AMOSA test with noise data for Model-1, a three-layered model with low resistivity in the middle. (a) inversion result, (b) the distribution of Archived points’ set in the inversion progress, and (c) curves of TEM data with or without noise and 5% Gaussian noise data used. The model and inversion parameters are listed in Table 1. In (b), the solid dots correspond to the PO front while the hollow dots are Non-PO front but once archived. In (a), the inversion result with or without noise is the average inversion result of three best solutions with minimum model fitting errors on PO front. The inverted results are in good agreement with the true model in solid line as well, even with noisy data. Also in (c), the decay data of inversion result with noise fits well with the real model data.
