Parent State ID: 19
State Depth: 5
Action Taken: change-color(robot1, white, black)
Action Reasoning: The robot is currently on tile_1-3 and holding the color white. The next tile to paint is tile_2-3, which should be black. Therefore, the robot should change its color to black to prepare for painting tile_2-3.
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)', 'right(robot1, tile_1-2, tile_1-3)', 'change-color(robot1, white, black)']

successfully verified the action of new state 42 with the path: The last action `change-color(robot1, white, black)` is valid because all preconditions are satisfied: the robot had color white, and black was available. The effects are correctly reflected in the current state, where the robot now holds color black. The current state's description and visualization accurately represent the sequence of actions taken, and the action logically progresses towards the goal state.
