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

Action Reasoning:
To move towards the goal state, we need to paint tile_1-1 white. Robot1 is already holding white and must be positioned above tile_1-1. Moving Robot1 left to tile_0-2 positions it to eventually move to tile_0-1, where it can paint downward.

New State Description:
- Robot1 is now on tile_0-2, holding the color white.- Tile_0-2 is occupied by Robot1.- Tiles tile_0-1, tile_0-4 remain clear and unpainted.- Tiles tile_1-1, tile_1-2, tile_1-3, tile_1-4, and tile_1-5 are painted, except tile_1-1 which is still clear.- The colors white and black are available for switching.

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