“…In contrast, scenarios wherein the targets and the order of encounter are not pre-defined have, thus far, rarely been applied to the particular problem of debris mitigation, though recently Missel and Mortari have applied a genetic algorithm to path pre-planning (Missel and Mortari, 2013) and Barbee et al. examined a model of the Traveling Salesman Problem (Barbee et al, 2012). Furthermore, although not focused on debris mitigation, Ceriotti and Vasile incorporated an ant colony optimization algorithm within a scheme to generate interplanetary gravity-assist trajectories (Ceriotti and Vasile, 2010).…”
