Until now, the only known algorithms for accomplishing certain tasks required an amount of space roughly proportional to their run time, and researchers had long assumed there’s no way to do better.

Complexity theorists sort problems into categories, called complexity classes, based on the resource demands of the best algorithms for solving them — that is, the algorithms that run fastest or use ...

Technical Terms Complexity Theory: The study of the intrinsic difficulty of computational problems and the classification of algorithms according to the resources required for their solution.

Will algorithms designed for interconnected computers hold up if some of the machines are not here on Earth but flying about in space, onboard satellites or spacecraft? Subscribe to our newsletter ...

The researchers also considered an extension of the STSP that includes time windows for simultaneous pickups and deliveries, creating a more realistic and challenging problem. The core method involves ...
