Shortest path algorithms sit at the heart of modern graph theory and many of the systems that move people, data, and goods around the world. After nearly seventy years of relying on the same classic ...

In algorithms, as in life, negativity can be a drag. Consider the problem of finding the shortest path between two points on a graph — a network of nodes connected by links, or edges. Often, these ...

Graph algorithms constitute a pivotal component of modern computational science, underpinning diverse applications ranging from transportation optimisation and telecommunications to social network ...

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 ...

This project implements and compares several variants of Dijkstra’s shortest path algorithm on large, randomly generated weighted graphs. The goal is to understand how different priority queue designs ...

Comparison and analysis of various styles of algorithms that attempts to solve the problem of finding the least-cost/shortest path in a graph. For instance when you use Google maps, what is going on ...
