Method Detail

buildBaseMoveSelector

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

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

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

buildMoveSelector

public MoveSelector<Solution_> buildMoveSelector(HeuristicConfigPolicy<Solution_> configPolicy,
                                                 SelectionCacheType minimumCacheType,
                                                 SelectionOrder inheritedSelectionOrder)

Builds MoveSelector from the MoveSelectorConfig and provided parameters.

Specified by:

buildMoveSelector in interface MoveSelectorFactory<Solution_>

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.

inheritedSelectionOrder - never null

Returns:

never null

buildUnfoldedMoveSelectorConfig

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

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

Parameters:

configPolicy - never null

Returns:

null if no unfolding is needed

determineBaseRandomSelection

protected boolean determineBaseRandomSelection(SelectionCacheType resolvedCacheType,
                                               SelectionOrder resolvedSelectionOrder)

isBaseInherentlyCached

protected boolean isBaseInherentlyCached()

validateSorting

protected void validateSorting(SelectionOrder resolvedSelectionOrder)

applySorting

protected MoveSelector<Solution_> applySorting(SelectionCacheType resolvedCacheType,
                                               SelectionOrder resolvedSelectionOrder,
                                               MoveSelector<Solution_> moveSelector)
