Hamiltonian path
Noun
Meaning
Hamiltonian path (plural Hamiltonian paths)
(graph theory) A path through a graph which visits each vertex exactly once.
Examples
The "compulsory" edges of the fragments, that must be part of any Hamiltonian path through the fragment, are connected at the central vertex; because any cycle can use only two of these three edges, there can be no Hamiltonian cycle.
