- - net.sf.tweety.arg.rankings.reasoner.DiscussionBasedRankingReasoner

All Implemented Interfaces:

ModelProvider<Argument,DungTheory,LatticeArgumentRanking>, PostulateEvaluatable<Argument>
```
public class DiscussionBasedRankingReasoner
extends AbstractRankingReasoner<LatticeArgumentRanking>
```
This class implements the "Discussion-based" argument semantics approach as proposed by [Amgoud, Ben-Naim. Ranking-based semantics for argumentation frameworks. 2013]. It compares arguments by counting the number of paths ending to to them. If some arguments are equivalent wrt. to their number of direct attackers, the size of paths is increased recursively until a difference is found.

  - getModels
```
public java.util.Collection<LatticeArgumentRanking> getModels(DungTheory bbase)
```
    Description copied from interface: ModelProvider
    
    Returns a characterizing model of the given belief base
    
    Parameters:
    
    bbase - some belief base
    
    Returns:
    
    the (selected) models of the belief base
  - getModel
```
public LatticeArgumentRanking getModel(DungTheory kb)
```
    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.
    
    Parameters:
    
    kb - some belief base
    
    Returns:
    
    a selected model of the belief base.
  - getNumberOfPathsOfLength
```
public int getNumberOfPathsOfLength(DungTheory base,
                                    Argument a,
                                    int i)
```
    Returns the number of linear discussions of the given length in the given DungTheory for the given argument.
    
    Parameters:
    
    base - the abstract argumentation framework
    
    a - an argument
    
    i - length of linear discussions
    
    Returns:
    
    the number of linear discussions of the given length
