When running graph functions, the iteration number displayed in the Aster Management Console (AMC) is not same as the function’s iteration number. For example, when running the EigenvectorCentrality function, each EigenvectorCentrality iteration (EI) consumes 2 SQL-GR iterations (GI). For directed graphs, including the overhead, GI = 2*EI +1. For undirected graphs, GI = 2 * EI + 3.

For the PageRank function, the number of SQL-GR iterations equals the number of Pagerank iterations + 1.
