Extremal Values of Randić Index among Some Classes of Graphs
Suppose G is a simple graph with edge set EG. The Randić index RG is defined as RG=∑uv∈EG1/degGudegGv, where degGu and degGv denote the vertex degrees of u and v in G, respectively. In this paper, the first and second maximum of Randić index among all n−vertex c−cyclic graphs was computed. As a cons...
