“…This problem consists in finding suitable parameter values which are used to define a trajectory for a space vehicle. The literature on this subject is quite vast -we refer the readers, e.g., to (Addis, Cassioli, Locatelli, & Schoen, 2009;Izzo, Becerra, Myatt, Nasuto, & Bishop, 2007;Olympio & Marmorat, 2008;Vasile, 2005) for references on this subject. Here it may suffice to say that this is a family of very hard global optimization problems with relatively few variables (a few tens at most) but a huge amount of local optima.…”
