Congratulations to Dr. Tzyy-Shyang Lin, Nathan J. Rebello, Guang-He Lee, and Melody A. Morris for their publication in ACS Polymers Au on a new canonicalization method for the BigSMILES line notation! In one approach, linear polymers can be converted into regular languages, and the minimal deterministic finite automaton can be constructed and associated with each distinct polymer.
