Attempt Number: 6
Error Message: Action not unique compared to other actions chosen from this state before. Choose a new action

Action Reasoning:
Since row 2 needs to be painted first, the best action is to move robot1 down to tile_1-2. This positions the robot to begin painting tile_2-2 directly below it, aligning with the constraints and goal.

New State Description:
Tile tile_0-2 is now clear. Robot1 is on tile_1-2 holding color white. All tiles in row 0 are clear. Tile_1-1 and tile_1-3 are clear. All tiles in row 2 are clear. Colors white and black are available for switching.

Action Chosen:
down(robot1, tile_0-2, tile_1-2)
