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 …

Apr 7, 2014 · Your code is really confusing: there are 2 different variables named G, unused variable S, and so on. I guess your code just finds ways with no more than 2 edges, as you …

Mar 14, 2017 · A: Dijkstra's Algorithm at every step greedily selects the next edge that is closest to some source vertex s. It does this until s is connected to every other vertex in the graph. …

May 20, 2012 · Finding the shortest route using Dijkstra algorithm Asked 13 years, 5 months ago Modified 1 year, 8 months ago Viewed 33k times

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. …

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 …

Apr 17, 2010 · I was trying to understand this implementation in C of the Dijkstra algorithm and at the same time modify it so that only the shortest path between 2 specific nodes (source and …

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, …

76 After a lot of Googling, I've found that most sources say that the Dijkstra algorithm is "more efficient" than the Bellman-Ford algorithm. But under what circumstances is the Bellman-Ford …
