Source

    cons: *mut SCIP_CONS,
    deltaage: f64,
) -> SCIP_RETCODE
Expand description

adds given value to age of constraint, but age can never become negative; should be called

  • in constraint separation, if no cut was found for this constraint,
  • in constraint enforcing, if constraint was feasible, and
  • in constraint propagation, if no domain reduction was deduced;

@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_TRANSFORMED - \ref SCIP_STAGE_PRESOLVING - \ref SCIP_STAGE_PRESOLVED - \ref SCIP_STAGE_SOLVING - \ref SCIP_STAGE_SOLVED
