Expand description

if given value is higher than the node’s lower bound (in transformed problem), sets the node’s lower bound to the new value.

@note must not be used on a leaf because the node priority queue remains untouched

@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 in one of the following stages of the SCIP solving process: - \ref SCIP_STAGE_SOLVING
