A high-performance implementation of Dijkstra's shortest path algorithm comparing sequential and parallel approaches using Intel TBB (Threading Building Blocks). Dijkstra/ ├── main.cpp # Main program ...

There is a new sorting algorithm a deterministic O(m log2/3 n)-time algorithm for single-source shortest paths (SSSP) on directed graphs with real non-negative edge weights in the comparison-addition ...

If you want to solve a tricky problem, it often helps to get organized. You might, for example, break the problem into pieces and tackle the easiest pieces first. But this kind of sorting has a cost.

In the Dijkstra algorithm, when a shorter path to a neighbor is found, the neighbor's priority in the priority queue should be updated regardless of whether it is already present in the queue. In this ...

The original version of this story appeared in Quanta Magazine. If you’ve been making the same commute for a long time, you’ve probably settled on what seems like the best route. But “best” is a ...

Abstract: Dijkstra algorithm is a single-source shortest path algorithm, and the result is the shortest distance from the source node to the destination node. In the parking guidance process, the ...
