Graph trees
A connected acyclic graphis called a tree. In other words, a connected graph with no cycles is called a tree. The edges of a tree are known as branches. Elements of trees are called their nodes. The nodes without child nodes are called leaf nodes. A tree with ‘n’ vertices has ‘n-1’ edges. If it has one more edge extra than … See more A disconnected acyclic graphis called a forest. In other words, a disjoint collection of trees is called a forest. Example The following graph looks … See more Let ‘G’ be a connected graph with ‘n’ vertices and ‘m’ edges. A spanning tree ‘T’ of G contains (n-1) edges. Therefore, the number of edges you need to delete from ‘G’ in order to get a … See more Let G be a connected graph, then the sub-graph H of G is called a spanning tree of G if − 1. H is a tree 2. H contains all vertices of G. A spanning tree … See more Kirchoff’s theorem is useful in finding the number of spanning trees that can be formed from a connected graph. Example The matrix ‘A’ be filled as, if there is an edge between two … See more Web4 Graph Theory III Definition. A tree T = (V,E) is a spanning tree for a graph G = (V0,E0) if V = V0 and E ⊆ E0. The following figure shows a spanning tree T inside of a graph G. = T Spanning trees are interesting because they connect all the nodes of a graph using the smallest possible number of edges.
