Parent State ID: 36
State Depth: 6
Action Taken: left(robot1, tile_1-3, tile_1-2)
Action Reasoning: Since row 2 is not fully painted yet, the robot should move left to tile_1-2 where it can paint the tile below it, tile_2-2, after a color change if necessary. This allows us to paint tile_2-2 in the next steps.
State Description: Tile_0-1: clear; Tile_0-2: clear; Tile_0-3: clear; Tile_1-1: clear; Tile_1-2: occupied by robot1 holding color black; Tile_1-3: clear; Tile_2-1: painted black; Tile_2-2: clear; Tile_2-3: clear. Robot1: on tile_1-2 holding color black. Color_white: available; Color_black: available.
Action Path: ['down(robot1, tile_0-1, tile_1-1)', 'change-color(robot1, white, black)', '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)', 'left(robot1, tile_1-3, tile_1-2)']

successfully verified the action of new state 62 with the path: The last action `left(robot1, tile_1-3, tile_1-2)` is valid because all preconditions are met: Robot1 was on `tile_1-3`, and `tile_1-2` was clear. The effects of the action are correctly reflected in the current state. The natural language description, diagram encoding, and visualization of the current state are consistent with the sequence of actions taken.
