public class SimplePafReasoner
extends AbstractPafReasoner
```
This class implements a naive algorithm for computing probabilities of extensions in probabilistic argumentation frameworks from [Li, Oren, Norman. Probabilistic Argumentation Frameworks. TAFA'2011]. It considers all subgraphs and computes therefore exact probabilities
