Hard in theory, easy in practice: Why graph isomorphism algorithms seem to be so effective

Graphs are everywhere. In discrete mathematics, they are structures that show the connections between points, much like a ...

Finally, a Fast Algorithm for Shortest Paths on Negative Graphs

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 ...
