Parent State ID: 177
State Depth: 15
Action Taken: right(robot1, tile_1-2, tile_1-3)
Action Reasoning: The robot is currently on tile_1-2, holding the color white. The next unpainted tile in row 1 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, aligning with the goal state.
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 painted white. 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)', 'up(robot1, tile_1-1, tile_0-1)', 'change-color(robot1, black, white)', 'paint-down(robot1, tile_1-1, tile_0-1, white)', 'right(robot1, tile_0-1, tile_0-2)', 'down(robot1, tile_0-2, tile_1-2)', 'right(robot1, tile_1-2, tile_1-3)']

successfully verified the action of new state 191 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, and the natural language and diagram encoding descriptions are accurate. The visualization matches the current state, confirming the validity of the action and state representation.
