TīmeklisA skip list is equivalent to a randomly balanced binary search tree (RBST) in the way that is explained in more detail in Dean and Jones' "Exploring the Duality Between … Tīmeklis1. Skip Lists¶. This module presents a probabilistic search structure called the skip list.Like the BST, skip lists are designed to overcome a basic limitation of array-based and linked lists: Either search or update operations require linear time.The skip list is an example of a probabilistic data structure, because it makes some of its decisions …

TīmeklisThe skip list is a probabilisitc data structure that is built upon the general idea of a linked list. The skip list uses probability to build subsequent layers of linked lists upon an original linked list. Each additional layer of links contains fewer elements, but no new elements. You can think about the skip list like a subway system.

TīmeklisWe can devise a simple randomized data structure, called the skip list, which has the same logarithmic time bounds for searching as is achieved by the binary searching algorithm. Nevertheless, the bounds are expected for the skip list, while they are worst-case bounds for binary searching in a look-up table.
