Create new population randomly

Specification

Alias: none

Argument(s): INTEGER

Description

The replacement_type controls how current populations and newly generated individuals are combined to create a new population. Each of the replacement_type selections accepts an integer value, which is referred as the replacement_size:

The random setting creates a new population using:

  • replacement_size randomly selected individuals from the current population, and
  • population_size - replacement_size individuals randomly selected from among the newly generated individuals (the number of which is optionally specified using new_solutions_generated) that are created for each generation (using the selection, crossover, and mutation procedures).
