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. …

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 …

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 …

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 …

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, …

May 7, 2017 · It's stated in a book that "Dijkstra's algorithm only works with Directed Acyclic Graphs". It appears the algorithm works for graphs with cycles too as long as there are no …

Oct 9, 2012 · I was wondering what's the difference between uniform-cost search and Dijkstra's algorithm. They seem to be the same algorithm.

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 …
