“…In the above-mentioned work and related literature, we found that the step size, which is under the control of norm ∥A * A∥, is required for the convergence of iterative schemes. To overcome this regulation, a new form of iterative schemes have been proposed, see, e.g., [16][17][18][19]. L ópez et al [20] proposed a relaxed iterative scheme for (S p FP):…”
