Detailed Description

inference history branching rule

Author

The inference history branching rule is based on the average number of deductions obtained after branching this variable upwards and downwards. Variables which cause many problem reductions are preferred since they are more likely to drive the created sub-tree towards infeasibility. Inference history of the variables is updated during the branch-and-bound search.

For a more detailed description and a comparison between the inference rule and other branching rules in SCIP, we refer to
