Vertex degree weighted path indices
Vertex degree weighted path indices PN(a, b, ...), for example P1(a, b), P2(a, b, c), P3(a, b, c, d), and P4(a, b, c, d, e), are good topological indices for some of the physicochemical properties of octanes with |R|max up to 0.999. Mutually optimized combinations of them are even better, R (P1..P4)...

| description | Vertex degree weighted path indices PN(a, b, ...), for example P1(a, b), P2(a, b, c), P3(a, b, c, d), and P4(a, b, c, d, e), are good topological indices for some of the physicochemical properties of octanes with |R|max up to 0.999. Mutually optimized combinations of them are even better, R (P1..P4) is in the worst tested case > 0.9. The best results are obtained in mutually optimized combinations of some of them with some of the elements of the Universal matrix, in the worst tested case R = 0.994. Some of the vertex degree weighted path one indices give rise to a "regular" sequence of octane isomers of increasing branching. |
