    • AbstractPhaseScope

      protected AbstractPhaseScope(SolverScope<Solution_> solverScope, int phaseIndex)
      As defined by #AbstractPhaseScope(SolverScope, int, boolean) with the phaseSendingBestSolutionEvents parameter set to true.

    • AbstractPhaseScope

      protected AbstractPhaseScope(SolverScope<Solution_> solverScope, int phaseIndex, boolean phaseSendingBestSolutionEvents)
      Parameters:
      solverScope - never null
      phaseIndex - the index of the phase, >= 0
      phaseSendingBestSolutionEvents - set to false if the phase only sends one best solution event at the end, or none at all; this is typical for construction heuristics, whose result only matters when it reached its natural end.
