of points in the PF, e.g. HV, EUM, Sparsity.

I think this simple indicator already helps in mitigating such scenarios in problems with >3objs, where we cannot plot the front.

It also has the advantage of not requiring more ref points (contrary to spread).
