Hamiltonian cycle

(definition)

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 ...)
cycle.

Specialization (... is a kind of me.)
traveling salesman.

See also Hamiltonian path, Euler cycle, vehicle routing problem, perfect matching.

Note: Named for Sir William Rowan Hamilton (1805-1865) (a longer biography). A Hamiltonian cycle includes each vertex once; an Euler cycle includes each edge once.

Also known as a Hamiltonian circuit.
