GTOC5: Results from the Politecnico di Torino and Università di Roma Sapienza

Problems that concern a large number of possible targets, such as those typical of Global Trajectory Optimization Competitions (GTOC), require a global search for the optimal solution and a local refinement. During the 5th edition of the Global Trajectory Optimization Competition, we used different approximated techniques to perform a global search of suitable asteroid sequences; a lo-cal optimization method based on an indirect approach was then used to verify the feasibility of the suggested legs and perform the optimization of multi-leg sequences. All the tools used by our team are presented in this paper. The best solution found is described and discussed
