Set niching distance to percentage of non-dominated range
Alias: none
Argument(s): REALLIST
Default: 0.01 for all objectives
The radial
nicher requires as input a vector of fractions with length equal to the number of objectives. The elements of the vector are interpreted as percentages of the non-dominated range for each objective defining a minimum distance to all other designs. All values should be in the range (0, 1). The minimum allowable distance between any two designs in the performance space is the Euclidian (simple square-root-sum-of-squares calculation) distance defined by these percentages. The distance
nicher has a similar input vector requirement, only the distance is the minimum distance in each dimension.
