Details
- To use
, you first need to load the Combinatorica Package using Needs["Combinatorica`"]. - This function takes an option Invariants->{f1, f2, ...}, where
are functions that are used to compute vertex invariants. These functions are used in the order in which they are specified. - The default value of Invariants is {DegreesOf2Neighborhood, NumberOf2Paths, Distances}.
