Please answer the following questions.
1. Which state should be selected to color first based on the heuristic of most constraining variable (degree heuristic)?
2. Assume our current assignment is {Nevada= Red, Arizona = Green}, which state(s) should be selected to color next based on the heuristic of minimum remaining
value?
3. Assume our current assignment is {Arizona = Blue, Utah = Red} and we select California to color next, which color should we select based on the heuristic of least
constraining value?
4. Assume our current assignment is {California = Red, Arizona = Blue, New Mexico = Green, Colorado = Red}, is this partial assignment consistent based on the arc-
consistency algorithm? Justify your answer by showing the sequence of arcs that you evaluated.
