Fig. 8: Global optimization of NbNO in a fixed cell with different ICE-groups.

Success curves for optimization of Nb8N8O8 from runs including ICE-groups containing NbNO (ICE Nb,N,O), NO (ICE N,O), NbO (ICE Nb,O), or no ICE-groups (BEACON). The inset shows the identified minimum-energy structure. The applied unit cell corresponding to the optimal structure from OQMD64. The error shading is based on Bayesian uncertainty estimation, as detailed in the methods section.
