What would you like to share? Implement Dijkstra's algorithm for finding shortest paths from a source vertex to all other vertices in a weighted graph.

When Edsger W. Dijkstra published his algorithm in 1959, computer networks were barely a thing. The algorithm in question found the shortest path between any two nodes on a graph, with a variant ...

The original version of this story appeared in Quanta Magazine. 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 ...

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 ...

Source code for the HappyCoders.eu articles on pathfinding and shortest path algorithms (Dijkstra, A*, Bellman-Ford, Floyd-Warshall). This project simulates real bus transportation systems, analyzes ...

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 ...

This week I interviewed Senator Amy Klobuchar, Democrat of Minnesota, about her Preventing Algorithmic Collusion Act. If you don’t know what algorithmic collusion is, it’s time to get educated, ...

While encrypting information with color images, most encryption schemes treat color images as three different grayscale planes and encrypt each plane individually. These algorithms produce more ...

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 ...
