• Iterative methods for ill-posed problems and semiconvergent sequences (2006, background): “RRGMRES typically yields higher accuracy than GMRES when the right-hand side b is contaminated by error and the desired solution x̂ is smooth; see [2] for examples.”
• Arnoldi-Tikhonov regularization methods (2009, methodology): “The range-restricted GMRES (RRGMRES) iterative method is a variant of the (standard) GMRES method designed for the solution of large linear discrete ill-posed problems; see [6,26].”
