The paper is concerned with the construction of smoothly convergent variants of any iterative algorithm for solving non-symmetric linear systems. For this purpose quasi-minimal residual (QMR) algorithms, which include two- or three- or alternating two- and three-term recurrences, are proposed. It is shown that the QMR approach can also be applied to a breakdown avoiding algorithm.
