WebJan 14, 2024 · Then there is also a Hamiltonian path $(x_{i-1}, x_{i-2}, \dots, x_1, x_i, x_{i+1}, \dots, x_n)$ - and in this Hamiltonian path, $\deg(x_{i-1}) + \deg(x_n) \ge n$. Now we can follow the standard proof of Ore's theorem to show that this Hamiltonian path can be turned into a Hamiltonian cycle. WebMar 24, 2024 · A Hamiltonian path, also called a Hamilton path, is a graph path between two vertices of a graph that visits each vertex exactly once. If a Hamiltonian path exists whose endpoints are adjacent, then the resulting graph cycle is called a Hamiltonian cycle (or Hamiltonian cycle).
