Hierarchies of semidefinite relaxations for 0/1 polytopes have been constructed by Lasserre (2001a) and by LovAisz and Schrijver (1991). The cut polytope of a graph onn nodes can be expressed as a projection of such a semidefinite relaxation after at mostn steps. We show that [ n/2] iterations are needed for finding the cut polytope of the complete graphK n .
