More Graph Isomorphism Drama
That plucky graph isomorphism problem is at it again! In November 2015, University of Chicago computer scientist Laszlo Babai announced an algorithm to determine whether two graphs are isomorphic in quasipolynomial time, and there was much rejoicing. (My coblogger Anna … Continue reading
Meanwhile Over In Computer Science
An algorithm has just been proposed for solving the graph isomorphism problem in quasipolynomial time, dealing a serious blow to hard problems all over the world. But let me first explain what all of those words mean. Graphs, you’ll recall, … Continue reading

How Quadratic Reciprocity Is Like Dealing Cards
Currently the RiemannRoch theorem is my nemesis, and I stumbled on Matt Baker’s math blog while I was looking for some help figuring out how to use it. The post I came across, RiemannRoch for Graphs and Applications, was not … Continue reading
