Autonomous computations that rely on automated reaction network elucidation algorithms may pave the way to make computational catalysis on a par with experimental research in the field. Several advantages of this approach are key to catalysis: (i) automation allows one to consider orders of magnitude more structures than what would be accessible by manual inspection, eventually with full resolution of structural varieties and conformations as well as with respect to the type and number of… Expand
