Given the following 4-queens problem: (Q=Queen on the board). Q Q Q Q States can be represented by the number of the place each queen occupies on the board, from bottom to top, and from left to right. Therefore, this initial state would be [2,2,1,3]. Each queen can move only one space up or down if possible. A successor state is a state in which only ONE queen moves. Therefore, successor states will always be one move away from the state they are succeeding. Using the heuristic of "number of attacking pairs of queens, directly or indirectly," assume that the first move has cost 0 and every subsequent move has cost 3. O Which of the following states is the frontier (and their corresponding heuristic) at the first iteration? {[4,2,1,3] h=4; [2,2,1,3] h=5; [3,1,1,3] h=7; [3,3,1,3] h=6; [3,2,2,3] h=7; [3,2,1,2] h=8; [3,2,1,4] h=7} {[1,2,1,3]h=5;[3,3,1,3]h=7;[2,4,1,3]h=3; [2,2,1,3]h=5; [2,3,2,3]h=5;[2,3,1,2]h=4} {[3,2,1,3]h=3:[1,2,1,3]h=3;[2,3,1,3]h=2; [2,1,1,3]h=3; [2,2,1,4]h=3;[2,2,1,2]h=5} {[3,2,1,3]h=3:[1,2,1,3]h=3;[2,3,1,3]h=2; [2,2,1,3]h=5;[2,3,2,3]h=5;3,1,1,3] h=7}
