I make short, to-the-point online math tutorials. I struggled with math growing up and have been able to use those experiences to help students improve in math through practical applications and tips.

I received a feature request from a graph scientist: the Weisfeiler-Leman (WL) graph isomorphism test, a popular heuristic for detecting non-isomorphic graphs. From what I understand, WL quickly ...

Given a pair of directed line graphs, the problem of ascertaining whether or not they are isomorphic is one for which no efficient algorithmic solution is known. Since a straightforward enumerative ...

ABSTRACT: To effectively evaluate a system that performs operations on UML class diagrams, it is essential to cover a large variety of different types of diagrams. The coverage of the diagram space ...

Covid-19 broke the charts. Decades from now, the pandemic will be visible in the historical data of nearly anything measurable today: an unmistakable spike, dip or jolt that officially began for ...

Group H( new Subgroup( S8, {{1,2,3,0,4,5,6,7},{0,1,2,3,5,6,7,4}} ) ); Group I( new Subgroup( S8, {{1,2,3,0,4,5,6,7},{0,1,2,3,5,6,7,4},{4,5,6,7,0,1,2,3}} ) ); ...

Abstract: Attributed graphs are widely used in many application domains, for example to model social networks. An attributed graph is a graph in which vertices and edges may have types and other ...

The original version of this story appeared in Quanta Magazine. Much of mathematics is driven by intuition, by a deep-rooted sense of what should be true. But sometimes instinct can lead a ...

Much of mathematics is driven by intuition, by a deep-rooted sense of what should be true. But sometimes instinct can lead a mathematician astray. Early evidence might not represent the bigger picture ...
