Attempt Number: 2
Error Message: The action and resulting state have already been explored.

Action Reasoning:
The robot is currently on tile_1-3 and holding white paint. The goal is to paint the first row in an alternating color pattern starting with black. Since the robot is not yet at tile_1-0, it should move towards tile_1-0. The shortest path is to continue moving left. Therefore, the next best action is to move the robot left from tile_1-3 to tile_1-2.

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. The robot is still holding the white paint gun.

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