Direction assignment has been shown to improve the synchronizability of undirected networks in general, but we find that in some cases incommunicable components emerge and networks fail to synchronize. We show that the REBG method can effectively avoid the synchronization failure ($R=\\lambda_{2}^{r}/\\lambda_{N}^{r}=0$) which occurs in the residual degree gradient (RDG) method proposed in Phys.
