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

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. …

Nov 10, 2020 · I'm learning the Dijkstra algorithm and I am testing out this code from GeeksforGeeks. I want the program to print the path for the shortest distance between 2 nodes …

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 and …

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 …

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, and I can …

Nov 6, 2011 · The Dijkstra algorithm finds the shortest path in a graph. So if you want to modify this algorithm to find the longest path in a graph, then you just have to multiply the edge weight …

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 …

Mar 29, 2022 · Below is my implementation for Dijkstra's algorithm using heaps (for undirected graphs). This works just fine for reasonably sized graphs however I am not satisfied by my …
