The lazy travelling salesman problem in 2
ESAIM: Control, Optimisation and Calculus of Variations, Tome 13 (2007) no. 3, pp. 538-552.

We study a parameter (σ) dependent relaxation of the Travelling Salesman Problem on 2 . The relaxed problem is reduced to the Travelling Salesman Problem as σ 0. For increasing σ it is also an ordered clustering algorithm for a set of points in 2 . A dual formulation is introduced, which reduces the problem to a convex optimization, provided the minimizer is in the domain of convexity of the relaxed functional. It is shown that this last condition is generically satisfied, provided σ is large enough.
