We go over Prim's Algorithm, and how it works to find minimum spanning trees (also called minimum weight spanning trees or minimum cost spanning trees). We'll also see two examples of using Prim's algorithm to find minimum spanning trees in connected weighted graphs.

This algorithm is one way to solve the problem of finding a spanning tree of minimum weight in a connected weighted graph. The weight of a subgraph of a weighted graph is the sum of the weights of the subgraph's edges. So, among all spanning trees of a graph G, if we use Prim's algorithm to find a minimum spanning tree T of G, it will be a spanning tree of minimum weight/minimum cost. Note that neither spanning trees nor minimum spanning trees are necessarily unique.
