A canonical problem in computer science is to find the shortest route to every point in a network. A new approach beats the classic algorithm taught in textbooks.

Bellman-Ford algorithm So what do we do when we have negative weights? As long as there are no negative cycles in our weighted directed graph we can use the Bellman-Ford algorithm. Like Dijkstra’s ...

Computer science pioneer Edsger Dijkstra’s algorithms form the backbone of many computer subroutines, thanks to their elegant efficiency. However, seemingly subtle changes in requirements can lead to ...

For decades, computer scientists working on negative-weight graphs tried to match the speed of Dijkstra’s algorithm with similar “combinatorial” algorithms. These involve discrete operations — like ...

This article introduces the problem of parallelization of Dijkstra's algorithm, a well known algorithm for computing single-source shortest path in a graph. Dijkstra's algorithm can be applied to ...

The classical Dijkstra’s algorithm has been widely used in shortest path problems. It is indeed one of the most referenced shortest path algorithms. However, it is observed that in certain ...

This project solves the problem of transporting heavy loads between cities by finding viable paths through viaducts with height restrictions, using a modified Dijkstra's algorithm for optimal routing.
