WebPrim's algorithm to find minimum cost spanning tree (as Kruskal's algorithm) uses the greedy approach. Prim'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 keeps on adding new nodes to the spanning tree from the given graph. WebGreedy Algorithms, Minimum Spanning Trees, and Dynamic Programming. The primary topics in this part of the specialization are: greedy algorithms (scheduling, minimum …

WebGreedy MST Rules All of these greedy rules work: 1 Add edges in increasing weight, skipping those whose addition would create a cycle.
