## Abstract:

We consider the special case of the traveling salesman problem (TSP)
in which the distance metric is the shortest-path metric of a planar
unweighted graph. We sketch a polynomial-time approximation scheme
(PTAS) for this problem, and propose some open problems for extending
the result to more general metrics.
