Attempt Number: 4
Error Message: Action not unique compared to other actions chosen from this state before. Choose a new action

Action Reasoning:
Since the robot is currently on tile_0-2 and holding the color black, and since it cannot paint because there are no tiles left to paint directly below it, the next logical step is to move the robot closer to unpainted tiles. Moving the robot right to tile_0-3 keeps the robot away from already painted areas while positioning it over the clear tile directly, allowing painting to start in a valid configuration.

New State Description:
Tile tile_0-1 is clear. Tile tile_0-2 is clear. Tile tile_0-3 is occupied by robot1. Tile tile_1-1 is painted white. Tile tile_1-2 is painted black. Tile tile_1-3 is clear. Tile tile_2-1 is painted black. Tile tile_2-2 is painted white. Tile tile_2-3 is painted black. Robot1 is on tile_0-3, holding color black. Colors white and black are available for switching.

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