The researchers conducted the research on molecular graphs of the generalized Somber index in tri-cyclic graphs and identified the extreme value of the generalized Somber index in tricyclic graphs to further study the characterization of molecular diagrams,predict the biological activity of compounds,and establish the relation-ship between molecular structure and properties.The result shows that the minimum Somber index over the set of base tricyclic graphs with n is attained in τn15(1,1,1,1,1).
