- Method Detail
  - getPartition1DominatedSet
```
public Set<V> getPartition1DominatedSet()
```
    Gets the subset dominated by partition1. Where $D$ is the set of vertices in $G$ that are not matched in the maximum matching of $G$, this set contains members of the first partition and vertices from the second partition that neighbour them.
    
    Returns:
    
    The vertices in $D \cap V_1$ and their neighbours
  - getPartition2DominatedSet
```
public Set<V> getPartition2DominatedSet()
```
    Gets the subset dominated by partition2. Where $D$ is the set of vertices in $G$ that are not matched in the maximum matching of $G$, this set contains members of the second partition and vertices from the first partition that neighbour them.
    
    Returns:
    
    The vertices in $D \cap V_2$ and their neighbours
  - getPerfectMatchedSets
```
public List<Set<V>> getPerfectMatchedSets()
```
    Gets the remaining subset, or subsets in the fine decomposition. This set contains vertices that are matched in the maximum matching of the graph $G$. If the fine decomposition was used, this will be multiple sets, each a strongly-connected-component of the matched subset of $G$.
    
    Returns:
    
    List of Sets of vertices in the subsets
