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

Action Reasoning:
Since robot1 is currently holding the color white and is positioned on tile_2-2, the next best action is to paint the tile directly below it, tile_3-2. However, tile_3-2 is already painted black, so the most strategic move is to change the robot's color to black in preparation for painting tile_1-2 black.

New State Description:
- Robot Position and Paint:  - Robot1 is on tile_2-2, holding the color black.- Tiles Status:  - Row 0: tile_0-1, tile_0-2, tile_0-3 are clear.  - Row 1: tile_1-1 is painted white, tile_1-2 and tile_1-3 are clear.  - Row 2: tile_2-1 is clear, tile_2-2 is occupied by robot1, tile_2-3 is clear.  - Row 3: tile_3-1 is painted white, tile_3-2 is painted black, tile_3-3 is painted white.- Available Colors:  - White and black are available for switching.
