Interfacing Python and NetworkX with VF3 – the fastest algorithm for graph/subgraph isomorphism calculation

VF3Py

Interfacing Python and NetworkX with VF3 – the fastest algorithm for graph/subgraph isomorphism calculation.

Setup

Make sure that your OS is Linux and Python version is >= 3.8.

VF3Py can be installed using this command:

pip install vf3py

Test your installation:

$ python
>>> import vf3py.test
>>> vf3py.test.run_tests()
(...lots of output...)
OK
>>>

Other projects that use VF3Py

For now, all projects are mine:

• algebra_repr (TODO: come up with a better name) -- uses SageMath to construct finite algebraic structures (groups, rings, fields), then represents them as graphs. Graph isomorphism allows to check if any two algebraic structures are isomorphic or not.

• PyXYZ -- A Python Library for Molecular Geometry Manipulation. TODO: Use VF3Py to generate automorphisms groups for molecular graphs.
