fullstrong branching on fractional and multi-aggregated variables
This branching rule uses all fractional binary and integer variables as candidates, as well as fractional multiaggregated binary and integer variables. Although not directly contained in the presolved problem anymore, the multi-aggregation provides an affine linear sum of integer variables, on which branching can be performed.
