selDomHV: Dominated Hypervolume selector.

In ecr: Evolutionary Computation in R

Dominated Hypervolume selector.

Description

Performs non-dominated sorting and drops the individual from the last front with minimal hypervolume contribution. This selector is the basis of the S-Metric Selection Evolutionary Multi-Objective Algorithm, termed SMS-EMOA (see smsemoa).

Usage

selDomHV(fitness, n.select, ref.point)

Arguments

fitness	[matrix] Matrix of fitness values (each column contains the fitness value(s) of one individual).
n.select	[integer(1)] Number of elements to select.
ref.point	[numeric] Reference point for hypervolume computation.

Value

[integer] Vector of survivor indizes.

Note

Note that the current implementation expects n.select = ncol(fitness) - 1 and the selection process quits with an error message if n.select is greater than 1.
