selescale: Exponent Scaling

Description

The Exponent Scaling operator is the selection operator in which the fitness values are scaled by the simulated annealing method.

Usage

selescale(fitvals, ns, selb, ...)

Arguments

fitvals

Vector of fitness values belonging to individuals

ns

Number of individuals to be selected

selb

Exponent coefficent, (selb >= 0.0)

…

Further arguments passed to or from other methods.

Value

The indices of randomly selected individuals are returned.
