Theorem 13.2.1. If G is a graph with a Hamilton cycle, then for every S ⊂ V with S ≠ ∅, V, the graph G ∖ S has at most | S | connected components. Proof. Example 13.2.1. When a non-leaf is deleted from a path of length at least 2, the deletion of this single vertex leaves two connected components.

The density is the ratio of edges present in a graph divided by the maximum possible edges. In the case of a complete directed or undirected graph, it already has the maximum number of edges, and we can’t add any more edges to it. Hence, the density will be . Additionally, it also indicates the graph is fully dense. A graph with all isolated ...I can see why you would think that. For n=5 (say a,b,c,d,e) there are in fact n! unique permutations of those letters. However, the number of cycles of a graph is different from the number of permutations in a string, because …Definition. In formal terms, a directed graph is an ordered pair G = (V, A) where [1] V is a set whose elements are called vertices, nodes, or points; A is a set of ordered pairs of vertices, called arcs, directed edges (sometimes simply edges with the corresponding set named E instead of A ), arrows, or directed lines. As the names indicate sparse graphs are sparsely connected (eg: Trees). Usually the number of edges is in O (n) where n is the number of vertices. Therefore adjacency lists are preferred since they require constant space for every edge. Dense graphs are densely connected. Here number of edges is usually O (n^2).An edge-colored graph (G, c) on n ≥ 3 vertices is called properly vertex-pancyclic if each vertex of (G, c) is contained in a proper cycle of length ℓ for every ℓ with 3 ≤ ℓ ≤ n.
