13 déc 2014 · Dijkstra's algorithm is a graph searching algorithm which is used to find shortest path from source node to all the remaining nodes As far as |
Answer: The main limitation of Dijkstra's algorithm is that it does not work correctly with graphs that have negative edge weights.
In fact, if there are negative weights in a graph, Dijkstra's algorithm can give incorrect results or even go into an infinite loop.
What is Dijkstra's algorithm briefly explain?
Dijkstra's algorithm (/ˈdaɪkstrəz/ DYKE-strəz) is an algorithm for finding the shortest paths between nodes in a weighted graph, which may represent, for example, road networks.
It was conceived by computer scientist Edsger W.
Dijkstra in 1956 and published three years later.
What is Dijkstra's algorithm PDF?
Dijkstra) solves the problem of finding the shortest path from a point in a graph (the source) to a destination.
It turns out that one can find the shortest paths from a given source to all points in a graph in the same time, hence this problem is sometimes called the single-source shortest paths problem.31 jan. 2024
