The dataset for benchmarking comprised a total 10570 unique crystals from the Materials Project database with ~6000 ternaries, ~4000 binary, ~500 quaternary, and the rest of unary, and pentanary materials with around ~40% of the structures being cubic (see supplementary Fig. )). All the structures considered are having formation energy within 200meV above the convex hull and configurations with negative Vickers hardness or shear modulus were excluded. The reported elastic moduli were computed using density functional theory as implemented in the Vienna Ab Initio Simulation Package (VASP) software.
