Math Games That Make You Think
In the echo chamber, social media kinda world that we’re living in, network theory is playing an increasingly important role. So I was delighted, this morning, to spend several minutes playing an interactive game by the talented Nicky Case called … Continue reading

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 co-blogger 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 Riemann-Roch 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, Riemann-Roch for Graphs and Applications, was not … Continue reading
