WebPrim's algorithm is another popular minimum spanning tree algorithm that uses a different logic to find the MST of a graph. Instead of starting from an edge, Prim's algorithm starts from a vertex and keeps adding lowest-weight edges which aren't in the tree, until all vertices have been covered. Kruskal's Algorithm Complexity WebPrim's algorithm shares a similarity with the shortest path first algorithms. Prim's algorithm, in contrast with Kruskal's algorithm, treats the nodes as a single tree and …
