The reasonable orientation problem of 2-edge connected graph |
| |
| Abstract: | The reasonable orientation of a graph focuses on the passing capacity balance of all the bonds.Because not all graphs have reasonable orientation, a necessary and sufficient condition is given to determine which type of graph can have reasonable orientation and which cann't.In the end,the reasonable orientation is compared with the common orientation which takes the connectivity as its measure. |
