An Optimally Generalized Steepest-Descent Algorithm for Solving Ill-Posed Linear Systems
It is known that the steepest-descent method converges normally at the first few iterations, and then it slows down. We modify the original steplength and descent direction by an optimization argument with the new steplength as being a merit function to be maximized. An optimal iterative algorithm w...
