| Popis | We prove that a graph G of order n has a hamiltonian prism if and only if the graph Cl4n/3-4/3(G) has a hamiltonian prism where Cl4n/3-4/3(G) is the graph obtained from G by sequential adding edges between non-adjacent vertices whose degree sum is at least 4n/3 - 4/3. We show that this cannot be improved to less than 4n/3 - 5. (c) 2006 Wiley Periodicals, Inc. |
