getGraphCenter
public java.util.Set<V> getGraphCenter()
Compute the graph center. The center of a graph is the set of vertices of graph eccentricity equal to the graph radius.Note: The input graph must be undirected.
- Returns:
- the graph center
- Throws:
java.lang.IllegalArgumentException
- ifgraph
is not undirected
