Abstract
For solving rank deficient linear least squares problems, unsymmetric
successive overrelaxation (USSOR) type methods are investigated by some
researchers recently. In this note, we continue to study the USSOR method
for solving rank deficient linear least squares problems and obtain the
optimal iteration parameters and the corresponding optimal convergence
factors. Numerical experiments are given to examine the feasibility and
effectiveness of the USSOR method with optimal parameters.
