Abstract: An application program updating method, apparatus, system, medium and device. The application program updating method provides a method of debugging a to-be-updated program logic through a development mode of a hot-update supporting client to obtain an updated program logic, then issuing the updated program logic to a back-end, and acquiring update data from the back end through a product mode of the hot-update supporting client. This allows a front-end developer to write and update simply and quickly without an assistance of any back-end developers.

Abstract: The disclosed embodiments provide computer-implemented systems and methods for batch picking optimization. The system may include one or more memory devices storing instructions and one or more processors configured to execute the instructions to receive an order comprising one or more items for picking. Additionally, the system may calculate one or more high density areas in a fulfillment center by calculating distances between a first item in the one or more items and at least one other item in the one or more items using a search algorithm. Additionally, the system may calculate nearest neighboring items for the one or more items and generate a high density area by choosing a plurality of the nearest neighboring items.
