✦ Synopsis

A method is proposed for calculating the forces in path integral theory and tested on semiclassic systems. It takes the range of the classic and quantum interactions into account and uses a second table within the neighbors table for the nearest neighbors. This method is found to be much more efficient than either the standard direct method or the traditional neighbors table, the efficiency increasing with the size of the system. The method can also be applied to clusters whose interaction centers are much farther apart than the distances between two consecutive members of the cluster.
