Parent State ID: 53
State Depth: 7
Action Taken: right(robot1, tile_1-1, tile_1-2)
Action Reasoning: To progress, the robot should move to the right so it can eventually paint the tile below it (tile_2-1) without contradiction. This keeps it moving towards the goal of painting both the black and white tiles in the correct order.
State Description: Tile tile_0-1 is clear. Tile tile_0-2 is clear. Tile tile_0-3 is clear. Tile tile_1-1 is clear. Tile tile_1-2 is occupied by robot1 holding color black. Tile tile_1-3 is clear. Tile tile_2-1 is clear. Tile tile_2-2 is painted white. Tile tile_2-3 is painted black. Robot1 is on tile_1-2, holding color black. Colors white and black are available for switching.
