结论将遗传算法与二次规划相结合，开发了一种轨迹优化工具。当应用于高性能太阳帆转移到流离失所的NKO的飞行任务规划的困难问题时，它似乎可以相对容易地确定接近最佳的轨迹。传输时间损失（随着段数的增加，从传输时间收敛估计）即使对于少量段（四个或三个）也是可以接受的。少量的段减少了使用GA所带来的计算负担，并且在实践中简化了姿态控制。
Conclusions A trajectory optimization tool has been developed which hybridized a GA with SQP. When applied to the dif cult problem of preliminarymission planning for high-performancesolar sail transfers to displaced NKOs, it appeared to identify near-optimal trajectories with relative ease. The transfer time penalties (estimated from transfer time convergence as the number of segments was increased) appear acceptable even for a small number of segments (four or ve). A small number of segments reduced the computational burden imposed by using a GA and would simplify attitude control in practice.
