I am talking about only edges not the negative weight cycles.周四, 02 4月 2026 11:36:00 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?周五, 03 4月 2026 03:57:00 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).周五, 03 4月 2026 11:21:00 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.周日, 29 3月 2026 17:53:00 GMThttps://stackoverflow.com/questions/61890100/why-is-the-time-complexity-of-dijkstra-ov-e-logvI was reading about worst case time complexity for the Dijkstra algorithm using binary heap (the graph being represented as adjacency list). According to Wikipedia and various stackoverflow questions, this is O((V + E) logV) where E - number of edges, V - number of vertices.周六, 04 4月 2026 04:53:00 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.周一, 30 3月 2026 09:02:00 GMThttps://stackoverflow.com/questions/14038011/dijkstras-algorithm-a-greedy-or-dynamic-programming-algorithmIn this post it is described Dijkstras as a greedy algorithm, while here and here it is shown to have connections with dynamic programming algorithms. Which one is it then?周四, 02 4月 2026 11:15:00 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 ...周三, 01 4月 2026 18:04:00 GMT
