Abstract
Following the seminal work of Padberg on the Boolean quadric polytope BQP and its LP relaxation \(BQP_{LP}\), we consider a natural extension: the polytopes SATP and \(SATP_{LP}\), with \(BQP_{LP}\) being a projection of \(SATP_{LP}\) face (and BQP – projection of SATP face). Various special instances of 3-SAT problem like NAE-3-SAT, 1-in-3-SAT, weighted MAX-3-SAT, and others can be solved by integer programming over \(SATP_{LP}\). We consider the properties of SATP 1-skeleton and \(SATP_{LP}\) fractional vertices. Like \(BQP_{LP}\), the polytope \(SATP_{LP}\) has the Trubin-property being quasi-integral (1-skeleton of SATP is a subset of 1-skeleton of \(SATP_{LP}\)). However, unlike BQP, not all vertices of SATP are pairwise adjacent, the diameter of SATP equals 2, and the clique number of 1-skeleton is superpolynomial in dimension. It is known that the fractional vertices of \(BQP_{LP}\) are half-integral (0, 1 or 1/2 valued). We establish that the denominators of \(SATP_{LP}\) fractional vertices can take any integer values.
