Abstract
The three key translation equations of the fast multipole method (FMM) are deduced from the general polypolar expansions given earlier. Simplifications are introduced for the rotationβbased FMM that lead to a very compact FMM formalism. The optimumβparameter searching procedure, a stable and efficient way of obtaining the optimum set of FMM parameters, is established with complete control over the tolerable error (Ξ΅). This new procedure optimizes the linear scaling with respect to the number of particles for a given Ξ΅. In addition, a new parallel FMM algorithm, which requires virtually no internode communication, is suggested that is suitable for the parallel construction of Fock matrices in electronic structure calculations.

In this paper, new simpler optimization parameters for the nonstandard FDTD (NS-FDTD) method are proposed by redefining the spatial-difference operator. Consequently, the number of optimization parameters required in the method is reduced to one from two in 2D space, and three from nine in 3D space,
