Breaking the Sorting Barrier for Directed Single-Source Shortest Paths
Overview
Paper Summary
This paper introduces a deterministic algorithm for the single-source shortest path (SSSP) problem on directed graphs with non-negative edge weights. The algorithm achieves a time complexity of O(m log^(2/3) n), improving upon Dijkstra's algorithm for sparse graphs. This is the first deterministic algorithm to break the O(m + n log n) time bound in this setting.
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 for certain types of graphs. It's like finding a quicker route on a map with one-way streets.
