Wiener Indices of Interval-Valued Fuzzy Graphs
Abstract: The Wiener index of a graph G is defined as the sum of the distances between all unordered pairs of vertices. In this paper the Wiener index and hyper-Wiener index of interval-valued Pythagorean fuzzy graph, interval-valued complex Pythagorean fuzzy graph, interval-valued picture fuzzy graph, interval-valued intuitionistic fuzzy graph, and interval-valued Fermatean neutrosophic graph are investigated.
Keywords: Distance, edge length, interval-valued fuzzy graph, membership value, non-membership value, Pythagorean fuzzy graph, Wiener indices
