If you’ve been making the same commute for a long time, you’ve probably settled on what seems like the best route. But “best” is a slippery concept. Perhaps one day there’s an accident or road closure ...

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