- Tsinghua University researchers developed a new algorithm faster than Dijkstra's, breaking a 65-year-old barrier.
- Dijkstra's algorithm, introduced in 1956, was the gold standard for solving the single-source shortest path (SSSP) problem.
- The new algorithm bypasses full sorting by grouping nodes into clusters and using partial ordering, achieving O(m · log^(2/3) n) runtime.
- Applications include faster navigation, optimized network routing, smarter AI, and large-scale graph analytics.
- The algorithm is more complex and slower on small graphs, making Dijkstra's still preferable for everyday systems.
- This breakthrough opens new research avenues in graph theory, AI planning, and big data systems.
