Abstract:

In order to solve the PageRank problem, a new algorithm Hessenberg-Chebyshev is proposed by combining Hessenberg-type algorithm with Chebyshev acceleration technology. This algorithm improves the Hessenberg-type algorithm based on the acceleration technique of Chebyshev polynomial. The implementation and convergence analysis of the new algorithm are discussed in detail, and the effectiveness of the algorithm is verified by numerical experiments.

Key words: Hessenberg process, Chebyshev polynomials, iterative method, convergence, PageRank
