Cosmological N-body simulations.
Abstract
The authors discuss cosmological N-body codes with a special emphasis on particle mesh codes. They present the mathematical model for each component of N-body codes. They compare alternative methods for computing each quantity by calculating errors for each of the components. The authors suggest an optimum set of components that can be combined to reduce the overall errors in N-body codes.
