Electrical conductivity profile recovery for variants of VP. The results come from full-VP method (left), VP-RW2 (middle), and VP-RW3 approximation schemes (right). In addition to the ground truth (light blue), the initial model (red), and the final inversion result (blue), the intermediate models along the iterations are also plotted in gray scale, color-coded by iteration numbers. Light gray corresponds to early iterations, while dark gray corresponds to later iterations
