Graphs that are non-Eulerian but are Hamiltonian

WebDefinition: A Hamiltonian cycle is a cycle that contains all vertices in a graph . If a graph has a Hamiltonian cycle, then the graph is said to be Hamiltonian. For example, let's look at the following graphs (some of which were observed in earlier pages) and determine if they're Hamiltonian. Determining if a Graph is Hamiltonian WebJul 17, 2024 · One example of an Euler circuit for this graph is A, E, A, B, C, B, E, C, D, E, F, D, F, A. This is a circuit that travels over every edge once and only once and starts and ends in the same place. There are other Euler circuits for this graph. This is just one example. Figure 6.3. 6: Euler Circuit The degree of each vertex is labeled in red. WebFor example, n = 6 and deg ( v) = 3 for each vertex, so this graph is Hamiltonian by Dirac's theorem.
