Estimating Optimum Overrelaxation Parameters

finding the optimum overrelaxation parameter o¡¡, is an important and often a difficult part of the problem [1, p. 257]. When A is a 2-cyclic, consistently ordered, real symmetric, positive-definite matrix (this will be assumed in the rest of the paper), only the spectral radius p(£i) of the associated Gauss-Seidel iteration matrix £i is needed to determine the optimum parameter co¡, [2, p. 109...

Optimum Accelerated Overrelaxation Method

In this paper we give the optimum parameters for the Accelerated Overrelaxation (AOR) method in the special case where the matrix coefficient of the linear system, which is solved, is consistently ordered with nonvanishing diagonal elements. Under certain assumptions, concerning the eigenvalues of the corresponding Jacobi matrix, it is shown that the optimum AOR method gives better convergence ...

The Best Values of Parameters in Accelerated Successive Overrelaxation Methods

In this paper we find the best values of parameters in accelerated successive overrelaxation method (ASOR). We state and prove some theorems that show how we can find the optimal values of parameters in ASOR for special coefficient matrices. Key-Words: Linear systems, iterative methods, relaxation, ASOR.

Quantitative parameters in corpus design: Estimating the optimum text size in Modern Greek language

The aim of this paper is to investigate the major quantitative parameters related to the definition of the optimum text size in Modern Greek corpus development. Using the Hellenic National Corpus (HNC) (Hatzigeorgiu et al., 2000) as a reference point we estimated a number of critical statistical measures regarding feature counting in different text sizes. The results indicate that frequent ling...

Accelerated Overrelaxation Method

This paper describes a method for the numerical solution of linear systems of equations. The method is a two-parameter generalization of the Successive Overrelaxation (SOR) method such that when the two parameters involved are equal it coincides with the SOR method. Finally, a numerical example is given to show the superiority of the new method.
