F. Aykut Özsoy(fozsoyulb.ac.be) Abstract: We consider the problem of clustering a set of items into subsets whose sizes are bounded from above and below. We formulate the problem as a graph partitioning problem and propose an integer programming model for solving it. This formulation generalizes several wellknown graph partitioning problems from the literature like the clique partitioning problem, the equipartition problem and the kway equipartition problem. In this paper, we analyze the structure of the corresponding polytope and prove several results concerning the facial structure. Our analysis yields important results for the closely related equipartition and kway equipartition polytopes as well.
