Computes the paths from each category node to the root . Computing n paths will take some time . Thus efficient computing is based on the assumption that all subpaths in the shortest path to the root are also shortest paths for the corresponding nodes . Starting with the leaf nodes gives the longest initial paths with ...

public Map < Integer , Integer > getDegreeDistribution ( ) { if ( degreeDistribution == null ) { logger . debug ( "Calling setGraphParameters" ) ; setGraphParameters ( ) ; } return degreeDistribution ; }
Computes the degree distribution . The degree of a node is the number of edges that it is connected with . The graph is treated as an undirected graph . Computing graph parameters requires touching all node pairs . Therefore if one is called the others are computed as well and stored for later retrieval .
