61 Note also that Eq. (5) is a kind of recurrence relation, because the terminal Wiener index of a bigger graph (namely of Gp) is expressed in terms of the terminal Wiener index of a smaller graph (namely of G).This observation will be utilized in
The terminal Wiener index of a tree is the sum of distances for all pairs of pendent vertices, which recently arises in the study of phylogenetic tree reconstruction and the neighborhood of trees. This paper presents a sharp upper and lower bounds for the terminal Wiener index in terms of its order and diameter and characterizes all extremal trees which attain these bounds. In addition, we Abstract: The terminal Wiener index of a tree is the sum of distances for all pairs of pendent vertices, which recently arises in the study of phylogenetic tree reconstruction and the neighborhood of trees. This paper presents a sharp upper and lower bounds for the terminal Wiener index in terms of its order and diameter and characterizes all extremal trees which attain these bounds. The aim of this work is to explore the properties of the terminal Wiener index, which was recently proposed by Gutman et al. (2004) , and to show the fact that there exist pairs of trees and chemical trees which cannot be distinguished by using it.We give some general methods for constructing equiseparable pairs and compare the methods with the case for the Wiener index.

A simple formula for computing TW is obtained and the trees with minimum and maximum TW are characterized.
