Method Detail

getPartition1DominatedSet

public java.util.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 java.util.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 java.util.List<java.util.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
