WebAug 30, 2024 · In graph theory, we can use specific types of graphs to model a wide variety of systems in the real world. An undirected graph (left) has edges with no directionality. On the contrary, a directed graph (center) has edges with specific orientations. Finally, a weighted graph (right) has numerical assignments to each edge. WebMar 21, 2024 · A graph G = ( V, E) is said to be hamiltonian if there exists a sequence ( x 1, x 2, …, x n) so that. Such a sequence of vertices is called a hamiltonian cycle. The first graph shown in Figure 5.16 both eulerian and hamiltonian. The second is hamiltonian but not eulerian. Figure 5.16.

In the mathematical discipline of graph theory, the line graph of an undirected graph G is another graph L(G) that represents the adjacencies between edges of G. L(G) is constructed in the following way: for each edge in G, make a vertex in L(G); for every two edges in G that have a vertex in common, make an edge between their corresponding vertices in L(G).
