For a connected and undirected graph , a spanning tree of that graph is a subgraph that is a tree and connects all the vertices together. A single graph can have multiple spanning trees. A Minimum Spanning Tree MST or minimum weight spanning tree for a weighted, connected, undirected graph is a spanning tree having a weight less than or equal to the weight of every other possible spanning tree.

The weight of a spanning tree is the sum of weights given to each edge of the spanning tree. If G V, E is a graph then every spanning tree of graph G consists of V — 1 edges, where V is the number of vertices in the graph and E is the number of edges in the graph.

There may be several minimum spanning trees of the same weight. If all the edge weights of a graph are the same, then every spanning tree of that graph is minimum. Consider a complete graph of three vertices and all the edge weights are the same then there will be three spanning trees which are also minimal of the same path length are possible.

Below is the image to illustrate the same:. For any cut C of the graph, if the weight of an edge E in the cut-set of C is strictly smaller than the weights of all other edges of the cut-set of C , then this edge belongs to all the MSTs of the graph. For any cycle C in the graph, if the weight of an edge E of C is larger than the individual weights of all other edges of C , then this edge cannot belong to an MST. In the above figure, in cycle ABD , edge BD can not be present in any minimal spanning tree because it has the largest weight among all the edges in the cycle.

If each edge has a distinct weight then there will be only one, i. For all the possible spanning trees, the minimum spanning tree must have the minimum weight possible. However, there may exist some more spanning with the same weight that of minimum spanning tree, and those all may also be considered as Minimum Spanning tree.
