WebA spanning tree of an undirected graph is a subgraph that’s a tree and includes all vertices. A graph G has a spanning tree iff it is connected: If G has a spanning tree, it’s connected: any two vertices have a path between them in the spanning tree and hence in G. If G is connected, we will construct a spanning tree, below. Let G be a ... WebGeneral Trees. A graph which has no cycle is called an acyclic graph. A tree is an acyclic graph or graph having no cycles. A tree or general trees is defined as a non-empty finite set of elements called vertices or nodes having the property that each node can have minimum degree 1 and maximum degree n.
