The original version of this story appeared in Quanta Magazine. Computer scientists often deal with abstract problems that are hard to comprehend, but an exciting new algorithm matters to anyone who ...

The library sorting problem is used across computer science for organizing far more than just books. A new solution is less than a page-width away from the theoretical ideal. Computer scientists often ...

In a Directed Acyclic Graph (DAG), topological sorting is the process of linearly ranking vertices so that, for each directed edge u-v, vertex u appears before v in the ordering. Cycle Detection: Both ...
