WebSep 16, 2024 · An unlabeled tree encodes only the structure and nothing more since there is nothing associated with nodes. Unlabeled trees are studied in combinatorics, could be used to represent molecular structures, and in general to represent different kinds of automata and study isomorphism between structures.
