| Abstract: | In this paper, we study the iterative method for PageRank computation. Based on the inner-outer iterative method which was proposed by Gleich et al., we present a generalized two-stage iterative method with three parameters which cover inner-outer iterative method and power method. Under some suitable conditions, the convergence results are given. Based on the formula of the contraction factor of the method, we discuss possible choices of the iteration parameters, which could be practically useful for accelerating the convergence rate of the inner-outer iteration method. |
