Parent State ID: 81
State Depth: 9
Action Taken: right(robot1, tile_1-2, tile_1-3)
Action Reasoning: The robot1, currently on tile_1-2, is holding white. The next best action is to move right to tile_1-3, which is clear, to eventually paint the tile below it (tile_2-3) as it requires black for the goal state. Moving to tile_1-3 prepares for a color switch to black.
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 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)', 'change-color(robot1, black, white)', 'right(robot1, tile_1-2, tile_1-3)']

successfully verified the action of new state 108 with the path: The last action `right(robot1, tile_1-2, tile_1-3)` is valid as all preconditions are met, and the effects are correctly updated in the current state. The action moves the robot closer to the goal state, and the current state's description and visualization accurately reflect the sequence of actions taken.
