Webb178 CHAPTER 4. SIGNED GRAPHS An example of a balanced graph is shown in Figure 4.1 on the left, in which positive edges are colored green and negative edges are colored red. This graph admits the partition ({v 1,v 2,v 4,v 7,v 8},{v 3,v 5,v 6,v 9}). On the other hand, the graph shown on the right con-tains the cycle (v 2,v 3,v 6,v 5,v 4,v 2 1 4 ...
