Method Details

setup

public void setup(EvolutionState state,
 Parameter base)

Description copied from class: Species

The default version of setup(...) loads requested pipelines and calls setup(...) on them and normalizes their probabilities. If your individual prototype might need to know special things about the species (like parameters stored in it), then when you override this setup method, you'll need to set those parameters BEFORE you call super.setup(...), because the setup(...) code in Species sets up the prototype.

Specified by:

setup in interface Prototype

Overrides:

setup in class DOVSSpecies

updateMostPromisingArea

public void updateMostPromisingArea(EvolutionState state)

Constructing a hyperbox, which defines the next search area.

Overrides:

updateMostPromisingArea in class DOVSSpecies

mostPromisingAreaSamples

public ArrayList<Individual> mostPromisingAreaSamples(EvolutionState state,
 int popSize)

Sample from the hyperbox to get new samples for evaluation.

Overrides:
