How do you compute page rank for billion of pages that have cyclic links? Is that not the problem right after the initial idea?
That is not at all a problem. Links dampen their effect and you run it until convergence - read the paper. It's no different than summing an infinite convergent series, $\sum_{i=0}^n a^{-n}$.
Also, WTF, it seems impossible to find a PDF of the original paper still on the web without a paywall.
