Definition: A path through a graph that starts and ends at the same vertex and includes every other vertex exactly once.
Also known as tour.
Generalization (I am a kind of ...)
Specialization (... is a kind of me.)
See also Hamiltonian path, Euler cycle, vehicle routing problem, perfect matching.
Note: A Hamiltonian cycle includes each vertex once; an Euler cycle includes each edge once.
Also known as a Hamiltonian circuit.
Named for Sir William Rowan Hamilton (1805-1865).
