Computer programming may seem like magic these days, but most programs are built from conceptual steps that use visual aids to work out how the program needs to flow. Each function of a program can be ...

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 ...

A team of computer scientists has come up with a dramatically faster algorithm for one of the oldest problems in computer science: maximum flow. The problem asks how much material can flow through a ...
