WebMar 21, 2024 · A Graph is a non-linear data structure consisting of vertices and edges. The vertices are sometimes also referred to as nodes and the edges are lines or arcs that connect any two nodes in the graph. More formally a Graph is composed of a set of vertices ( V ) and a set of edges ( E ). The graph is denoted by G (E, V). 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 … simonton window sashhttp://academics.triton.edu/faculty/ebell/6%20-%20graph%20theory%20and%20trees.pdf simonton windows brickmould 600
