Fig. 3. Normalized range of Pareto optimal parameter values for the three vadose zone materials in the Spydia HYDRUS-1D model including the compromise solution (solid lines) and the Pareto extremes (dashed and dashed-dotted lines), i.e., the best-fit solutions for each of the individual objectives F₁–F₃: (a) using the NSGA-II algorithm, (b) using the MOSCEM-UA algorithm, and (c) using AMALGAM.
