EmbryonicSelection: EmbryonicSelection

In dGAselID: Genetic Algorithm with Incomplete Dominance for Feature Selection

Description

Function for deleting individuals with a fitness below a specified threshold.

Usage

EmbryonicSelection(population, results, embryonicSelection)

Arguments

population	Population of individuals with diploid genotypes.
results	Results returned by EvaluationFunction().
embryonicSelection	Threshold value. The default value is NA.
