To construct the Hamiltonian circuit using the nearest neighbor algorithm as directed in the image, starting from the vertex on the far right, we would follow these steps:

Steps Using the Nearest Neighbor Algorithm:

1. Choose the Starting Vertex: Begin at the vertex on the far right (vertex labeled with the number 10).
2. Find the Nearest Neighbor: At each step, move to the closest vertex that hasn’t been visited yet. If there are multiple options with the same distance, choose any of them.
3. Continue Until All Vertices are Visited: Keep selecting the nearest vertex that hasn’t been visited until all vertices are visited exactly once.
4. Return to the Starting Point: Once all vertices are visited, return to the starting point to complete the circuit.

Example Path:

Following this algorithm step-by-step from vertex 10:

• Start at vertex 10.
• Move to the nearest neighbor, say 12.
• From 12, the closest vertex could be 2.
• Continue this process until all vertices are visited.
• Finally, return to 10 to complete the Hamiltonian circuit.
