Provides the functions of the Genetic Algorithm Toolbox for 'MATLAB' developed at the University of Sheffield (Chipperfield et al. 1994, < https://github.com/UoS-CODeM/GA-Toolbox>), rewritten in R. It includes operators for creating binary, integer and real-valued populations, rank-based and linear fitness assignment, roulette wheel and stochastic universal sampling selection, single-point, multi-point, shuffle and reduced surrogate crossover, discrete, intermediate and line recombination, discrete and breeder genetic algorithm mutation, reinsertion of offspring, and migration between subpopulations.
