Create new population using replacement
Alias: none
Argument(s): INTEGER
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 chc
setting creates a new population using (a) the replacement_size
best individuals from the combination of the current population and the newly generated individuals, and (b) population_size
- replacement_size
individuals randomly selected from among the remaining individuals in this combined pool. The chc
setting is the preferred selection for many engineering problems.
