How does the Prim algorithm work?
- The Prim algorithm, essentially, works by creating two components of the graph at each iteration and finding the minimum cost edge between them, knowing that such an edge has to be in the MST. This ensures that all the edges added using Prim's algorithm are edges of a valid MST of the graph.

What are the similarities between prim's and Kruskal's algorithms?
- First, the similarities: Prim’s and Kruskal’s algorithms both find the minimum spanning tree in a weighted, undirected graph. They are both considered greedy algorithms, because at each they add the smallest edge from a given set of edges. The best implementations of each also have the same big O time complexity: O ( E log ( V)).
How to prove Prim's algorithm correctly finds an MSt in G?
- Theorem:If Gis a connected, weighted graph, Prim's algorithm correctly finds an MST in G. Proof:Let Tbe the spanning tree found by Prim's algorithm and T*be any MST of G. We will prove c(T) = c(T*). If T= T*, then c(T) = c(T*) and we are done. Otherwise, T ? T*, so we have T– T*? Ø. Let (u, v) be any edge in T– T*.
