LinkRankMatrix

As of Version 10, all the functionality of the GraphUtilities package is built into the Wolfram System. »

LinkRankMatrix[g]

returns the link rank of the graph g, in the form of a sparse matrix. The link rank of an edge u->v is defined as the PageRanks of u, divided by the out-degree of u.

Details and Options

  • LinkRankMatrix functionality is now available in the built-in Wolfram Language function LinkRankCentrality.
  • To use LinkRankMatrix, you first need to load the Graph Utilities Package using Needs["GraphUtilities`"].
  • The following options can be given:
  • ToleranceAutomatictolerance used for convergence check
    TeleportProbability0.15probability of visiting random nodes
    RemoveSinksTruewhether to remove sinks by linking them with every node
  • The link rank of a link from vertex i to vertex j is defined as page rank of i, as given by PageRanks[g], divided by the out-degree of i.
  • The link rank reflects the probability that a random surfer follows that link.
  • LinkRankMatrix has the same options as PageRanks.
