Computer scientists are abuzz over a fast new algorithm for solving one of the central problems in the field. (January 15, 2017, update: On January 4, Babai retracted his claim that the new algorithm ...

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 ...

Vital nodes refer to specific nodes within a network that can exert a greater influence on the structure and functionality of the network compared to other nodes. During the past decades, people ...

A couple of weeks ago, I attended and spoke at the first stop in the Neo4j GraphTour in Washington D.C. and I was able to get the best answer yet to a question that I’d been pondering: what’s the ...

Most of you have used a navigation app like Google Maps for your travels at some point. These apps rely on algorithms that ...
