Consider the following constraint network of 8 variables. Assume each variable currently has
a domain of {1,2,3,4}. Find an equivalent arc-consistent and path-consistent network, and show this
equivalent network as a list of unary and binary constraints, e.g. D1={1,2,3,4}, C12={(1,2),(1,3)}, etc. Note the
examples of D1 and C12 are NOT the right answers. They are just examples.
