This New Algorithm for Sorting Books or Files Is Close to Perfection
Briefly

A recent algorithm has made significant strides in solving the 'library sorting problem,' which addresses the optimal organization of books to expedite the placement of new additions. Presented by a team at a Foundations of Computer Science conference, the algorithm aims to minimize movement on shelves, ultimately enhancing file management systems in computing. The challenge of distributing unoccupied space efficiently can significantly reduce wait times in situations where billions of items are arranged. This algorithm could revolutionize how libraries and digital systems organize their data.
The challenge is to devise a strategy for organizing books in some kind of sorted order that minimizes how long it takes to place a new book on the shelf.
This problem was introduced in a 1981 paper, and it goes beyond simply providing librarians with organizational guidance; it also applies to the arrangement of files on hard drives.
