WebOct 1, 2006 · One obvious choice for the centroid is the graph-theoretic center (Harary, 1969), which is the node (or pair of nodes if not unique) that has the least eccentricity. A node's eccentricity is the length of its longest geodesic path to another node. We can then measure closeness as a node's geodesic distance from the center.
