  • Method Details

    • CpRandomSeed

      public static long CpRandomSeed()

    • zero

      public static long zero()
      NOLINT
      This method returns 0. It is useful when 0 can be cast either as
      a pointer or as an integer value and thus lead to an ambiguous
      function call.

    • One

      public static long One()
      This method returns 1

    • setAssignmentFromAssignment

      public static void setAssignmentFromAssignment(Assignment target_assignment, IntVar[] target_vars, Assignment source_assignment, IntVar[] source_vars)
      NOLINT
      Given a "source_assignment", clears the "target_assignment" and adds
      all IntVars in "target_vars", with the values of the variables set according
      to the corresponding values of "source_vars" in "source_assignment".
      source_vars and target_vars must have the same number of elements.
      The source and target assignments can belong to different Solvers.

    • areAllBound

      public static boolean areAllBound(IntVar[] vars)

    • areAllBooleans

      public static boolean areAllBooleans(IntVar[] vars)

    • areAllBoundTo

      public static boolean areAllBoundTo(IntVar[] vars, long value)
      Returns true if all variables are assigned to 'value'.

    • maxVarArray

      public static long maxVarArray(IntVar[] vars)

    • minVarArray

      public static long minVarArray(IntVar[] vars)

    • posIntDivUp

      public static long posIntDivUp(long e, long v)

    • posIntDivDown

      public static long posIntDivDown(long e, long v)

    • defaultRoutingModelParameters

      public static RoutingModelParameters defaultRoutingModelParameters()

    • defaultRoutingSearchParameters

      public static RoutingSearchParameters defaultRoutingSearchParameters()

    • findErrorInRoutingSearchParameters

      public static String findErrorInRoutingSearchParameters(RoutingSearchParameters search_parameters)
      Returns an empty std::string if the routing search parameters are valid, and
      a non-empty, human readable error description if they're not.

    • SolveModelWithSat

      public static boolean SolveModelWithSat(RoutingModel model, RoutingSearchParameters search_parameters, Assignment initial_solution, Assignment solution)
      Attempts to solve the model using the cp-sat solver. As of 5/2019, will
      solve the TSP corresponding to the model if it has a single vehicle.
      Therefore the resulting solution might not actually be feasible. Will return
      false if a solution could not be found.
