The most famous shortest-paths algorithm, devised by the pioneering computer scientist Edsger Dijkstra in 1956, starts at the source and works outward step by step. It’s an effective approach because ...

In this note we present some computational evidence to suggest that a version of Bellman's shortest-path algorithm outperforms Treesort-Dijkstra's for a certain class of networks ...

Unfortunately, prior research does not provide a clear direction for choosing an algorithm when one faces the problem of computing shortest paths on real road networks. Most of the computational ...

The key to the “single-source shortest-paths” or SSSP problem breakthrough is a combination of Dijkstra’s algorithm with the Bellman-Ford algorithm. Photo: Shutterstock ...
