Shellsort is an optimization of insertion sort that allows the exchange of items that are far apart. The idea is to arrange the list of elements so that, starting anywhere, taking every hth element produces a sorted list. Such a list is said to be h-sorted. It can also be thought of as h interleaved lists, each individually sorted. Beginning with large values of h allows elements to move long distances in the original list, reducing large amounts of disorder quickly, and leaving less work fo… WebJan 27, 2016 · This sorting is a generalization of insertion sort that allows the exchange of items that are far apart It starts by comparing elements that are far apart and gradually reduces the gap between elements being compared.
