Wiener index and Steiner 3-Wiener index of graphs

Asian-European Journal of Mathematics, 2021
Let [Formula: see text] be a set of vertices of a connected graph [Formula: see text]. The Steiner distance of [Formula: see text] is the minimum size of a connected subgraph of [Formula: see text] containing all the vertices of [Formula: see text].

Wiener index revisited

Chemical physics letters, 2001
We introduce a modification of the Wiener index. This modified Wiener index has a structural interpretation in terms of the greater weights of outer than inner bonds in a saturated hydrocarbon. Both the Wiener index and its modification together with the molecular polarity index lead to comparable structure-property models.
