scale_reference_directions {rmoo}

Scale Reference Points

Description

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

Usage

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.

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.

Value

A matrix with rescaled reference points uniformly distributed.
