摘要 PageRank算法已经成为网络搜索中的核心技术.首先基于内外迭代法,运用预处理的思想,提出GMRES-Inout方法,即重启的GMRES方法修正的内外迭代法;然后,详细介绍该方法的具体过程及收敛性分析;最后,通过数值实验说明该方法的有效性. The PageRank algorithm for determining the importance of Web pages has become a central technique in Web search. Based on the inout method, a GMRES- Inout algorithm which modifying the inner-outer method preconditioned with the restarted GMRES algorithm is proposed. Description and convergence analysis of the proposed algorithm are given. Numerical results are reported to demonstrate the efficiency of the proposed algorithm.
