There is a new sorting algorithm a deterministic O (m log2/3 n)-time algorithm for single-source shortest paths (SSSP) on directed graphs with real non-negative edge weights in the comparison-addition ...

The CodeChef IDE lets you code right in your browser, making it easy to start practicing with their problem sets. Understanding time and memory limits is key; your code needs to be both fast and ...

A canonical problem in computer science is to find the shortest route to every point in a network. A new approach beats the classic algorithm taught in textbooks.

Algorithms mirror flaws and fuel mistrust. Surveillance erodes privacy. Mindful choices, collective action—laws, literacy—can reclaim humanity.

Thinking about getting good at competitive programming, especially on a platform like CodeChef? It can seem like ...
