Title: The Differential Evolution Algorithm in Geophysical Inversion
Abstract: This study introduces the differential evolution(DE) algorithm into geophysical nonlinear inversion to avoid the problems in traditional linear inversion methods,i. e. over-dependence on choice of the initial model,which leads to local optimal solution. We have established a nonlinear inversion model using the DE algorithm exemplified by electric sounding. A comparison between the model and real data shows that the DE algorithm is more accurate and faster than existing algorithms in inversion calculation. It can be further applied to two-dimensional or three-dimensional electrical sounding inversion. We also successfully applied this algorithm to data processing for polymetallic ore exploration in Inner Mongolia.
