A fast algorithm for particle simulations. (English) Zbl 0629.65005

A two-dimensional version of an algorithm is presented for the rapid evaluation of the potential and force fields in systems involving large number of particles whose interactions are gravitational in nature. For a system of N particles the suggested algorithm requires amount of work only of the order O(N) to evaluate all interactions to within roundoff error. A numerical example is also presented to illustrate the algorithm.
