30   	 *
31   	 * This branching rule uses all fractional binary and integer variables as candidates,
32   	 * as well as fractional multiaggregated binary and integer variables. Although not
33   	 * directly contained in the presolved problem anymore, the multi-aggregation provides
34   	 * an affine linear sum of integer variables, on which branching can be performed.
35   	 *
36   	 * For more details, see
