Source code for the HappyCoders.eu articles on pathfinding and shortest path algorithms (Dijkstra, A*, Bellman-Ford, Floyd-Warshall).

Abstract: In this paper we address the problem of optimal routing in shortest-path data networks — such as Internet protocol (IP) networks — using open shortest path first (OSPF), routing information ...

One of the most significant problems in graph theory is finding the shortest path between nodes, which has led to extensive research on efficient algorithms for pathfinding and related queries.

As long as there are no negative cycles in our weighted directed graph we can use the Bellman-Ford algorithm. Like Dijkstra’s algorithm, it takes a graph, G, and some starting node S, and returns the ...
