Fig. reports the performance metrics of qNEHVI-BO and EGBO with post-repair (dash line) and prerepair (solid line), compared to a pure Sobol sampling (grey line). We see an increase of the HV with the pre-repair process for both qNEHVI-BO and EGBO, meaning that the algorithms get closer to the true PF. Furthermore, the NU metric for the pre-repair process remains as low as pure Sobol sampling, suggesting a quite uniform sampling of the PF, as already suggested by Fig. .
