Convergence and Semi-convergence of a class of constrained block iterative methods
Mahdi Mirzapour, Andrzej Cegielski, Tommy Elfving
In this paper, we analyze the convergence %semi-convergence properties of projected non-stationary block iterative methods (P-BIM) aiming to find a constrained solution to large li…
