WebPrim's Algorithm, which is known to produce a minimum spanning tree, is highly similar to Dijkstra's Algorithm, but at each stage it greedily selects the next edge that is closest to any vertex currently in the working MST at that stage. Let's use this observation to produce a counterexample. 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 … cleveland ohio vba
