....box containing the cluster to the distance between body and cluster is smaller than some ffi. The precision of the force calculation can be improved by choosing a small ffi or, usually more efficiently, by using a higher order approximation of the cluster such as quadpoles [13] or hexadecapoles [19] instead of the center of mass monopole. 2.2 Adaptive FMM and Anderson In the Barnes Hut algorithm, interactions between bodies and sufficiently far away clusters are used to reduce the number of interactions from O(N 2 ) to O(N log N) in the uniform case. The FMM and Anderson s Method go one ....
