Recycling Bi-Lanczos Algorithms: BiCG, CGS, and BiCGSTAB
Engineering problems frequently require solving a sequence of dual linear systems. This paper introduces recycling BiCG, that recycles the Krylov subspace from one pair of linear systems to the next pair. Augmented bi-Lanczos algorithm and modified two-term recurrence are developed for using the rec...
