algorithm - Bellman-Ford vs Dijkstra: Under what circumstances is ...
76 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 …
What is Sliding Window Algorithm? Examples? - Stack Overflow
While solving a geometry problem, I came across an approach called Sliding Window Algorithm. Couldn't really find any study material/details on it. What is the algorithm about?
The best shortest path algorithm - Stack Overflow
What is the difference between the "Floyd-Warshall algorithm" and "Dijkstra's Algorithm", and which is the best for finding the shortest path in a graph? I need to calculate the shortest path betw...
algorithm - When should I use Kruskal as opposed to Prim (and vice ...
Mar 20, 2019 · I was wondering when one should use Prim's algorithm and when Kruskal's to find the minimum spanning tree? They both have easy logics, same worst cases, and only difference is …
What is the difference between a heuristic and an algorithm?
Feb 25, 2010 · An algorithm is the description of an automated solution to a problem. What the algorithm does is precisely defined. The solution could or could not be the best possible one but you know from …
Is there an efficient algorithm to generate a 2D concave hull?
The answer may still be interesting for somebody else: One may apply a variation of the marching square algorithm, applied (1) within the concave hull, and (2) then on (e.g. 3) different scales that my …
algorithm - Difference and advantages between dijkstra & A star
Oct 23, 2012 · A* is just like Dijkstra, the only difference is that A* tries to look for a better path by using a heuristic function which gives priority to nodes that are supposed to be better than others while …
