How does the **Christofides Algorithm** approximate the solution to TSP?
The Christofides algorithm uses a greedy approach to select edges that connect the nodes in the shortest possible way, without checking for cycle creation.
Thatâ€™s partially correct. Christofides uses a greedy approach to build the minimum spanning tree, but the cycle formation and odd-degree matching are also crucial.
Can you explain why forming an Eulerian circuit is necessary in the Christofides algorithm?
