We propose and study two inversion procedures for the characterization of a nanostructure from near-field scattered intensity data. For this approach, the inverse problem is reformulated as a non-linear constrained optimization problem. The solution of the resultant fitness function is found through the application of the (μ/ ρ, λ) and (μ/ ρ + λ) strategies. The performance of the inversion algorithms is illustrated through an example and the results are discussed by means of a comparison between the methods proposed.
