WebAbstract: In this paper, we combine the concepts of hyper-volume, ant colony optimization and nondominated sorting to develop a novel multi-objective ant colony optimizer for global space trajectory optimization. In particular, this algorithm is first tested on three space trajectory bi-objective test problems: an Earth-Mars transfer, an Earth-Venus transfer … WebIf an open-loop control is desired, the multiple solutions resulting from the inverse prediction queries are used to plan a trajectory in the joint space, as described with more detail in Section IV. This results in a general, learning based control scheme that can be switched from closed to open-loop at an y time, either due to a high
