Parent State ID: 99
Action Taken: left(robot1, tile_1-4, tile_1-3)
Action Reasoning: The last action taken was "paint-up," which means the robot should now move horizontally to continue painting the row above. Since the robot is currently on tile_1-4 and the row above (row 0) still has unpainted tiles, the robot should move left to tile_1-3. This will position the robot to paint the next unpainted tile in row 0, which is tile_0-3. Moving left is the best action to continue the pattern and get closer to the goal state.
State Description: Robot1 moves from tile_1-4 to tile_1-3, making tile_1-4 clear and occupying tile_1-3. Robot1 is still holding white paint.
