Source 
pub unsafe extern "C" fn SCIPupdateLocalLowerbound(
    scip: *mut SCIP,
    newbound: f64,
) -> SCIP_RETCODE
Expand description

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

@note the given new bound has to be a lower bound, i.e., it has to be valid for the transformed problem.

@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_PRESOLVING - \ref SCIP_STAGE_PRESOLVED - \ref SCIP_STAGE_SOLVING
