A bound for the Symmetric Travelling Salesman problem through matroid formulation
Article Abstract:
A bound for the Symmetric Traveling Salesman Problem (TSP) is developed. The Symmetric TSP is modeled as a matroid intersection problem with parity conditions. The new model also provides a relaxation of the problem and establishes a link between the well-studied 1-tree and 2-matching bounds. An algorithm to determine the lower bound provided by the relaxation is also discussed.
