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 …

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" …

Jun 27, 2016 · As per my understanding, I have calculated time complexity of Dijkstra Algorithm as big-O notation using adjacency list given below. It didn't come out as it was supposed to …

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. …

Aug 26, 2009 · Dijkstra’s algorithm uses the edge’s weight as a distance function, so we need to pass something like distance = lambda(e) → e.weight BFS only takes into account the number …

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 …

May 23, 2025 · Dijkstra's algorithm and A* are both examples of "best-first" graph searches, where a node is expanded when it is currently the "best" open node, as measured by some …

What is the difference between the "Floyd-Warshall algorithm" and "Dijkstra's Algorithm", and which is the best for finding the shortest path in a graph? I need to calculate the shortest path …

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 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, …
