All Implemented Interfaces:

```
public class SimplePreferredReasoner
extends AbstractExtensionReasoner
```
This reasoner for Dung theories performs inference on the preferred extensions. Computes the set of all preferred extensions, i.e., all maximal admissable sets. It does so by first computing all complete extensions and then check for set maximality.

```
public Extension getModel(DungTheory bbase)
```
    Description copied from interface: ModelProvider
    
    Returns a single (dedicated) model of the given belief base. If the implemented method allows for more than one dedicated model, the selection may be non-deterministic.
    
    Specified by:
    
    getModel in interface ModelProvider<Argument,DungTheory,Extension>
    
    Specified by:
    
    getModel in class AbstractExtensionReasoner
    
    Parameters:
    
    bbase - some belief base
    
    Returns:
    
    a selected model of the belief base.
