Attempt Number: 4
Error Message: The action change-color(robot1, black, white) has already been explored.

Action Reasoning:
The last action taken was a move to the right, placing Robot1 on tile_1-1. According to the logical conclusions, after a move, the next best action is to change the color of the paint gun. Since the goal requires an alternating pattern starting with black on tile_0-0, the next tile, tile_0-1, should be painted white. Therefore, the robot should change its paint gun color from black to white to prepare for painting tile_0-1.

New State Description:
Robot1 is on tile_1-1, holding a white paint gun. Tile_1-0 is clear, and tile_1-1 is occupied by Robot1. Tile_0-0 is painted black, and tile_0-1 is not painted yet.

Action Chosen:
change-color(robot1, black, white)
