摘要
综述了大地测量反演算法的发展状况 ,详细介绍了模拟退火、随机耗费和区间算法等 3种优化方法 ,并基于位错模式 ,采用模拟的重力测量观测数据 ,比较了 3种算法的反演效果。结果表明 :模拟退火法优于随机耗费法 ,而区间算法的可靠性又优于模拟退火法 ;区间算法是最可靠的反演方法。
Inversion can be considered as an optimization process. The progress of geodetic inversion algorithm is summarized in this paper. Three optimization method:simulated annealing method, random cost and interval algorithm method are introduced and compared in inversion effect with synthetic gravimetry data based on dislocation model. The results show that simulated annealing method is superior to random cost method and interval algorithm is superior to simulated annealing. Thus the conclusion that the interval algorithm is the most reliable method is drawn.
