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 action should be to paint tile_1-5 white, as it is the only remaining tile in row 1 that needs to be painted to achieve the goal state. Robot1 is already holding the color white and is positioned directly above tile_1-5, making this the optimal next step.

New State Description:
- Robot1 is on tile_0-5, holding the color white.- Tile_0-5 is occupied by Robot1.- Tile_0-4 is clear.- Tile_1-1 is painted white and is no longer clear.- 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.- The colors white and black are available for switching.- All tiles in row 1 are now painted according to the goal state.

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