"Witryna18 sie 2024 · My task is to make a Successive Over Relaxation (SOR) method out of this, which uses omega values to decrease the number of iterations. If omega = 1, it becomes Gauss-Seidel method, if < 1 - method of simple iterations, > 1 and < 2 - SOR. Obviously, with higher omega values the number of iterations should decrease.
