Minimum Spanning Tree Algorithms Definition:- A tree is a  connected  graph  without cycles . Properties of Trees ° A graph is a tree if and only if there is  one and only one path  joining any two of its vertices. ° A  connected  graph is a tree if and only if every one of its edges is a  bridge . ° A  connected  graph is a tree if and only if it has  N  vertices and  N; 1 edges . Definitions:- ° A  subgraph  that  spans  (reaches out to )  all  vertices of a graph is called a  spanning subgraph . ° A subgraph that is  a tree and that spans  (reaches out to ) all vertices of the original graph is called a  spanning tree . ° Among all the spanning trees of a weighted and connected graph, the one (possibly more) with the least total weight is called a  minimum spanning tree (MST) . Kruskal's Algorithm Step 1 Find the cheapest edge in the grap...
