GGen exploration results for Al-C-Mn
GGen ran 1,500 trials across 100 Al-C-Mn stoichiometries in 34.7 min, keeping 1,435 relaxed structures. 90 of them landed within 150 meV/atom of the convex hull, 90 of which the database had not seen before. The leading generated candidate is Al3CMn5 in Pmmm (#47), which sits 22 meV/atom above the hull (new composition).
