Computer scientists have written a network flow algorithm that computes almost as fast as is mathematically possible. This algorithm computes the maximum traffic flow with minimum transport costs for ...

Sachdeva’s breakthrough challenges one of the most studied problems in computer science, known as maximum flow, which ...

The original version of this story appeared in Quanta Magazine. 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 ...

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 ...

One of the most well-established and disruptive uses for a future quantum computer is the ability to crack encryption. A new algorithm could significantly lower the barrier to achieving this. Despite ...

The original version of this story appeared in Quanta Magazine. One July afternoon in 2024, Ryan Williams set out to prove himself wrong. Two months had passed since he’d hit upon a startling ...

The key distinction between IT and Computer Science is in their focus and responsibility: the former is application-oriented, ...

In cybersecurity circles, they call it Q-day: the day when quantum computers will break the Internet. Almost everything we do online is made possible by the quiet, relentless hum of cryptographic ...
