class pymoode.performance.SpacingIndicator(metric='cityblock', pf=None, zero_to_one=False, ideal=None, nadir=None)

Spacing indicator The smaller the value this indicator assumes, the most uniform is the distribution of elements on the pareto front.

Parameters:

metricstr, optional

Distance metric parsed to scipy.spatial.distance.pdist, by default “cityblock”

pf2d array, optional

Pareto front, by default None

zero_to_onebool, optional

Whether or not the objective values should be normalized in calculations, by default False

ideal1d array, optional

Ideal point, by default None

nadir1d array, optional

Nadir point, by default None

Methods

__call__(F, *args, **kwargs)	Call self as a function.
do(F, *args, **kwargs)	Obtain the spacing indicator given a Pareto front
