What is the difference between dijkstra and kruskal

WebThe two most popular algorithms for finding MST (Kruskal's and Prim's) work fine with negative edges. Actually, you can just add a big positive constant to all the edges of your graph, making all the edges positive. The MST (as a subset of edges) will remain the same.

WebPrims algorithm gets you the minimum spaning tree for a given graph. A tree that connects all nodes while the sum of all costs is the minimum possible. Prim’s algorithm stores a minimum cost edge whereas Dijkstra’s algorithm stores the total cost from a source vertex to the current vertex. In computer science, Prim's algorithm (also known as Jarník's algorithm) is a greedy algorithm that finds a minimum spanning tree for a weighted undirected graph. This means it finds a subset of the edges that forms a tree that includes every vertex, where the total weight of all the edges in the tree is minimized. The algorithm operates by building this tree one vertex at a time, from an arbitrary starting vertex, at each step adding the cheapest possible connection from the tree to another v…
