Parent State ID: 14
Action Taken: down(robot1, tile_1-4, tile_2-4)
Action Reasoning: The current state has Robot1 at tile_1-4, holding black paint. The goal is to paint the first row in an alternating pattern starting with black. The first step is to move Robot1 to tile_1-0. Since the robot is on tile_1-4, it should move left to reach tile_1-0. The shortest path to tile_1-0 involves moving left. The previous attempt to move left from tile_1-4 to tile_1-3 has already been explored, so the next logical step is to move Robot1 down from tile_1-4 to tile_2-4, which is a new state.
State Description: Robot1 is now on tile_2-4, holding black paint. Tile_1-4 is clear, and tile_2-4 is occupied by Robot1.
