Description

This method calculates the Randi\'c connectivity ID number.

Usage

1

Arguments

g

a graph as a graphNEL object.

deg

the degree of each node of g. Will be automatically calculated if not supplied.

Value

The resulting floating point value is a weighted path sum which stresses local features and takes the vertex degree into account.
