A single spanning tree of a graph can be found in linear time by either depth-first search or breadth-first search. Both of these algorithms explore the given graph, starting from an arbitrary vertex v, by looping through the neighbors of the vertices they discover and adding each unexplored neighbor to a data structure to be explored later. They differ in whether this data structure is a stack (in the case of depth-first search) or a queue (in the case of breadth-first search). In either … WebThe graph theory can be described as a study of points and lines. Graph theory is a type of subfield that is used to deal with the study of a graph. With the help of pictorial representation, we are able to show the mathematical truth. The relation between the nodes and edges can be shown in the process of graph theory.

WebThe number t(G) of spanning trees of a connected graph is a well-studied invariant.. In specific graphs. In some cases, it is easy to calculate t(G) directly: . If G is itself a tree, then t(G) = 1.; When G is the cycle graph C n with n vertices, then t(G) = n.; For a complete graph with n vertices, Cayley's formula gives the number of spanning trees as n n − 2.
