Can we see the arrow of time? Algorithm can determine, with 80 percent accuracy, whether video is running forward or backward Date: June 19, 2014 Source: Massachusetts Institute of Technology ...

Time and memory (also called space) are the two most fundamental resources in computation: Every algorithm takes some time to run and requires some space to store data while it’s running.

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 ...
