Relaxation factor of the introduction (" relaxation method is the Gauss- Seidel iteration method for an accelerated method, the basic idea is to Gauss- Seidel iteration the first k+1 obtained for solution vector with the first k for solution vector as the weighted average, power factor (ie the relaxation factor) w option is appropriate to accelerate the effect is obvious. Therefore, this method is how to select the most critical optimal relaxation factor. " ) and algorithms.
