The Study of Geophysical Inversion Based on the Differential Evolution in Mineral Exploration

摘要

We introduce the differential evolution (DE) algorithm in the geophysical nonlinear inversion field. We set up a nonlinear inversion model of DC electrical sounding data using the DE algorithm. A comparison between the model and actual data suggests that the DE algorithm is more accurate and faster than existing algorithms. The study results presumably open new vistas in geophysical nonlinear inversion, and the DE algorithm may find application in two-dimensional or three-dimensional electrical sounding inversion. In the end, we applied the DE algorithm to the poiymetallic ore exploration successfully in Inner Mongolia.
