Modified iterated Tikhonov methods for solving systems of nonlinear ill-posed equations
(2011)We investigate iterated Tikhonov methods coupled with a Kaczmarz strategy for obtaining stable solutions of nonlinear systems of ill-posed operator equations. We show that the proposed method is a convergent regularization ... -
On Steepest-Descent-Kaczmarz methods for regularizing systems of nonlinear ill-posed equations
(2008)We investigate modified steepest-descent methods coupled with a loping Kaczmarz strategy for obtaining stable solutions of nonlinear systems of ill-posed operator equations. We show that the proposed method is a convergent ...
