Parent State ID: 36
Action Taken: change-color(robot1, white, black)
Action Reasoning: In the current state, Robot1 is holding a white paint gun and occupies tile_1-1. The robot is ready to paint tile_0-1, which is directly above and not yet painted. According to the rules, if the last action was changing the color of the paint gun (as it was), the next action should be to paint-up. The previously chosen action was already explored, leading to a failure. Instead, based on the logic, Robot1 should first change the color of the paint gun to black before continuing to paint the next unpainted tile in the target sequence. This ensures an alternating color pattern, which aligns with the goal state.
State Description: Robot1 is now holding the black paint gun while occupying tile_1-1. The robot is ready to paint the next tile above it with black.
