An overview of approaches for the stable computation of hybrid BiCG methods
Some approaches that help to reduce the effects of local rounding errors in the BiCG iteration coefficients in hybrid schemes are presented. For example, a stabilization technique for the \(\text{BiCGstab}(l)\) method is proposed. Furthermore, look-ahead strategies for the determination of appropriate values for \(l\) in \(\text{BiCGstab}(l)\) are discussed. Some numerical examples show the advantages of the proposed methods.
