The author offers a numerical method for the solution of the discretized effective potentials and ground states for a class of problems involving classical one-dimensional chains of atoms with nearest neighbor interactions. The calculation time is found to vary linearly with the size of the grid, N, that is a significant advantage to some earlier algorithm where the calculation time varies as \(N^ 2\) or worse.
