In this paper we tackle the problem of ranking the vertices in an undirected graph given some preference relation. We view the preferences as a preorder and aim at finding a linear order which conforms best with the undirected graph while at the same time violating as few as possible preference constraints. This problem has been tackled before using spectral relaxations. For many other problems, including combinatorial optimisation problems as well as clustering and classification problems, it has been observed that semidefinite relaxations offer several advantages over spectral ones. To solve ranking problems using semidefinite programming, we incorporate the preferences by enforcing certain angles between the embedding of the vertices. Th...
