Metric Traveling Salesman Games

The Traveling Salesman game is given by the tuple (N, cD) where N is the set of cities (or the vertices of the complete graph) and cD is a real function defined on all subsets of N where D is the underlying cost matrix, with cD(S) being the cost of a minimum cost Hamiltonian tour through the vertices S and "0" where 0 ∉ N is called as the home city. The core of this game is defined to be the set of all n-dimensional real vectors x, such that x(N) = cD(N) and x(S) <= cD(S) for all subsets S. In this talk, we show that the problem of determining whether the core of a TS game with D satisfying triangle inequality (Metric TS game) is empty or not, is NP-Complete. Further, we define approximate core allocation and show some results pertaining to the Asymmetric TS game.
