traveling salesperson problem

To understand what quantum computers can do — and what they can’t — avoid falling for overly simple explanations.

After 44 years, there’s finally a better way to find approximate solutions to the notoriously difficult traveling salesperson problem.

A new proof from the Australian science fiction writer Greg Egan and a 2011 proof anonymously posted online are now being hailed as significant advances on a puzzle mathematicians have been studying for at least 25 years.

The real-world version of the famous “traveling salesman problem” finally gets a good-enough solution.

Three computer scientists have solved a problem central to a dozen far-flung mathematical fields.

An infinitesimal advance in the traveling salesman problem breathes new life into the search for improved approximate solutions.
