Otherwise, to understand the effect of we will rearrange the above equation to: If, then the method is exactly the Gauss-Seidel method. Where can be obtained using Equation 1 in the Gauss-Seidel method. The successive over-relaxation (SOR) method is another form of the Gauss-Seidel method in which the new estimate at iteration for the component is calculated as the weighted average of the previous estimate and the estimate using Gauss-Seidel :
