"After ranking, the most favorable potential degradation product is then be [sic] selected. The maximum amount of this product material that can be formed from the original material is calculated next. Finally, the formation energy for the creation of this quantity of product is logged, along with the remaining amount of original material. This process can then be repeated with the next most promising degradation product, based on its ranking parameter and the remaining material." This can be read this as either computing the ranking once and using the same ranking for subsequent reactions, or recomputing the ranking on each iteration. We denote the former "lazy" (as it avoids reranking) and the latter "diligent". Upon examination of their code, 10 it appears that Twyman et al. implemented the lazy variant. We consider both variants in our discussion below.
