Title:Relaxations for binary polynomial optimization via signed certificates

Abstract:We consider the problem of minimizing a polynomial $f$ over the binary hypercube. We show that, for a specific set of polynomials, their binary non-negativity can be checked in a polynomial time via minimum cut algorithms, and we construct a linear programming representation for this set through the min-cut-max-flow duality. We categorize binary polynomials based on their signed support patterns and develop parameterized linear programming representations of binary non-negative polynomials. This allows for constructing binary non-negative signed certificates with adjustable signed support patterns and representation complexities, and we propose a method for minimizing $f$ by decomposing it into signed certificates. This method yields new hierarchies of linear programming relaxations for binary polynomial optimization. Moreover, since our decomposition only depends on the support of $f$, the new hierarchies are sparsity-preserving.
