Parent State ID: 160
State Depth: 14
Action Taken: right(robot1, tile_1-2, tile_1-3)
Action Reasoning: The robot needs to paint tile_1-3 white to match the goal state. Since the robot is currently on tile_1-2 and holding white, it should move right to tile_1-3 to prepare for painting.
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 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 white. 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)', 'change-color(robot1, black, white)', 'right(robot1, tile_1-1, tile_1-2)', 'right(robot1, tile_1-2, tile_1-3)', 'left(robot1, tile_1-3, tile_1-2)', 'right(robot1, tile_1-2, tile_1-3)']

successfully verified the action of new state 180 with the path: The last action `right(robot1, tile_1-2, tile_1-3)` is valid as all preconditions are met in the parent state, and the effects are correctly reflected in the current state. The action logically progresses towards the goal state by positioning the robot to paint `tile_1-3` white. The natural language and diagram encoding descriptions are accurate, and the visualization correctly represents the current state.
