Parent State ID: 110
State Depth: 10
Action Taken: right(robot1, tile_1-1, tile_1-2)
Action Reasoning: The robot is currently on tile_1-1 and holding black. To proceed, we can move the robot to tile_1-2 where it can prepare to paint tile_1-2 black, as it matches the goal. Moving to tile_1-2 is a preparatory step.
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 occupied by robot1. Tile tile_1-3 is clear. 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_1-2, 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)', 'paint-down(robot1, tile_2-3, tile_1-2, black)', 'left(robot1, tile_1-2, tile_1-1)', 'down(robot1, tile_1-1, tile_2-1)', 'up(robot1, tile_2-1, tile_1-1)', 'paint-down(robot1, tile_2-1, tile_1-1, black)', 'right(robot1, tile_1-1, tile_1-2)']

successfully verified the action of new state 117 with the path: The last action `right(robot1, tile_1-1, tile_1-2)` is valid as all preconditions are met, and the effects are correctly reflected in the current state. The action moves the robot closer to achieving the goal state by positioning it to paint `tile_1-2` black. The natural language and diagram encoding descriptions are consistent with the sequence of actions, and the visualization accurately represents the current state.
