The study of chemical compounds’ molecular structures is one of the most cutting-edge uses of graph theory,
along with computer science, nanochemistry, network design in electrical and electronic engineering, and the
depiction of graphs in Google Maps. The degree and distance between vertices of a graph are the basis for
examining topological indices. The formula for computing the Weighted Padmakar Ivan index (WPI) of a
graph G is
PIw(G) = P e∈E(G)
[(dG(u) + dG(v)][|V (G)| − NG(e)].
