摘要
介绍了蒙特卡洛法和为求解复杂组合优化问题提出的蚁群算法,针对断层参数的特点,结合位错理论模型模拟的地面位移场数据对断层的三维滑动速率采用两种优化方法进行了反演计算,比较了两种优化算法的反演效果。结果表明:蚁群算法的可靠性和稳定性优于蒙特卡洛法。
The Monte Carlo and recently the ant colony algorithm which proposed for solving hard combinational optimization problems are introduced, And in view of the fault parameters characteristics, combined dislocation of the theoretical model simulated ground fault displacement field data on inversing the three-dimensional slip velocity with two kind of optimized methods, Compared the two optimization inversion results, The results show that ant colony algorithm is superior to Monte Carlo method in reliability and stability.
