Parent State ID: 186
State Depth: 16
Action Taken: right(robot1, tile_1-2, tile_1-3)
Action Reasoning: Since the robot is on tile_1-2 and holding black, it should paint tile_2-2. However, tile_2-2 is already painted white, so the robot should move to tile_1-3 to paint tile_2-3 black, which is the next unpainted tile below it that matches the goal state.
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 painted white. Tile tile_1-2 is clear. Tile tile_1-3 is occupied by robot1. 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_1-3, 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)', 'up(robot1, tile_1-1, tile_0-1)', 'change-color(robot1, black, white)', 'paint-down(robot1, tile_1-1, tile_0-1, white)', 'change-color(robot1, white, black)', 'right(robot1, tile_0-1, tile_0-2)', 'down(robot1, tile_0-2, tile_1-2)', 'right(robot1, tile_1-2, tile_1-3)']

successfully verified the action of new state 198 with the path: The last action `right(robot1, tile_1-2, tile_1-3)` is valid as all preconditions are met, and the effects are correctly reflected in the current state. The action logically moves the robot closer to achieving the goal state. The natural language description, diagram encoding, and visualization of the current state are all accurate and consistent with the sequence of actions taken.
