Description:
The intersection cut paradigm is a powerful framework that facilitates
the generation of valid linear inequalities, or cutting planes, for a potentially complex set S. The key ingredients in this construction are a
simplicial conic relaxation of S and an S-free set: a convex zone whose
interior does not intersect S. Ideally, such S-free set would be maximal
inclusion-wise, as it would generate a deeper cutting plane. However, maximality can be a challenging goal in general. In this work, we show how
to construct maximal S-free sets when S is defined as a general quadratic
inequality. Our maximal S-free sets are such that efficient separation of
a vertex in LP-based approaches to quadratically constrained problems is
guaranteed. To the best of our knowledge, this work is the first to provide
maximal quadratic-free sets.
