Takes a population of mu individuals and another set of lambda
offspring individuals and selects mu individuals out of the union set according
to the survival selection strategy stored in the control object.
replaceMuPlusLambda(control, population, offspring, fitness = NULL,
fitness.offspring = NULL)
replaceMuCommaLambda(control, population, offspring, fitness = NULL,
fitness.offspring = NULL, n.elite = base::max(ceiling(length(population *
0.1)), 1L))
Arguments
| control |
[ecr_control]
Control object. |
| population |
[list]
Current set of individuals. |
| offspring |
[list]
Another set of individuals. |
| fitness |
[matrix]
Matrix of fitness values for the individuals from population.
This is only optional in the case that each individual in population has
an attribute “fitness”. |
| fitness.offspring |
[matrix]
Matrix of fitness values for the individuals from offspring.
This is only optional in the case that each individual in offspring has
an attribute “fitness”. |
| n.elite |
[integer(1)]
Number of fittest individuals of the current generation that shall be copied to the
next generation without changing. Keep in mind, that the algorithm
does not care about this option if the survival.strategy is set to 'plus'.
Default is 0. |
Value
[list] List with selected population and corresponding fitness matrix.
