Attempt Number: 3
Error Message: Action not unique compared to other actions chosen from this state before. Choose a new action

Action Reasoning:
Since robot1 is on tile_0-3 and holding black, the best action is to move left to tile_0-2, which is clear. This positions the robot to eventually paint tile_1-2 with black, getting us closer to the goal state.

New State Description:
- Robot1 is on tile_0-2, holding the color black.- Tile_0-1 is clear.- Tile_0-2 is occupied by robot1 holding color black.- Tile_0-3 is clear.- Tile_1-1 is clear.- Tile_1-2 is clear.- Tile_1-3 is painted white.- Tile_2-1 is painted black.- Tile_2-2 is painted white.- Tile_2-3 is painted black.- Tile_3-1 is painted white.- Tile_3-2 is painted black.- Tile_3-3 is painted white.- White and black are available for switching.

Action Chosen:
left(robot1, tile_0-3, tile_0-2)
