There is a new sorting algorithm a deterministic O(m log2/3 n)-time algorithm for single-source shortest paths (SSSP) on ...

The candidates who make it past the algorithm play a set of 12 short online games developed by Pymetrics, which specializes in game- and algorithm-based candidate assessment and matching.

They started small, with algorithms that sorted only 3, 4, or 5 numbers at a time, but these are important because they’re used by algorithms that sort longer lists.
