Finding the Sink Takes Some Time: An Almost Quadratic Lower Bound for Finding the Sink of Unique Sink Oriented Cubes
We give a worst-case Ω( n 2 log n ) lower bound on the number of vertex evaluations a deterministic algorithm needs to perform in order to find the (unique) sink of a unique sink oriented n-dimensional cube. We consider the problem in the vertex-oracle model, introduced in [17]. In this model one can access the orientation implicitly, in each vertex evaluation an oracle discloses the orientatio...
متن کاملUnique Sink Orientations of Cubes
Suppose we are given (the edge graph of) an dimensional hypercube with its edges oriented so that every face has a unique sink. Such an orientation is called a unique sink orientation, and we are interested in finding the unique sink of the whole cube, when the orientation is given implicitly. The basic operation available is the socalled vertex evaluation, where we can access an arbitrary vert...
متن کاملUnique Sink Orientations of Cubes
Subject of this thesis is the theory of unique sink orientations of cubes. Such orientations are suitable to model problems from different areas of combinatorial optimization. In particular, unique sink orientations are closely related to the running time of the simplex algorithm. In the following, we try to answer three main questions: How can optimization problems be translated into the frame...
متن کاملA Linear Algorithm for Finding the Sink of Unique Sink Orientations on Grids
An orientation of a grid is called unique sink orientation (USO) if each of its nonempty subgrids has a unique sink. Particularly, the original grid itself has a unique global sink. In this work we investigate the problem of how to find the global sink using minimum number of queries to an oracle. There are two different oracle models: the vertex query model where the orientation of all edges i...
متن کاملPseudo Unique Sink Orientations
A unique sink orientation (USO) is an orientation of the n-dimensional cube graph (n-cube) such that every face (subcube) has a unique sink. The number of unique sink orientations is nΘ(2 n) [13]. If a cube orientation is not a USO, it contains a pseudo unique sink orientation (PUSO): an orientation of some subcube such that every proper face of it has a unique sink, but the subcube itself hasn...
