Optimizing low-thrust gravity assist interplanetary trajectories using evolutionary neurocontrollers
13 years 9 months ago
The combination of low-thrust propulsion and gravity assists allows designing high-energy missions. However the optimization of such trajectories is no trivial task. In this paper,...
