Expand description

calculates a strong CG cut out of the weighted sum of LP rows given by an aggregation row; the aggregation row must not contain non-zero weights for modifiable rows, because these rows cannot participate in a strongcg cut

@return \ref SCIP_OKAY is returned if everything worked. Otherwise a suitable error code is passed. See \ref SCIP_Retcode “SCIP_RETCODE” for a complete list of error codes.

@pre This method can be called if @p scip is in one of the following stages: - \ref SCIP_STAGE_SOLVING

See \ref SCIP_Stage “SCIP_STAGE” for a complete list of all possible solving stages.
