摘要：
The reciprocal degree resistance distance index of a connected graph G is defined as RDR(G) = Sigma({u,v}subset of V(G))((d(G)(u) + d(G)(v))/r(G)(u, v)), where r(G)(u, v) is the resistance distance between vertices u and v in G. Let B-n denote the set of bicyclic graphs without common edges and with n vertices. We study the graph with the maximum reciprocal degree resistance distance index among all graphs in B-n and characterize the corresponding extremal graph.
