This paper presents the use of particle swarm optimization (PSO) for optimizing the time and propellant consumed in low-thrust and finite-thrust transfers between halo orbits of various amplitudes in the Earth-Moon system, using the circular restricted 3-body problem dynamics. PSO is employed to find the optimum thrust pointing angles and the time of the transfer trajectory. The algorithm is able to determine optimum transfer trajectories between halo orbits around Earth-Moon L1 and L2 libration points for continuous low-thrust trajectories, as well as for finite-thrust trajectories with and without an assumed coasting arc.
