We study the relation between a class of 0-1 integer linear programs and their rational relaxations. We show that the rational optimum to a problem instance can be used to construct a provably good 0-1 solution by means of a randomized algorithm. Our technique can be extended to provide bounds on the disparity between the rational and 0-1 optima for a given problem instance.
