Witryna21 gru 2024 · Kruskal’s Algorithm is implemented to create an MST from an undirected, weighted, and connected graph. The edges are sorted in ascending order of weights and added one by one till all the vertices are included in it. It is a Greedy Algorithm as the edges are chosen in increasing order of weights. No cycle is created in this algorithm. WitrynaAs discussed earlier, Breadth-First Search (BFS) is an algorithm used for traversing graphs or trees. Traversing means visiting each node of the graph.
