Visualization of obtained function φ minima (Q φ series) for λ = 0.1 (a), λ = 0.5 (b), λ = 0.9 (c) resulting from 100 experiments. The horizontal axis stands for the experiment number, the vertical axis stands for the numerical order of the synthesized data hour, and the color represents the Q φ values. b Red lines indicate the mean time moments corresponding to the values of the Q φ local maxima for all the computational experiments with λ = 0.5
