fies those with high Q(SG, P) values. In Figure (e), we show the 15,000 top-rated SGD solutions with respect to the quality function (Eq. 4). These solutions are shown in a utilityfunction (u(SG, P)) vs. coverage plot. The SG maximizing Q(SG, P), denoted σ max(Q) , has a ∆d C-O max mean of 0.118 Å, a coverage of 0.387, and is displayed in green in Fig. ). We introduce the rules associated with σ max(Q) and the corresponding surface sites in the ESI Section 3.3. This SG contains surface sites associated with larger bond elongation compared to the entire data set. Nevertheless, σ max(Q) includes a significant fraction of systems with relatively small values of ∆d C-O max .
