Enum CpSolverStatus

  • All Implemented Interfaces:
    com.google.protobuf.Internal.EnumLite, com.google.protobuf.ProtocolMessageEnum, java.io.Serializable, java.lang.Comparable<CpSolverStatus>
    public enum CpSolverStatus
extends java.lang.Enum<CpSolverStatus>
implements com.google.protobuf.ProtocolMessageEnum
     The status returned by a solver trying to solve a CpModelProto.
    Protobuf enum operations_research.sat.CpSolverStatus

    • Enum Constant Detail

      • 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 feasiblity 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;

    • Method Detail

      • values

        public static CpSolverStatus[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows: 
        for (CpSolverStatus c : CpSolverStatus.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static CpSolverStatus valueOf​(java.lang.String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null

      • forNumber

        public static CpSolverStatus forNumber​(int value)
        Parameters:
        value - The numeric wire value of the corresponding enum entry.
