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