1st ACT global trajectory optimization competition: Tsinghua University results

We present the results obtained for the 1st ACT Global Trajectory Optimization Competition. To simplify this complicated interplanetary trajectory design problem, the escape velocity, the thrust history and the impact point were imposed, and gravity assists were not considered. A genetic algorithm was employed to implement the optimization. The initialization of the algorithm and our result are given in detail. Though the method proved practicable for the imposed problem, final rank of the competition showed that our result was far from global optimum due to these superfluous simplifications. Our further work after the competition is also mentioned in brief.
