Abstract�� The optimization of Lambert two-impulse transfer was studied. The traditional optimization methods were inefficient or even ineffective for the Lambert transfer with unfixed initial position, final position and transfer time, because of various variables and the complexity of equations. The adaptive genetic algorithm (AGA) was adopted to find the optimal variables. Meanwhile, the adaptive simulated annealing genetic algorithm (ASAGA) was developed by combining AGA and simulated annealing algorithm. The new algorithm not only provided global search capacity, but also improved local search capacity of AGA. The optimization results of AGA and ASAGA were compared. The results validate the effectiveness of two algorithms, and also the stronger search capacity of ASAGA.
