论文摘要
在本文中，解决了通过使用NSGA II进行多目标优化的地震数据反转问题的解决方案。地震反演包括从海浪的旅行时间通过发射器和地震波的接收器估算地下的岩石缓慢。反转过程使用多目标优化技术，其中有必要估计不合适的功能和稳定约束之间的权衡。使用的约束是经典的一阶Tikhonov。选择了倾斜层的合成模型。获得的结果是可以接受的。基于与解决方案相关的累积误差的图，它的估计正确，也就是说，使用的优化方法有效地获得了可接受的结果，此外还解决了处理过的逆问题的不稳定性问题。另一个重要的结果是在帕累托边境上实现了收敛曲线，这是未来研究的重要结果。
In the present paper, the solution of the seismic data inversion problem through multi-objective optimization with NSGA II is addressed. The seismic inversion consists of estimating the slowness of rocks in the subsurface from the travel times of the waves through the transmitters and receivers of the seismic waves. The inversion process uses the multi-objective optimization technique, in which it is necessary to estimate the trade-off between the misfit functional and the stabilizing constraint. The constraint used was the classic first-order Tikhonov. A synthetic model of inclined layers was chosen. The results obtained were acceptable. Based on the graph of the cumulative errors related to the solution, it was estimated correctly, that is, the optimization method used was effective to obtain acceptable results, in addition to the constraint solving the instability problem of the inverse problem treated. Another important result was the achievement of a convergence curve on the Pareto frontier, an important result for future research.
