Asymptotic convergence of restarted Anderson acceleration for certain normal linear systems

Oliver A. Krzysik, Hans De Sterck, Adam Smith

Anderson acceleration (AA) is widely used for accelerating the convergence of an underlying fixed-point iteration ${\mathbf{x}}_{k+1}=\mathbf{q}({\mathbf{x}}_k)$, $k=0,1,\dots$, with $\…
