In the Travelling Salesman Problem (TSP), we are given a complete graph K n together with an integer weighting w on the edges of K n , and we are asked to find a Hamilton cycle of K n of minimum weight. Let h(w) denote the average weight of a Hamilton cycle of K n for the weighting w. Vizing (1973) asked whether there is a polynomialtime algorithm which always finds a Hamilton cycle of weight at most h(w). He answered this question in the affirmative and subsequently Rublineckii (1973) and others described several other TSP heuristics satisfying this property. In this paper, we prove a considerable generalisation of Vizing's result: for each fixed k, we give an algorithm that decides whether, for any input edge weighting w of K n , there is a Hamilton cycle of K n of weight at most h(w) − k (and constructs such a cycle if it exists). For k fixed, the running time of the algorithm is polynomial in n, where the degree of the polynomial does not depend on k (i.e., the generalised Vizing problem is fixed-parameter tractable with respect to the parameter k).
