Babai's talks sketch a proof that shows that the graph isomorphism problem — determining whether two graphs are the same — can be solved much more quickly than was previously known.

But already in 1980, another classical theorem—the Babai-Erdős-Selkow theorem—showed that almost all graphs can be relabeled to make easy isomorphism testing possible.
This course examines the basic concepts and techniques of graph theory. The topics to be covered are: fundamental concepts, connectivity and matchings, colourings, extremal problems. Optional topics ...
We show that the groupoids of two directed graphs are isomorphic if and only if the two graphs are orbit equivalent by an orbit equivalence that preserves isolated eventually periodic points. We also ...
