18  * @author Dieter Weninger
19  *
20  * This presolver looks for dominance relations between variable pairs.
21  * From a dominance relation and certain bound/clique-constellations
22  * variable fixings mostly at the lower bound of the dominated variable can be derived.
23  * Additionally it is possible to improve bounds by predictive bound strengthening.
