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

Action Reasoning:
The next best action is to paint tile_1-5 white. Robot1 is already holding white and is positioned directly above tile_1-5, which is clear and needs to be painted white according to the goal state. This action brings us closer to completing the goal pattern in row 1.

New State Description:
- Robot1 is on tile_0-3, holding the color white.- Tile_0-3 is occupied by Robot1.- Tile_1-2 is painted black and is no longer clear.- Tile_1-3 is painted white and is no longer clear.- Tile_1-4 is painted black and is no longer clear.- Tile_1-5 is painted white and is no longer clear.- Tiles tile_0-1, tile_0-2, tile_0-4, tile_0-5, and tile_1-1 remain clear and unpainted.- The colors white and black are available for switching.

Action Chosen:
paint-down(robot1, tile_1-5, tile_0-3, white)
