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 ...

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.

Theoretical computer scientists are always probing the relationship of space (memory) and time. For 50 years, experts knew that a calculation of X steps required X/log X memory slots, but a new ...

As we stand on the brink of a new era in technological complexity, our approach to safety and reliability must evolve just as rapidly.
