Parent State ID: 40
State Depth: 6
Action Taken: left(robot1, tile_1-2, tile_1-1)
Action Reasoning: The robot is currently on tile_1-2 holding black, and can paint tile_2-2, but since tile_2-2 is already painted white, we should move the robot to a clear tile on row 2 to paint the remaining tiles. The best move is to go left to tile_1-1 to clear a path for painting tile_2-1.
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 occupied by robot1 holding color black. Tile tile_1-2 is clear. 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_1-1, holding color black. Colors white and black are available for switching.
Action Path: ['right(robot1, tile_0-1, tile_0-2)', 'down(robot1, tile_0-2, tile_1-2)', 'paint-down(robot1, tile_2-2, tile_1-2, white)', 'change-color(robot1, white, black)', 'paint-down(robot1, tile_2-3, tile_1-2, black)', 'left(robot1, tile_1-2, tile_1-1)']

successfully verified the action of new state 50 with the path: The last action `left(robot1, tile_1-2, tile_1-1)` is valid because all preconditions are satisfied: the robot was on `tile_1-2`, and `tile_1-1` was clear. The effects are correctly updated in the current state: the robot is now on `tile_1-1`, and `tile_1-2` is clear. The natural language description and visualization accurately reflect the current state, with all objects from the initial state present.
