In most cases, the first SMIRKS pattern will have all of its decorators removed resulting in a fully generic pattern. For example, [*:1]∼[*:2]∼[*:3] will match any three atoms (*) connected by any two bonds (∼), initially capturing any angle fragment. Due to the hierarchical nature of parameter assignment, this generic pattern will be matched to any fragment that doesn't match the patterns below. Some decorators consistently which remain in both reductions seem to capture the central chemistry. In parameters a7, a8, a9, and a13 the chemical feature which most affects the parameter is the size of the ring the angle is a part of. For both reductions, the ring size remains in the decorators on the central atoms. However, for other parameters the final decorators may not be the best combination. For example, in the first reduction for a2 the only decorators stored is the total hydrogen count on the central bond (H2) and than the bonds are not in a ring (!@). In this set of molecules, there is not much chemical diversity so this combination of decorators will match all of the necessary angles. However, in a more diverse set we can imagine wanting this angle to match hydrogen-carbon-hydrogen angles on a carbon with more than two hydrogens and we wouldn't want this same parameter to be applied to a non-carbon central atom. With this test, we had initial success in quickly generating SMIRKS to match the typing in smirnoff99Frosst, but there is still work to be done to optimize the Reducer.
