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.
