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

Action Reasoning:
Since robot1 is on tile_1-1 with black and cannot paint below because tile_2-1 is already painted, the best action is to move right to a clear tile and prepare for the next appropriate paint or color change action. Moving to tile_1-2 is valid and aligns with the goal of painting row 1 with alternating colors.

New State Description:
- Robot1 is now on tile_1-2, holding the color black.- Tile_0-4 is clear.- Tile_1-1 is clear.- Tile_1-2 is occupied by robot1.- Tile_1-3, tile_1-4, tile_1-5 are clear.- Tile_2-1 is painted black.- Tile_2-2 is painted white.- Tile_2-3 is painted black.- Tile_2-4 is painted white.- Tile_2-5 is painted black.- Color white is available for switching.- Color black is available for switching.

Action Chosen:
