Breaking the Sorting Barrier for Directed Single-Source Shortest Paths
Overview
Paper Summary
The paper introduces a faster deterministic algorithm for the single-source shortest path (SSSP) problem in directed graphs with non-negative edge weights. Using a recursive partitioning technique, the algorithm achieves a time complexity that outperforms Dijkstra's algorithm on sparse graphs. The algorithm assumes constant in-degrees and out-degrees but proposes a transformation for general graphs.
Explain Like I'm Five
This paper presents a faster way to find the shortest path in a directed graph, improving upon the classic Dijkstra's algorithm. It's like finding the quickest route on a map with one-way streets, but doing it more efficiently.
