Parent State ID: 133
State Depth: 12
Action Taken: change-color(robot1, black, white)
Action Reasoning: The robot is currently on tile_1-3 and holding black. The next step is to paint tile_1-3 white, as it is the target color for this tile in the goal state. Since the robot is holding black, it needs to change to white first.
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)', 'right(robot1, tile_1-1, tile_1-2)', 'right(robot1, tile_1-2, tile_1-3)', 'change-color(robot1, black, white)']

successfully verified the action of new state 146 with the path: The last action `change-color(robot1, black, white)` is valid because all preconditions are satisfied: robot1 was holding black, and white is available. The effects are correctly reflected in the current state, where robot1 is now holding white. The current state's description and visualization accurately represent the sequence of actions taken, and the action logically progresses towards the goal state.
