This is my implementation.Thu, 09 Apr 2026 12:25:00 GMThttps://stackoverflow.com/questions/26547816/understanding-time-complexity-calculation-for-dijkstra-algorithmAs 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 that led me to unde...Wed, 08 Apr 2026 05:10:00 GMThttps://stackoverflow.com/questions/13159337/why-doesnt-dijkstras-algorithm-work-for-negative-weight-edgesCan 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 weight cycles.Thu, 09 Apr 2026 03:14:00 GMThttps://stackoverflow.com/questions/6799172/negative-weights-using-dijkstras-algorithmVariants 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. Using a nested for -loop to relax vertices. This is the easiest way to implement Dijkstra's algorithm. The time complexity is O (V^2).Tue, 07 Apr 2026 20:20:00 GMThttps://stackoverflow.com/questions/1332466/how-does-dijkstras-algorithm-and-a-star-compareDijkstra'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 nodes.Tue, 07 Apr 2026 10:19:00 GMThttps://stackoverflow.com/questions/3743843/does-dijkstras-algorithm-relax-the-edges-of-the-shortest-path-in-orderHe 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 applies to every vertex reachable from the source.Mon, 06 Apr 2026 18:27:00 GMThttps://stackoverflow.com/questions/14144279/difference-between-prims-and-dijkstras-algorithmsWhat is the exact difference between Dijkstra's and Prim's algorithms? I know Prim's will give a MST but the tree generated by Dijkstra will also be a MST. Then what is the exact difference?Wed, 08 Apr 2026 15:47:00 GMThttps://stackoverflow.com/questions/1909281/use-dijkstras-to-find-a-minimum-spanning-treeA: 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. Clearly, the predecessor subgraph that is produced is a spanning tree of G, but is the sum of edge weights minimized?Fri, 10 Apr 2026 00:07:00 GMThttps://stackoverflow.com/questions/19482317/bellman-ford-vs-dijkstra-under-what-circumstances-is-bellman-ford-better76 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 algorithm better than the Dijkstra algorithm? I know "better" is a broad statement, so specifically I mean in terms of speed and also space if that applies.Wed, 08 Apr 2026 13:02:00 GMThttps://stackoverflow.com/questions/13031462/difference-and-advantages-between-dijkstra-a-starIt 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" because it greedily chooses which vertex to explore next, according to the value of f(v) [f(v) = h(v) + g(v)] - where h is the heuristic and g is the cost so far. Note that if you use a non informative heuristic ...Wed, 08 Apr 2026 13:09:00 GMT
