WebOverview. Kruskal's algorithm is a greedy algorithm in graph theory that is used to find the Minimum spanning tree (A subgraph of a graph G (V, E) G(V,E) G (V, E) which is a tree and includes all the vertices of the given graph such that the sum of the weight of the edges is minimum) of a given connected, weighted, undirected graph. In case, the graph is not … megan pope facebook

WebPrim's algorithm is a greedy algorithm. It 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 ... WebExplanation: Kruskal’s algorithm is a greedy algorithm to construct the MST of the given graph. It constructs the MST by selecting edges in increasing order of their weights and …
