Math Problem Statement
Solution
To solve this using the sorted edges algorithm, we aim to construct a Hamiltonian circuit (a tour visiting every vertex exactly once and returning to the start) by selecting edges in order of increasing weight, ensuring no vertex is visited more than once except the starting/ending vertex and avoiding closed loops until the full circuit is formed.
Steps:
-
Sort the edges by weight in ascending order. We list all the edges and their weights:
- : 1
- : 2
- : 6
- : 5
- : 7
- : 12
- : 14
- : 13
Sorted: (1), (2), (6), (5), (7), (12), (13), (14).
-
Add edges without forming loops or revisiting a vertex unless completing the circuit. Following the sorted order:
- (1): Add this edge.
- (2): Add this edge.
- (5): Add this edge.
- (6): Add this edge.
- (7): Add this edge.
At this point, we have: .
-
Finalize the circuit: Ensure the vertices are connected in a full circuit: Final path: .
