Parent State ID: 135
State Depth: 12
Action Taken: right(robot1, tile_1-2, tile_1-3)
Action Reasoning: The robot is currently on tile_1-2 and holding the color white. The next tile to paint is tile_1-3, which needs to be painted white. Moving right to tile_1-3 will allow the robot to paint it in the next 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 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)', 'change-color(robot1, black, white)', 'right(robot1, tile_1-2, tile_1-3)']

successfully verified the action of new state 149 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 reflected in the current state. The action logically progresses towards the goal state by positioning Robot1 to paint `tile_1-3` white. The natural language description, diagram encoding, and visualization of the current state are accurate and consistent with the sequence of actions taken.
