Extremal hyper-Zagreb index of trees of given segments with applications to regression modeling in QSPR studies

Extremal hyper-Zagreb index of trees of given segments with applications to regression modeling in QSPR studies

Introduced by Gutman & Trinajstić in 1972, the two well-known Zagreb indices efficiently determine the total π-electron energy of alternant hydrocarbons. The hyper-Zagreb index is a variant of the classical first Zagreb index. A tree is an acyclic graphical structure. A segment in a tree is...
