In chemical graph theory, many graph parameters, or topological indices, were proposed as estimates of molecular structural properties. Often several variants of an index are considered. The aim is to extend the original concept to larger families of graphs than initially considered, or to make it more precise and discriminant, or yet to make its range of values similar to that of another index, thus facilitating their comparison. In this paper, we introduce a new variant of the geometric-arithmetic index to get a better estimate of the boiling point. We compare the correlation between the boiling points and both versions of the geometric-arithmetic index using different regression models.
