scale_reference_directions function

Scale Reference Points

A implementation of Das and Dennis's Reference Points Generation.

scale_reference_directions(ref_dirs, scaling)

Arguments

• ref_dirs, scaling: where 'ref_dirs' are the reference points generated and 'scaling' are the scale on which the points are distributed.

Returns

A matrix with rescaled reference points uniformly distributed.

Details

The implemented Reference Point Generation is based on the Das and Dennis's systematic approach that places points on a normalized hyper-plane which is equally inclined to all objective axes and has an intercept of one on each axis.
