AbstractWe present an empirical study of the accuracy-cost tradeoffs of Anderson's method. The various parameters that control the degree of approximation of the computational elements and the separateness of interacting computational elements govern both the arithmetic complexity and the accuracy of the method. Our experiment shows that for a given error requirement, using a near-field containing only nearest neighbor boxes and a hierarchy depth that minimizes the number of arithmetic operations minimizes the total number of arithmetic operations.
