Webb6 apr. 2024 · The Hamiltonian path problem and the Hamiltonian cycle problem are problems of determining whether a Hamiltonian path (a path in an undirected or directed graph that visits each vertex exactly once) or a Hamiltonian cycle exists in a given graph (whether directed or undirected). WebbSimple path in graph theory. A simple path is a path where each vertex occurs / is visited only once. Note that in modern graph theory this is also simply referred to as path, order now. Simple path. A path is simple if all of its vertices are distinct.

If every vertex in G has degree at least n/2, then G has a Hamiltonian cycle. In our case, G has 2k+1 vertices, so n=2k+1. Since G is k-regular, each vertex in G has degree k.
