Method Details

buildPhaseScope

protected ConstructionHeuristicPhaseScope<Solution_> buildPhaseScope(SolverScope<Solution_> solverScope,
 int phaseIndex)

Overrides:

buildPhaseScope in class DefaultConstructionHeuristicPhase<Solution_>

isNested

protected boolean isNested()

Description copied from class: AbstractPhase

Whether this phase is nested inside another phase. Nested phases, such as ruin and recreate, must not notify the solver of their starting; otherwise unimproved termination of local search would be reset every time the nested phase starts, effectively disabling this termination. Nested phases also do not collect step and phase metrics.

Overrides:

isNested in class AbstractPhase<Solution_>

Returns:

false for nested phases, true for every other phase

getPhaseTypeString

public String getPhaseTypeString()

Overrides:

getPhaseTypeString in class DefaultConstructionHeuristicPhase<Solution_>

doStep

protected void doStep(ConstructionHeuristicStepScope<Solution_> stepScope)

Overrides:

doStep in class DefaultConstructionHeuristicPhase<Solution_>

getMissingUpdatedElementsMap

public Map<Object,List<Object>> getMissingUpdatedElementsMap()
