Parent State ID: 113
State Depth: 11
Action Taken: right(robot1, tile_1-1, tile_1-2)
Action Reasoning: The next best action is to move the robot to the right to tile_1-2, as this will position the robot to paint the tile directly below it (tile_2-2) white, which matches the goal state. This aligns with the goal of having tile_2-2 painted white, and positions the robot correctly for subsequent painting without violating constraints.
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 clear. Tile tile_1-2 is occupied by robot1. 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_1-2, 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)', 'change-color(robot1, black, white)', 'right(robot1, tile_1-1, tile_1-2)']

successfully verified the action of new state 129 with the path: The last action `right(robot1, tile_1-1, tile_1-2)` is valid as all preconditions are met, and the effects are correctly reflected in the current state. The action moves the robot closer to painting `tile_1-2`, aligning with the goal state. The natural language description and visualization accurately represent the current state.
