An example is the method of Lewis Fry Richardson, and the methods developed by R. Over-relaxation methods had been used before the work of Young and Frankel. Frankel in 1950 for the purpose of automatically solving linear systems on digital computers. It was devised simultaneously by David M. A similar method can be used for any slowly converging iterative process.
In numerical linear algebra, the method of successive over-relaxation ( SOR) is a variant of the Gauss–Seidel method for solving a linear system of equations, resulting in faster convergence. Method of solving a linear system of equations
