\Delta E_{\text{hull}} = E(\text{compound}) - E_{\text{convex hull}}(\text{composition})

What this part means

The expressions on both sides represent the same quantity under the stated assumptions.

Its job in the formula

The equals sign connects the complete expression on the left with the complete expression on the right. Both sides must have compatible units.

The passage around this formula

If a screening model reports a stability margin against decomposition, $\Delta E_{\text{hull}} = E(\text{compound}) - E_{\text{convex hull}}(\text{composition})$ . then a small positive $\Delta$ $E_{\text{hull}}$ 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- $\Delta$ $E_{\text{hull}}$ 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…
