The authors show more generally that in any fixed dimension 1 k dand 2 d it is NP hard to minimize the volume ....

....a set of points in the Euclidean plane Area Optimization Problems In the min area TSP (resp. max area TSP) the goal is to determine a cycle on a given set S of points such that the cycle defines a simple polygon of minimum (resp. maximum) area. Fekete [153] in part together with Pulleyblank [155]) has studied these problems extensively. He has shown that both the min area and max area TSP problems are NP complete. For the max area TSP, Fekete gives a (1=2) approximation algorithm, showing how, in O(n log n) time, one can obtain a cycle surrounding area that is at least half that of the ....
