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.
