What is the difference between path and circuit? Define Hamiltonian path and circuit.

Answer

Paths do not repeat vertices/edges; circuits are closed paths. Hamiltonian visits every vertex.

  • Path: A sequence of edges where no vertex (and thus no edge) is repeated.
  • Circuit: A closed path (starts and ends at the same vertex).
  • Hamiltonian Path: A path that visits every vertex in the graph exactly once.
  • Hamiltonian Circuit: A circuit that visits every vertex exactly once and returns to the start.
