We consider efficient algorithms for combinatorial optimization problems arising in automatic double-layered food packing equipments. The first and second layers consist of $n$ weighing hoppers and $n$ booster hoppers, respectively. Some amount of foods is thrown into each hopper, and is called an item. The equipment performs an operation of choosing a subset $I
