Genetic algorithm applied in a geoelectrical prospecting method

This work presents an optimization methodology using a Genetic Algorithm, to obtain the parameters of a soil that can be represented in a multi layer structure. The method uses a curve of experimental apparent resistivity obtained from measurements made in the soil. This experimental curve is compared with another curve of theoretical apparent resistivity of the soil, produced by the genetic algorithm. The main difference of this method regarding the already developed methods, is just that, besides optimizing the resistivities ρi and the thicknesses hi of each layer, the proposed method also optimizes the layers N quantity, seeking the best soil stratification. The obtained results of this work are compared with others soil stratification methods.
