Minimum generalized degree distance of n-vertex tricyclic graphs

In (Hamzeh et al. in Stud. Univ. Babes-Bolyai, Chem., 4:73-85, 2012), we introduced a generalization of a degree distance of graphs as a new topological index. In this paper, we characterize the n-vertex tricyclic graphs which have the minimum generalized degree distance.
