Query: Reverse degree distance of unicyclic graphs   The reverse degree distance is a connected graph invariant closely related to
the degree distance proposed in mathematical chemistry. We determine the
unicyclic graphs of given girth, number of pendant vertices and maximum degree,
respectively, with maximum reverse degree distances.
