Shortest Path Algorithms

Radio Shortest Path First (RSPF) is a routing protocol for wireless networks. This particular implementation is written for Linux and conforms to version 2.2 of the protocol specification. There are many reasons why our networks are complicated, but one significant thing is that you can no longer...

How do you find the shortest path from one point to another in a computationally efficient way? The A* algorithm provides one implementation where the distance to the goal is considered as a heuristic in addition to local weightings, and the best path is recovered without combinatorial complexity.

The Floyd-Warshall algorithm computes the all pairs shortest path matrix for a given adjacency matrix. The algorithm is O(n^3), and in most implementations you will see 3 nested for loops. This is very inefficient in Matlab, so in this version the two inner loops are vectorized (and as a result,...
