Description

Overwrites the new niche selecting from the best chromosomes. This method is called in the progeny method. For more information see Niche. for complete description.

Usage

## S3 method for class 'Niche'
offspring(ni, ...)

Details

The basic idea to generate a progeny is a selection biased toward the best chromosomes (see Goldberg). We implented this idea as a weighted probability (*scaling()).

offspring is part of progeny method.

For related details For more information see Niche.

Value

Returns the selected chromosomes.

Examples

   cr <- Chromosome(genes=newCollection(Gene(shape1=1, shape2=100),5))
   cr
   ni <- Niche(chromosomes = newRandomCollection(cr, 10))
   ni
   ni$fitness <- 1:10/10 # tricky fitness, only for showing purposes
   scaling(ni)
   offspring(ni)
