Distance-based metrics has been practiced to various wide-ranging physicochemical
applications, especially in the characterization and modeling of chemical structures …

A graph is said to be a regular graph if all its vertices have the same degree, otherwise, it is
irregular. Irregularity indices are usually used for quantitative characterization of the …

In many applications and problems in material engineering and chemistry, it is valuable to
know how irregular a given molecular structure is. Furthermore, measures of the irregularity …

A topological index is a numerical quantity connected with a graph describing the molecular
topology of the graph. It can predict different physicochemical properties such as boiling …

Topological indices (TIs) transform a molecular graph into a number. The TIs are a vital tool
for quantitative structure activity relationship (QSAR) and quantity structure property …

Very recently, a bond‐additive topological invariant, known as the Mostar index, has been
described as a measure of peripherality in networks and graphs. Since then, more versions …

Topological descriptors are the numerical quantities of a graph that characterize various
structural properties of it. In environmental sciences, pharmacy and in mathematical …

Topological indices have been computed for various molecular structures over many years.
These are numerical invariants associated with molecular structures and are helpful in …

Irregularity indices are usually used for quantitative characterization of the topological
