And a question lead me to think, how to determine if a shortest-path is unique (I want to know is a min-cut is unique).<BR><BR>This is standard Dijkstra stuff, undirected weighted graph (all edges ...

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 ...

Why do you want to base this on Dijkstra's algorithm, which is designed to find a single shortest-path ... number of vertices + edges in the graph) many paths between two vertices (even in ...

If you had a universally optimal algorithm for the simpler problem of just getting from one point on a graph to another, it could help you beat rush hour traffic in every city in the world. Finally, a ...

However, most of distributed and parallel graph algorithms in the MPC model ... However, there are no existing dynamic all-pairs shortest paths (APSP) algorithms working in the MPC model.
