In adana: Adaptive Nature-Inspired Algorithms for Hybrid Genetic Optimization

Linear Ranking Selection 2

Description

The Linear Ranking Selection-2 operator selects via probabilities obtained using ordered numbers according to their fitness values. Selection pressure is not applied in this algorithm (Scrucca, 2013).

Usage

sellrs2(fitvals, ns, ...)

Arguments

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

Value

The indices of randomly selected individuals are returned.
