In graph theory, a Hamiltonian cycle is a cycle that visits each vertex exactly once. This question has a long history, and I have followed some articles. But what I want to ask is: - Is there a monograph or review of the Hamiltonian Cycles of graphs (or long cycles)? I've been looking for a long time, but I haven't seen some in-depth, systematic monographs. We can find plenty of examples of Hamiltonian cycles by using google scholar. - S.
