Figure 3: MSE of in two-dipole localization using SA, GA, PSO, and DE with different initialization parameters, 2500 evaluations of the objective function and  dB. SA* correspond to the case of SA when . AFM refers to the case when adaptive feasible mutation was used for GA. For the PSO algorithm, was used in all cases. DE BC corresponds to the experiment using the generic strategy (DE/rand/1/bin) with and . The central mark in each method corresponds to its median, the edges of the box are the 25th and 75th percentiles, the whiskers extensions are the most extreme data points, and “+” markers correspond to the outliers.
