select_parents: select_parents

In jtkwar/GA: Genetic Algorithm for Variable Selection in Regression Problems

Description

This function returns pairs of parents for breeding

Usage

select_parents(fitness_values, mechanism, random = random, P, c)

Arguments

fitness_values	(vector P): fitness_value of each of the candidate of the current generation
P	(int): number of candidates per generation
mechanism:	user defined rank-based selection mechanism, must be one of c("replace_all","tournament", "partial_replace")
random:	A boolean value(T/F), "T" if choosing 1 parent selected proportional to fitness + 1 parent random selected and "F" if 2 parents selected proportional to to fitness
generation	gap: proportion of the generation to be replaced by offspring output:

Value

parents (matrix P x 2): each row is a pair of indices of parents

candidate(P x c): Each row is a candidate model for breeding
