Wheel Facets of the OLS Polytope

G. Appa, D. Magos, I. Mourtos


Wheel structures of the Orthogonal Latin Squares (OLS) polytope (PI ) are presented in [2]. The current work focuses on the families of valid inequalities arising from wheels and proves that certain among them are facet-defining for PI . For two of these families we provide efficient separation procedures. We also present results regarding odd-hole inequalities, which essentially form a larger class encompassing that of wheel inequalities.
