Method Detail

chooseNextLocation

protected boolean chooseNextLocation()

Description copied from class: BaseGridSearch

Choose the next location we will search. This method is responsible for setting the currentLocation variable.

Overrides:

chooseNextLocation in class RandomGridSearch

Returns:

false if the search is to abort.

setBudget

public void setBudget(double budget)

Description copied from class: WeightLearningApplication

Set a budget (give as a proportion of the max budget). Child implementations should make sure to override this and call up the super chain.

Overrides:

setBudget in class RandomGridSearch
