single_source_shortest_path_faster_nonnegative (611B)


      1 # Single source shortest path faster nonnegative
      2 
      3 Solving [single_source_shortest_path] on [directed_graphs] with nonnegative weights faster than [Dijkstra's_algorithm]
      4 
      5 [duan2023randomized] gives a faster algorithm but on [undirected_graphs] only
      6 
      7 [duan2025breaking], in O(m log^{2/3} n)
      8 - explained in https://www.quantamagazine.org/new-method-is-the-fastest-way-to-find-the-best-routes-20250806/
      9 - does not order the vertices by distance, just produces the distances
     10   - if you have to order the vertices, [Dijkstra's_algorithm] is optimal
     11     - cf [haeupler2025universal]
