(20 points) Consider the following graph with 6 square-shaped vertices and 7 undirected edges. In this problem, you can color each edge using one color from the following set of 3 colors (Red, Green, Blue}, and you are asked to solve this edge-coloring problem as a constraint satisfaction problem. In this "edge-coloring" problem, no two adjacent edges have the same color. For example, El and E2 cannot have the same color because both are adjacent at the vertex V4. On the other hand, it is possible that E2 and E4 have the same color because they are not adjacent at any vertex. E1 V4 V1 E4 24 E2 el V5 V2 E3 E6 ES V6 a) Check the following constraint graph. If it is not right, correct it. 06 V3 E7
