Task goals

  • Foundation: Identify whether a given route through a small network visits every vertex exactly once, distinguishing a Hamiltonian path from a Hamiltonian circuit.
  • Proficient: Find and list Hamiltonian circuits in a weighted network and calculate the total weight (cost/distance/time) of a given circuit.
  • Excellence: Determine the optimal (minimum-weight) Hamiltonian circuit for a network using systematic trial or a nearest-neighbour-style strategy, justifying that no shorter circuit exists.
