Alternating Anderson-Richardson method: An efficient alternative to preconditioned Krylov methods for large, sparse linear systems
Phanish Suryanarayana, Phanisri P. Pratapa, John E. Pask
We present the Alternating Anderson-Richardson (AAR) method: an efficient and scalable alternative to preconditioned Krylov solvers for the solution of large, sparse linear systems…

Convergence analysis of a locally accelerated preconditioned steepest descent method for Hermitian-definite generalized eigenvalue problems
Yunfeng Cai, Zhaojun Bai, John E. Pask +1
By extending the classical analysis techniques due to Samokish, Faddeev and Faddeeva, and Longsine and McCormick among others, we prove the convergence of preconditioned steepest d…
