At the second graph tour I attended for Neo4j in Boston earlier this month, and the fourth event that has taken place so far, I got a fascinating update that showed how the use of graphs gradually ...

Graph polynomials serve as robust algebraic encodings of the intricate combinatorial properties inherent to graphs. At the heart of this discipline lies the Tutte polynomial, an invariant that not ...

In algorithms, as in life, negativity can be a drag. Consider the problem of finding the shortest path between two points on a graph — a network of nodes connected by links, or edges. Often, these ...
