In addition to quantitatively suboptimal (higher) reaction enthalpies, the greedy algorithms also lead to solutions that are qualitatively wrong, in the sense that some products predicted by the greedy heuristic are absent in the exact linear programming solution and vice versa. Stated more formally, �𝑖𝑖: 𝑥𝑥 𝑖𝑖 greedy ≠ 0� ≠ �𝑗𝑗: 𝑥𝑥 𝑗𝑗 LP ≠ 0�. In fact, a nonzero (negative) Δ𝐻𝐻 LP -Δ𝐻𝐻 Greedy value always corresponds to a qualitatively wrong solution for all four versions of the greedy algorithm. Values of Δ𝐻𝐻 ox calculated by different methods can be found in `output/oxidation_reaction_solution.7z` from the repository. As PBR calculations depend on the list of oxidation products, such qualitative differences would alter self-passivation results. .
