27 * @brief dominated column presolver
28 * @author Dieter Weninger
29 *
30 * This presolver looks for dominance relations between variable pairs.
31 * From a dominance relation and certain bound/clique-constellations
32 * variable fixings mostly at the lower bound of the dominated variable can be derived.
33 * Additionally it is possible to improve bounds by predictive bound strengthening.
