Abstract

We introduce a new method for solving systems of linear inequalities over the rationals—the conflict resolution method. The method successively refines an initial assignment with the help of newly derived constraints until either the assignment becomes a solution of the system or a trivially unsatisfiable constraint is derived. We show that this method is correct and terminating. Our experimental results show that conflict resolution outperforms the Fourier-Motzkin method and the Chernikov algorithm, in some cases by orders of magnitude.
