Parent State ID: 178
State Depth: 15
Action Taken: up(robot1, tile_0-2, tile_0-1)
Action Reasoning: Since row 2 is completely painted, the robot should be moved up from tile_0-2 to tile_0-1, while holding the black color, to prepare for future painting actions.
State Description: Tile tile_0-1 is occupied by robot1. 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 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_0-1, 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)', 'right(robot1, tile_0-1, tile_0-2)', 'change-color(robot1, white, black)', 'up(robot1, tile_0-2, tile_0-1)']

successfully verified the action of new state 196 with the path: The last action `up(robot1, tile_0-2, tile_0-1)` 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 allowing the robot to reposition for further painting. The natural language description and visualization accurately represent the current state after the sequence of actions.
