- Consider the following constraint network. Note that
*(X+Y) mod 2=1*means that*X+Y*is odd.

Is this constraint network arc consistent? If it is, explain why. If it isn't, explain which arc is not arc consistent and why it isn't arc consistent. - Consider the following constraint network:

Is this constraint network arc consistent? If it is, explain why. If it isn't, explain which arc is not arc consistent and why it isn't arc consistent.
