WebIn 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.A similar method can be used for any slowly converging iterative process.. It was devised simultaneously by David M. Young Jr. and by Stanley P. Frankel in 1950 for … Web7 de dez. de 2024 · In this video we are going to look at the SOR (Successive Over-Relaxation) improvement over the Gauss-Seidel.
WebThe SOR waveform relaxation and its convergence were first studied by Miekkala and Nevanlinna [25,26]. Reichelt et al. [27] improved the results by proposing a convolu-tion SOR acceleration of the waveform relaxation scheme in which, instead of multiplying by a fixed SOR parameter as in the traditional SOR approach, a time-dependent SOR Web15 de set. de 2008 · This paper studies the multi-splitting algorithm and the two-stage iterative method for waveform relaxation (WR) method, solving the initial value problems for linear systems of ordinary differential equations (ODEs) in the form y ′ (t) + Ay (t) = f (t).Convergence of both cases are analyzed when the coefficient matrix is Hermitian …
