Cоnstrаint Questiоn (оn the Austrаliа graph coloring problem is described below): Five nodes WA-NT-Q-NSW-V are on a chain, and SA is connected to all those 5 nodes,. Modified domains for this question are as follows: SA={b}, and each of the other domains is {r, g}. Show each step of running the Forward Checking algorithm in the text-box, running EXACTLY in the sequence of SA, WA, NT, Q, NSW, and then V.
