Over relaxation
WebIterative Methods: SOR Method The Successive Over-Relaxation (SOR) 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 :. where can be obtained … WebRed-Black Successive Over-Relaxation (SOR) is a method of solving partial differential equations. In the parallel version, the program divides the red and the black array into roughly equal size bands of rows, assigning each band to a different processor. Communication occurs across the boundary rows between bands.
