algorithm which includes in each iteration a CG-like step for modifying the right-hand side and a Kaczmarz-like step for … producing the approximate solution. We prove convergence of the hybrid algorithm for general inconsistent and rank …-deficient least-squares problems. Although the new algorithm has potential for more applied experiments and comparisons, we restrict …
