Implementing and experimenting with variants of Weisfeiler-Leman graph stabilisation
AbstractWeisfeiler-Leman graph stabilisation is a procedure that plays an important role in modern graph isomorphism algorithms (L.Babai 2015) and enjoyed attention in machine learning community recently (cf. "Weisfeiler-Lehman graph kernels").
While it is relatively easy to implement, efficient portable implementations seem to be hard to find. In this project we will work on producing such an open-source implementation, either by reworking our old code from http://arxiv.org/abs/1002.1921 or producing new one; we will also work on providing Python/Cython interfaces for a possible inclusion in SageMath
(http://sagemath.org) library, and/or elsewhere.
