Enum Constant Details

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 Details

values

public static HxSolutionStatus[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static HxSolutionStatus valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null
