Sensitivity analysis in the close boundary. The random seeds, based on a uniform distribution, were set to obtain the same initial arrays. Subfigures in lines show variations in the scale parameters, and columns show variations in the size parameters. Different colors in each plot represent iterations, starting from a uniform distribution. The model validation uses the parameters K1 = 0.1, K2 = 1.0, β = 1.0, and α = 0.3
