Parent State ID: 18
State Depth: 5
Action Taken: right(robot1, tile_1-2, tile_1-3)
Action Reasoning: The robot should move right to tile_1-3, which is clear, to position itself for painting tile_2-3 black, aligning with 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 clear. Tile tile_1-2 is clear. Tile tile_1-3 is occupied by robot1. Tile tile_2-1 is clear. Tile tile_2-2 is painted white. Tile tile_2-3 is clear. 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)', 'right(robot1, tile_1-2, tile_1-3)']

successfully verified the action of new state 39 with the path: The last action `right(robot1, tile_1-2, tile_1-3)` is valid because all preconditions are satisfied, 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 taken.
