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).
