One of the biggest benefits of the SMIRNOFF format is the ability to add new parameters without needing to add new chemical perception to any other parameter type. For example, in traditional force fields, when a new torsion is required, new atom type(s) must be created and then added to all other sections of the force field. However, in SMIRNOFF if a new parameter is needed, all one needs is the SMIRKS for that parameter and to add it to that section of the force field. While there is still science to be explored for the SMIRKS generation required for a general force field, there are smaller problems relevant to force field fitting where ChemPer could be more immediately useful.
