Parent State ID: 78
State Depth: 9
Action Taken: paint-down(robot1, tile_2-1, tile_1-1, black)
Action Reasoning: Robot1 should paint the tile directly below it, tile_2-1, which aligns with the goal color pattern and is a valid action from the current position.
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. Tile tile_1-2 is clear. Tile tile_1-3 is clear. Tile tile_2-1 is painted black. 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)', 'right(robot1, tile_1-2, tile_1-3)', 'left(robot1, tile_1-3, tile_1-2)', 'left(robot1, tile_1-2, tile_1-1)', 'paint-down(robot1, tile_2-1, tile_1-1, black)']

successfully verified the action of new state 101 with the path: The last action is valid because all preconditions are satisfied: the robot is on the correct tile, holding the correct color, and the target tile is clear. The effects of the action are correctly reflected in the current state. The natural language description, diagram encoding, and visualization accurately represent the current state after the sequence of actions.
