POMULT: a program for computing periodic orbits in Hamiltonian systems based on multiple shooting algorithms. The author presents a Fortran 77 code for locating periodic orbits and equilibrium points in Hamiltonian systems. The method is based on the use of multiple shooting algorithms. It utilizes a damped Newton-Raphson method. It provides routines for computing fast Fourier transform of trajectories, Poincaré surfaces of sections, maximum Lyapunov exponents. The program’s name is POMULT available without licensing provision from CPC Program Library, Queens University of Belfast, Ireland. (Source: http://cpc.cs.qub.ac.uk/summaries/)
