Nonlinear Ranking Selection

Description

The Nonlinear Ranking Selection is a nonlinear selection method that applies higher selection pressure than the Linear Ranking Selection (Pholheim, 1995).

Usage

selnlrs(fitvals, ns, selns, ...)

Arguments

fitvals	Vector of fitness values belonging to individuals
ns	Number of individuals to be selected
selns	Number of Selection pressure
...	Further arguments passed to or from other methods.

Value

The indices of randomly selected individuals are returned.
