IloCplex.Status (CPLEX Java API Reference Manual)

java.lang.Object
- ilog.cplex.IloCplex.Status

Enclosing class:

IloCplex
```
public static class IloCplex.Status
extends java.lang.Object
```
Enumeration of possible solution status values, as returned by the method cplex.getStatus.
The status contains the information the IloCplex optimizer has gathered so far about a possible solution to the active model. User code typically refers to a solution status by specifying the full path, for example IloCplex.Status.Optimal.

Field Summary

Fields
Modifier and Type	Field and Description
`static IloCplex.Status`	`Bounded` The `Bounded` solution status reports that the `IloCplex` optimizer has determined that the model is not unbounded.
`static IloCplex.Status`	`Error` The `Error` solution status reports that an error has occurred.
`static IloCplex.Status`	`Feasible` The `Feasible` solution status reports that the `IloCplex` optimizer has found a feasible solution that can be queried with the method `getValue`.
`static IloCplex.Status`	`Infeasible` The `Infeasible` solution status reports that the `IloCplex` optimizer has determined that the model is infeasible.
`static IloCplex.Status`	`InfeasibleOrUnbounded` The `InfeasibleOrUnbounded` solution status reports that the `IloCplex` optimizer has determined that the model is infeasible or unbounded.
`static IloCplex.Status`	`Optimal` The `Optimal` solution status reports that the `IloCplex` optimizer has found an optimal solution that can be queried with the method `getValue`.
`static IloCplex.Status`	`Unbounded` The `Unbounded` solution status reports that the `IloCplex` optimizer has determined that the model is unbounded.
`static IloCplex.Status`	`Unknown` The `Unknown` solution status reports that the optimizer has not gathered any information about the active model.

- Field Detail
  - Error
```
public static final IloCplex.Status Error
```
    The Error solution status reports that an error has occurred.
  - Unknown
```
public static final IloCplex.Status Unknown
```
    The Unknown solution status reports that the optimizer has not gathered any information about the active model.
    This is usually the status before a solve method has been called, or after the model has been manipulated.
  - Feasible
```
public static final IloCplex.Status Feasible
```
    The Feasible solution status reports that the IloCplex optimizer has found a feasible solution that can be queried with the method getValue.
    Neither the optimality nor the nonoptimality of this solution has been proven.
  - Bounded
```
public static final IloCplex.Status Bounded
```
    The Bounded solution status reports that the IloCplex optimizer has determined that the model is not unbounded.
    This status does not imply that the model is feasible.
  - Optimal
```
public static final IloCplex.Status Optimal
```
    The Optimal solution status reports that the IloCplex optimizer has found an optimal solution that can be queried with the method getValue.
    The solution is proven to be optimal only within tolerances and achievable numeric accuracy.
  - Infeasible
```
public static final IloCplex.Status Infeasible
```
    The Infeasible solution status reports that the IloCplex optimizer has determined that the model is infeasible.
  - Unbounded
```
public static final IloCplex.Status Unbounded
```
    The Unbounded solution status reports that the IloCplex optimizer has determined that the model is unbounded.
    It has not, however, found the model to be feasible. Instead, the optimizer has proven that for any feasible solution, a better one could be constructed.
    
    In order to check whether the model is feasible, remove the objective function and re-optimize.
  - InfeasibleOrUnbounded
```
public static final IloCplex.Status InfeasibleOrUnbounded
```
    The InfeasibleOrUnbounded solution status reports that the IloCplex optimizer has determined that the model is infeasible or unbounded.
