DETERMINATION OF THE CRYSTAL-BASEMENT FROM GRAVITY DATA USING GENETIC ALGORITHMS

Abstract

The genetic algorithms (GA) are frequently used for searching and optimizing problems for excluding of computational complexity. In this paper we use Matlab and GA are used to compute the inversion problem of gravity Bouguer data with the sub space technique. First, GA was applied upon 33 points of a gravity model calculated with the 2-D formula for a gravity anomaly caused by a polygonal source in two cases with and without the density contrast; then the GA was applied to interpret a profile of gravity Bouguer data in the South of Vietnam.
