inlinevirtual

The function that performs the selection.

Parameters

currentPopulation	The input population before the selection. For convenience, it will be sorted by fitness from lowest to highest.
populationMaxSize	The expected population size after the selection. When implementing a custom Perform method, you should make sure that the returned population size is equal to this value, if possible.

Returns

The new population after the selection. You can modify the currentPopulation or return a new collection.
