用改进的SPEA求解轨道转移的时间-能量极小化问题

Solving Minimizing Time-Energy Problem of Orbital Transformation via the Improved SPEA

提出了改进的SPEA,这是一种多目标进化算法。适于求解大尺度空间的多目标优化的Pareto最优解。并应用于求解轨道转移的时间—能量极小化问题,计算结果表明算法的有效性。

An improved SPEA, which is a multiobjective evolutionary algorithm be pointed out. And the algorithm has high capability to solve problems denned in large scale space compared to the old one. On applying the algorithm to solve minimizing time-energy problem of orbital transformation which is always encountered in space mission, the computing results show that the algorithm is valid and efficient.
