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 …

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. …

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 …

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

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 …

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" …

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 …

Jan 22, 2018 · 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, …

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 …

Oct 4, 2015 · He claims that Dijkstra's algorithm relaxes the edges of every shortest path in the graph in the order in which they appear on the path, and therefore the path-relaxation property …
