32   	 * The inference history branching rule is based on the average number of deductions obtained after
33   	 * branching this variable upwards and downwards.
34   	 * Variables which cause many problem reductions are preferred since they are more likely to drive
35   	 * the created sub-tree towards infeasibility.
36   	 * Inference history of the variables is updated during the branch-and-bound search.
37   	 *
38   	 * For a more detailed description and a comparison between the inference rule and other branching rules
39   	 * in SCIP, we refer to
