    摘要: An apparatus and method for sorting items using a longest increasing subsequence are disclosed. Item sorting may be performed by selecting excluded items, which correspond to a longest increasing subsequence, from among items in an item list, selecting update items by excluding the excluded items from the items, and performing update for the update items. It is possible to more efficiently use a system by selecting items to be updated from among various items in an item list and updating them to reduce the system workload for updating the items.
