Parent State ID: 115
State Depth: 11
Action Taken: right(robot1, tile_0-1, tile_0-2)
Action Reasoning: To advance towards the goal state, the robot should move to an adjacent clear tile, tile_0-2, to prepare for painting the next required tile in row 1. Moving right does not violate constraints and allows access to tiles that need painting.
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 clear. 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)', 'right(robot1, tile_0-1, tile_0-2)']

successfully verified the action of new state 138 with the path: The last action `right(robot1, tile_0-1, tile_0-2)` is valid as all preconditions are met, and the effects are correctly reflected in the current state. The natural language description, diagram encoding, and visualization accurately represent the state after the sequence of actions.
