In this paper, we investigate the construction methods of semiconvergent iterations and extrapolated iterations for solving singular linear systems. The skillful constructive criteria for semiconvergence of iterative and extrapolated iterative methods and the choices of the extrapolated parameter are presented. Furthermore, some construction methods of semiconvergent splitting of positive semidefi-nite matrix and singular M-matrix are discussed.
