31 *
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
