Comparison between the Second Zagreb Eccentricity Index and Eccentric Connectivity Index of Graphs (CTCSA)-Lupinepublishers

Comparison between the Second Zagreb Eccentricity Index and Eccentric Connectivity Index of Graphs by Kexiang Xu in Current Trends in Computer Sciences & Applications in Lupine Publishers

For a graph G, the second Zagreb eccentricity index E2(G) and eccentric connectivity index ∈c (G) are two eccentricity-based invariants of graph G. In this paper we prove some results on the comparison between 2E (G) m and c (G) n ξ of connected graphs G of order n and with m edges.  The authors demonstrated how a combination of both techniques and human interventions enhances control, decision-making and data analysis systems.
