LetQddenote the graph of thed-dimensional cube. Aunique-sink orientation(USO) is an orientation ofQdsuch that every face ofQnhas exactly one sink (vertex of out degree 0); it does not have to be acyclic. USO have been studied as an abstract model for many geometric optimization problems, such as linear programming, finding the smallest enclosing ball of a given point set, certain classes of convex programming, and certain linear complementarity problems. It is shown that the number of USO is.
