Computing the set of Epsilon-efficient solutions in multiobjective space mission design [PDF]

open access: yes, 2011
In this work, we consider multiobjective space mission design problems. We will start from the need, from a practical point of view, to consider in addition to the (Pareto) optimal solutions also nearly optimal ones.
