Re: [mpgraph-developers] Problem with increasing the no of iterations in pagerank

[Bryan T. <br...@sy...>]

Have you tried to modify pagerank.cu?

If the problem that it does not do more iterations or that the results do
not converge if you request more iterations?

The page rank implementation uses a delta rule. It terminates if the
frontier becomes empty regardless of the number of iterations specified.

Thanks,
Bryan
