Parent State ID: 173
State Depth: 15
Action Taken: change-color(robot1, black, white)
Action Reasoning: Since all tiles in row 2 are already painted, the robot should now focus on painting row 1. Starting from the rightmost clear tile in row 1, moving right and then down, will allow the robot to paint tile_1-3, which needs to be white. However, as the robot is currently holding black, it first needs to change color to white.
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 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)', 'change-color(robot1, white, black)', 'right(robot1, tile_0-1, tile_0-2)', 'change-color(robot1, black, white)']

successfully verified the action of new state 188 with the path: The last action `change-color(robot1, black, white)` is valid because all preconditions are met: robot1 was holding black, and white was available. The effects are correctly reflected in the current state, where robot1 is now holding white. The natural language description and visualization of the current state are accurate and consistent with the sequence of actions taken.
