Method Details

buildBaseMoveSelector

protected MoveSelector<Solution_> buildBaseMoveSelector(HeuristicConfigPolicy<Solution_> configPolicy,
 SelectionCacheType minimumCacheType,
 boolean randomSelection)

Description copied from class: AbstractMoveSelectorFactory

Builds a base MoveSelector without any advanced capabilities (filtering, sorting, ...).

Specified by:

buildBaseMoveSelector in class AbstractMoveSelectorFactory<Solution_,ListSwapMoveSelectorConfig>

Parameters:

configPolicy - never null

minimumCacheType - never null, If caching is used (different from SelectionCacheType.JUST_IN_TIME), then it should be at least this SelectionCacheType because an ancestor already uses such caching and less would be pointless.

randomSelection - true is equivalent to SelectionOrder.RANDOM, false is equivalent to SelectionOrder.ORIGINAL

Returns:

never null

buildUnfoldedMoveSelectorConfig

protected MoveSelectorConfig<?> buildUnfoldedMoveSelectorConfig(HeuristicConfigPolicy<Solution_> configPolicy)

Description copied from class: AbstractMoveSelectorFactory

To provide unfolded MoveSelectorConfig, override this method in a subclass.

Overrides:

buildUnfoldedMoveSelectorConfig in class AbstractMoveSelectorFactory<Solution_,ListSwapMoveSelectorConfig>

Parameters:

configPolicy - never null

Returns:

null if no unfolding is needed

buildUnfoldedMoveSelectorConfig

protected MoveSelectorConfig<?> buildUnfoldedMoveSelectorConfig(List<ListVariableDescriptor<Solution_>> variableDescriptorList)
