Apr 7, 2014 · I am trying to implement Dijkstra's algorithm in python using arrays. This is my implementation.

Oct 31, 2012 · Can somebody tell me why Dijkstra's algorithm for single source shortest path assumes that the edges must be non-negative. I am talking about only edges not the negative …

Apr 21, 2017 · Therefore, dijkstra has the advantage over A* which is that it works for any general graph (with the exception of A* being faster in some cases). It could well be that certain …

Variants of Dijkstra's Algorithm The key is there are 3 kinds of implementation of Dijkstra's algorithm, but all the answers under this question ignore the differences among these variants. …

Oct 23, 2012 · It says A* is faster than using dijkstra and uses best-first-search to speed things up. A* is basically an informed variation of Dijkstra. A* is considered a "best first search" …

May 18, 2010 · I understand what Dijkstra's algorithm is, but I don't understand why it works. When selecting the next vertex to examine, why does Dijkstra's algorithm select the one with …

Dijkstra's algorithm runs on positive weighed graphs, otherwise the priority queue would be useless. In your example, Dijkstra's algorithm would work because the graph is both weighed …

Aug 26, 2009 · Dijkstra's algorithm is definitely complete and optimal that you will always find the shortest path. However it tends to take longer since it is used mainly to detect multiple goal …

May 12, 2010 · I'm working on Dijkstra's algorithm, and I really need to find all the possible shortest paths, not just one. I'm using an adjacency matrix and I applied Dijkstra's algorithm, …

Nov 6, 2012 · Consider the directed graph shown in the figure below. There are multiple shortest paths between vertices S and T. Which one will be reported by Dijstra?s shortest path …
