IsomorphicQ
As of Version 10, most of the functionality of the Combinatorica package is built into the Wolfram System. »
IsomorphicQ[g,h]
yields True if graphs g and h are isomorphic.
Details and Options
- IsomorphicQ functionality is now available in the built-in Wolfram Language function IsomorphicGraphQ.
- To use IsomorphicQ, you first need to load the Combinatorica Package using Needs["Combinatorica`"].
- This function takes an option Invariants->{f1,f2,…}, where f1,f2,… 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}.
