The bottom panel of Figure zooms in on the region about the minima of the AVDZ and AVTZ curves, and there we add datapoints of the mean GEO values of functionals containing different amounts of the exact exchange. From there we can see that the performance of TPSSh and B3LYP is nearly the same as that of respective α-PBE. On the other hand, Minnesota functionals are typically better than the respective α-PBE functional (note that Minnesota functionals are designed so that their exchange and correlation parts fit each other). Only MN15/AVDZ gets beaten by α-PBE within the same amount of exact exchange and basis set, given the very good performance of α-PBE/AVDZ in the region around that α value. Finally, α-PBE at the optimal α = 0.36 value outperforms all functionals with AVDZ. When VDZ is used in place of AVDZ, the curve has nearly the same shape but is shifted upwards by ∼0.1 kcal/mol (see Figure ). In Figure , we also show the GEO boxplots of α-PBE for the B2se at the following α values: 0, 0.21 (the minimum of the AVTZ curve), 0.36 (the minimum of the AVDZ curve), 0.5. From these boxplots, we can see that at the two smaller α values the GEO spread within AVDZ is larger than that of AVTZ & AVQZ, whereas the situation is reversed at the larger two α values. This also suggest that α-PBE at α = 0.36 and with AVDZ provides great geometric performance relative to its cost.
