Parent State ID: 215
State Depth: 18
Action Taken: up(robot1, tile_1-2, tile_0-2)
Action Reasoning: All tiles in row 2 are painted, so the robot should move up from tile_1-2 to tile_0-2 and prepare to paint tile_1-3.
State Description: Tile tile_0-1 is clear. Tile tile_0-2 is occupied by robot1. Tile tile_0-3 is clear. Tile tile_1-1 is painted white. Tile tile_1-2 is clear. 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_0-2, 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)', '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)', 'up(robot1, tile_1-1, tile_0-1)', 'change-color(robot1, black, white)', 'paint-down(robot1, tile_1-1, tile_0-1, white)', 'change-color(robot1, white, black)', 'right(robot1, tile_0-1, tile_0-2)', 'right(robot1, tile_0-2, tile_0-3)', 'down(robot1, tile_0-3, tile_1-3)', 'left(robot1, tile_1-3, tile_1-2)', 'up(robot1, tile_1-2, tile_0-2)']

successfully verified the action of new state 235 with the path: The last action `up(robot1, tile_1-2, tile_0-2)` is valid because all preconditions are met: Robot1 was on `tile_1-2`, and `tile_0-2` was clear. The effects of the action are correctly reflected in the current state, with Robot1 now on `tile_0-2` and `tile_1-2` clear. The visualization and natural language description accurately represent the current state, and the action logically progresses towards the goal state by allowing the robot to paint row 1 next.
