What the article says around this equation
then a small positive has historically been treated as a proxy for “worth attempting to synthesize.” The 2024–2025 critique’s core point is that this proxy is weak: a large share of low- candidates in the GNoME set failed independent synthesizability screens once structural and existence-probability criteria were applied on top of the energy criterion alone [ 5 ] [ 10 ] . Closing the gap means replacing that single-variable proxy with a jointly trained, multi-criterion one — an analysis claim about what the fix would have to look like, not a report that anyone has yet built it at scale.
