We present IDR($s$), a new family of efficient, short-recurrence methods for large nonsymmetric systems of linear equations. The new methods are based on the induced dimension reduction (IDR) method proposed by Sonneveld in 1980. IDR($s$) generates residuals that are forced to be in a sequence of nested subspaces. Although IDR($s$) behaves like an iterative method, in exact arithmetic it computes the true solution using at most $N + N/s$ matrix-vector products, with $N$ the problem size and $s…

Algorithm 913: An elegant IDR(s) variant that efficiently exploits biorthogonality properties

This article derives a new IDR(s) variant, that imposes (one-sided) biorthogonalization conditions on the iteration vectors, and shows that the new variant is more stable and more accurate than the originals, and that it outperforms other state-of-the-art techniques for realistic test problems.

Exploiting BiCGstab(ℓ) Strategies to Induce Dimension Reduction

Through numerical experiments it is shown that IDRstab can outperform both IDR($s$) and BiCGstab($\ell$), and the relation between hybrid Bi-CG methods and IDR and the new concept of the Sonneveld subspace as a common framework is introduced.
