An ES works on a population of real valued solutions
|
|
by repeated use of evolutionary operators like reproduction,
|
|
recombination and mutation.
|
|
λ offspring individuals are generated from μ parents
|
|
by recombination and mutation (with μ < λ).
|
|
<br>
|
|
After evaluating the fitness of the λ
|
|
offspring individuals, the comma-strategy selects the μ individuals
|
|
with the best fitness as parent population for the next generation.
|
|
On the other hand, a plus-strategy selects the best μ individuals
|
|
from the aggregation of parents and offspring individuals, so in this
|
|
case the best individual is guaranteed to survive.
|
|
In general, however, the comma-strategy is more robust and can easier
|
|
escape from local optima, which is why it is usually the standard selection.
