In this paper, four novel topological indices named as neighbourhood version of forgotten
topological index (F_N), modified neighbourhood version of Forgotten topological index ($
F_N^* $), neighbourhood version of second Zagreb index ($ M_2^* $) and neighbourhood
version of hyper Zagreb index ($ HM_N $) are introduced. Here the relatively study depends
on the structure-property regression analysis is made to test and compute the chemical
applicability of these indices for the prediction of physicochemical properties of octane …

In this paper, four novel topological indices named as neighbourhood version of forgotten
topological index (𝐹, modified neighbourhood version of Forgotten topological index (𝐹∗),
neighbourhood version of second Zagreb index (𝑀∗ and neighbourhood version of hyper
Zagreb index (𝐻𝑀 are introduced. Here the relatively study depends on the structure-
property regression analysis is made to test and compute the chemical applicability of these
indices for the prediction of physicochemical properties of octane isomers. Also it is shown …
