Abstract
The problem of integer recognition is to determine whether the maximum of a linear objective function achieved at an integral vertex of a polytope. We consider integer recognition over polytope SATP and its LP relaxation \(SATP_{LP}\). These polytopes are natural extensions of the well-known Boolean quadric polytope BQP and its rooted semimetric relaxation \(BQP_{LP}\).
Integer recognition over \(SATP_{LP}\) is NP-complete, since various special instances of 3-SAT problem like NAE-3SAT and X3SAT are transformed to it. We describe polynomially solvable subproblems of integer recognition over \(SATP_{LP}\) with constrained objective functions. Based on that, we solve some cases of edge constrained bipartite graph coloring.
