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 ...

I would like to contribute implementations of the Bellman-Ford algorithm in Java, along with related LeetCode problems and Cyclic Redundancy Check (CRC) code ...

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 ...

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.

Dijkstra’s algorithm is great as long as we have no negative weight edges in our graph. But there are many problems for which it is natural to represent weights with positive and negative values—gains ...

A program implementing the three shortest paths algorithms for directed weighted graphs which are Dijkstra, Bellman-Ford and Floyd-Warshall.

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 ...
