Electrical conductivity profiles recovered for representative inversion schemes. The results come from Q-response inversion (left), full-VP (middle), and alternating approach using the Fibonacci linear update rule (right). In each case, the final inversion result (blue) is plotted together with the initial model (red) and the ground truth (light 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
