chc
Create new population using replacement
Specification
Alias: None
Arguments: 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 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.
