Abstract

Abstract

The purpose of this paper is to inverse directly the multi layer density interface by means of genetic algorithms, one of the global optimization methods. At first, this paper presents the improvement of the genetic algorithm in line with the gravity inversion for the combination of the determination of the exchange positions with the fitting of the gravity anomaly during the exchange of the genes in the genetic algorithm. In this case, the genetic algorithm appropriate to the gravity inversion can be obtained. Then, this paper presents the direct inversion of the multi layer density interface using this improved GA. The results of the theoretical model and field section show that this kind of improvement is effective.
