Graph theory tree

In graph theory, a tree is an undirected graph in which any two vertices are connected by exactly one path, or equivalently a connected acyclic undirected graph.

The complete graph with n graph vertices is denoted K_n and has (n; 2)=n(n-1)/2 (the triangular numbers) undirected edges, where (n; k) is a binomial coefficient. In older literature, complete graphs are sometimes called universal graphs. …

WebThe only difference is the word 'spanning', a kind of 'skeleton' which is just capable to hold the structure of the given graph G. Infact, there may be more than one such 'skeletons' in a given graph but a tree T has the only one i.e. T itself.

In the mathematical field of graph theory, a spanning tree T of an undirected graph G is a subgraph that is a tree which includes all of the vertices of G. In general, a graph may have several spanning trees, but a graph that is not connected will not contain a spanning tree (see about spanning forests below). If all of the edges of G are also edges of a spanning tree T of G, then G is a tree … WebGraph Theory and Trees Graphs A graph is a set of nodes which represent objects or operations, and vertices which represent links between the nodes.
