Parent State ID: 3
Action Taken: change-color(robot1, white, black)
Action Reasoning: The robot is currently at tile_1-1 and holding a white paint gun. According to the goal state, the first tile to be painted is tile_0-0, which should be black. Since the robot is not at tile_1-0 yet, the first step is to move the robot to tile_1-0. However, since the previous attempt to move left resulted in an error, the next best action is to change the color of the paint gun to black, preparing the robot to paint tile_0-0 once it reaches tile_1-0.
State Description: Robot1 is still at tile_1-1, but it is now holding a black paint gun. Tile_1-2 is clear, and tile_1-1 is occupied by the robot.
Action Path: ['left(robot1, tile_1-4, tile_1-3)', 'left(robot1, tile_1-3, tile_1-2)', 'left(robot1, tile_1-2, tile_1-1)', 'change-color(robot1, white, black)']
