On maximum residual block and two-step Gauss–Seidel algorithms for linear least-squares problems
The block Gauss–Seidel algorithm can significantly outperform the simple randomized Gauss–Seidel algorithm for solving overdetermined least-squares problems since it moves a large block of columns rather than ...
