Conjugate gradient for ill-posed problems: regularization by preconditioning, preconditioning by regularization

Ahmed Chabib, Jean-Francois Witz, Vincent Magnier +1

This paper investigates using the conjugate gradient iterative solver for ill-posed problems. We show that preconditioner and Tikhonov-regularization work in conjunction. In partic…
