Consider a convex relaxation ^f of a pseudo-boolean function f. We say that the relaxation is totally half-integral if ^f(x) is a polyhedral function with halfintegral extreme poi...
We study the problem of approximating pseudoBoolean functions by linear pseudo-Boolean functions. Pseudo-Boolean functions generalize ordinary Boolean functions by allowing the fu...
