Protobuf enum operations_research.sat.CpSolverStatus

  • Enum Constant Details

    • UNKNOWN

      public static final CpSolverStatus UNKNOWN
       The status of the model is still unknown. A search limit has been reached
 before any of the statuses below could be determined.
      UNKNOWN = 0;

    • MODEL_INVALID

      public static final CpSolverStatus MODEL_INVALID
       The given CpModelProto didn't pass the validation step. You can get a
 detailed error by calling ValidateCpModel(model_proto).
      MODEL_INVALID = 1;

    • FEASIBLE

      public static final CpSolverStatus FEASIBLE
       A feasible solution has been found. But the search was stopped before we
 could prove optimality or before we enumerated all solutions of a
 feasibility problem (if asked).
      FEASIBLE = 2;

    • INFEASIBLE

      public static final CpSolverStatus INFEASIBLE
       The problem has been proven infeasible.
      INFEASIBLE = 3;

    • OPTIMAL

      public static final CpSolverStatus OPTIMAL
       An optimal feasible solution has been found.

 More generally, this status represent a success. So we also return OPTIMAL
 if we find a solution for a pure feasibility problem or if a gap limit has
 been specified and we return a solution within this limit. In the case
 where we need to return all the feasible solution, this status will only be
 returned if we enumerated all of them; If we stopped before, we will return
 FEASIBLE.
      OPTIMAL = 4;

    • UNRECOGNIZED

      public static final CpSolverStatus UNRECOGNIZED

  • Field Details

    • UNKNOWN_VALUE

      public static final int UNKNOWN_VALUE
       The status of the model is still unknown. A search limit has been reached
 before any of the statuses below could be determined.
      UNKNOWN = 0;

    • MODEL_INVALID_VALUE

      public static final int MODEL_INVALID_VALUE

       The problem has been proven infeasible.
