Attempt Number: 3
Error Message: The action and resulting child state have already been explored.

Action Reasoning:
The robot is currently on tile_1-3 and holding a white paint gun. According to the goal, we need to paint tile_0-0 black first. The robot needs to move to tile_1-0. Since the robot is at tile_1-3, it should move left to reach tile_1-0. The next logical step is to move the robot left to tile_1-2, which is clear. This action avoids repeating the previous error, as it moves the robot closer to tile_1-0 without revisiting already explored states.

New State Description:
Robot1 has moved from tile_1-3 to tile_1-2. Tile_1-3 is now clear, and tile_1-2 is occupied by the robot. Robot1 is still holding the white paint gun.

Action Chosen:
left(robot1, tile_1-3, tile_1-2)
