    • Enum Constant Summary

      Enum Constants 
      Enum Constant Description
      Feasible
      Solution is feasible but optimality was not proven.
      Inconsistent
      Solution and model are inconsistent.
      Infeasible
      Solution is infeasible (some constraints are violated).
      Optimal
      Solution is optimal (all objective bounds are reached).

      • Inconsistent

        public static final HxSolutionStatus Inconsistent
        Solution and model are inconsistent. The optimizer was able to prove that the model admits no feasible solution. Note that even a model without any constraint can be inconsistent, because some computations can yield undefined results. For instance, computing sqrt(x) with negative x yields an undefined value, which causes the solution to be invalid if it is used in an objective or a constraint (directly or indirectly).

      • Infeasible

        public static final HxSolutionStatus Infeasible
        Solution is infeasible (some constraints are violated).

      • Feasible

        public static final HxSolutionStatus Feasible
        Solution is feasible but optimality was not proven.

      • Optimal

        public static final HxSolutionStatus Optimal
        Solution is optimal (all objective bounds are reached).

    • Method Detail

      • values

        public static HxSolutionStatus[] 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 (HxSolutionStatus c : HxSolutionStatus.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static HxSolutionStatus 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
