After training, the generator generates (B gen , P gen ) conditioning on (S gen , E gen ) and then we assemble them into crystal structures. When 10 millions materials are generated, we find that most of the cubic materials in Materials Project and ICSD can be rediscovered. Then we filter down 10 millions by pymatgen CIFs readability, charge neutrality, and predicted negative formation energy for DFT relaxation. In final, 506 dynamically and mechanically stable ternary and quaternary new-prototyped materials are confirmed via phonon dispersion and mechanical property calculations.
