The computational complexity of the partition problem , which concerns the partitioning of a set of n vectors in d -space into p parts so as to maximize an objective function which is convex on the sum of vectors in each part, is determined by the number of vertices of the corresponding p-partition polytope defined to be the convex hull in d p )-space of all solutions.In this article, introducing and using the class of Momentopes , we establish the lower bound p , d ( n )= Ω( n ( d 1)/2 M p ) on the maximum number of vertices of any p -partition polytope of a set of n points in d -space, which is quite compatible with the recent upper bound p , d ( n )= O ( n d ( p 1) 1, implying the same bound on the complexity of the partition problem. We also discuss related problems on the realizability of Davenport--Schinzel sequences and describe some further properties of Momentopes. |
