Parent State ID: 11
State Depth: 4
Action Taken: paint-down(robot1, tile_2-2, tile_1-2, black)
Action Reasoning: The robot is on tile_1-2 and holding the color black, matching the target color for tile_2-2. To progress towards the goal, we should paint tile_2-2.
State Description: (tile_0-1: clear, tile_0-2: clear, tile_0-3: clear, tile_1-1: clear, tile_1-2: clear, tile_1-3: clear, tile_2-1: clear, tile_2-2: painted black, tile_2-3: clear, robot1: on tile_1-2 holding color black, color_white: available, color_black: available)
Action Path: ['down(robot1, tile_0-1, tile_1-1)', 'change-color(robot1, white, black)', 'right(robot1, tile_1-1, tile_1-2)', 'paint-down(robot1, tile_2-2, tile_1-2, black)']

successfully verified the action of new state 33 with the path: The last action `paint-down(robot1, tile_2-2, tile_1-2, black)` is valid as all preconditions are met, and the effects are correctly reflected in the current state. The natural language description and visualization accurately represent the state after the sequence of actions.
