Reconstruction energy error at first 100 decomposition levels for 5 optimization algorithms in 4 different typical real-valued signals. Four figures compare the reconstruction energy error at first 100 decomposition levels for the conventional search method, the NM algorithm, the UKF method, the GA, and the PSO algorithm in the heavisine signal, the doppler signal, the bump signal, and the block signal
