molecular entity quality smallest set of smallest rings 2022-07-11T08:18:30Z SSSR The Smallest Set of Smallest Rings (SSSR) is a subset of cycles within a molecular graph (ring). SSSR was the first widely-used cycle set to classify cyclic molecules in cheminformatics. It offers a limited solution to the problem of molecular cycle perception. Unlike the set of all cycles, an SSSR can filter useless or interfering envelope cycles, but offers no guarantee of uniqueness. A given molecular graph can produce multiple SSSRs with no constraints on which one will be obtained. https://depth-first.com/articles/2020/08/31/a-smallest-set-of-smallest-rings/
