An efficient elimination strategy for solving PageRank problems
In Web link structures, similar link distributions often occur, especially for pages from same hosts. For PageRank problems, similar in-link distributions of pages result in similar row patterns of the transition matrix. ...
A hybridized iterative algorithm of the BiCORSTAB and GPBiCOR methods for solving non-Hermitian linear systems
In this study, we derive a new iterative algorithm (including its preconditioned version) which is a hybridized variant of the biconjugate A-orthogonal residual stabilized (BiCORSTAB) method and the generalized product-type ...
Block-accelerated aggregation multigrid for Markov chains with application to PageRank problems
Recently, the adaptive algebraic aggregation multigrid method has been proposed for computing stationary distributions of Markov chains. This method updates aggregates on every iterative cycle to keep high accuracies of ...
Restarted Hessenberg method for solving shifted nonsymmetric linear systems
It is known that the restarted full orthogonalization method (FOM) outperforms the restarted generalized minimum residual (GMRES) method in several circumstances for solving shifted linear systems when the shifts are handled ...
