Polynomial time reduction examples
WebSo for example we could use a polynomial number of instances of Y and we could do lots of transformations, as long as none of the costs can be exponential in any situation. But we get pretty far just with this simple concept of reduction. Important point about polynomial time reduction is that it's transitive. WebTheorem: Approx-TSP-Tour is a polynomial time 2-approximation algorithm for TSP with triangle inequality. Proof: The algorithm is correct because it produces a Hamiltonian circuit. The algorithm is polynomial time because the most expensive operation is MST-Prim, which can be computed in O(E lg V) (see Topic 17 notes).
