This algorithm delves into some of the most important primitives in graph algorithms: iterative convergence to solutions, graph partitioning, and multi-source shortest path structures. On each of ...

Bellman-Ford algorithm So what do we do when we have negative weights? As long as there are no negative cycles in our weighted directed graph we can use the Bellman-Ford algorithm. Like Dijkstra’s ...

Java Code for Contraction Hierarchies Algorithm, A-Star Algorithm and Bidirectional Dijkstra Algorithm. Tested and Verified Code. The Vehicle Monitoring And Routing System (VMARS) makes use of GPS to ...

I've written a simple Java implementation of Dijkstra's algorithm and A* search for path planning, along with a Matlab interface to the code. The Java planning code is much faster than the same thing ...

In such cases, the fastest known shortest-path algorithm doesn’t work. For decades, fast algorithms for finding shortest paths on negative-weight graphs have remained elusive.
