skip list

The mechanism used for this improvement is very similar to that of a skip list.

More recent alternatives include skip lists and calendar queues.

We can achieve an O(log n) time solution using skip lists.

Skip lists were first described in 1990 by William Pugh.

Skip graphs are a kind of distributed data structure based on skip lists.

A skip list is built in layers.

The unpleasant graininess of crab cake falafel put it on our skip list.

Skip lists are a probabilistic data structure that seem likely to supplant balanced trees as the implementation method of choice for many applications.

There has been some evidence that skip lists have worse real-world performance and space requirements than B trees due to memory locality and other issues.

Skip list algorithms have the same asymptotic expected time bounds as balanced trees and are simpler, faster and use less space.

Despite the title, this is primarily about treaps and skip lists; randomized binary search trees are mentioned only briefly.

In contrast to skip lists and other tree data structures, they are very resilient and can tolerate a large fraction of node fails.

Skip lists are sorted data structures that allow insertion, deletion and indexed retrieval in O(log n) time.

The elements used for a skip list can contain more than one pointer since they can participate in more than one list.

SkipDB, a BerkeleyDB-style database implemented using skip lists.

The skip list is a linked list augmented with layers of pointers for quickly jumping over large numbers of elements, and then descending to the next layer.

On average, each element appears in 1/(1-p) lists, and the tallest element (usually a special head element at the front of the skip list) in lists.

Redis, an ANSI-C open-source persistent key/value store for Posix systems, uses skip lists in its implementation of ordered sets.

William Worthington (Bill) Pugh Jr. is an American computer scientist who invented the skip list and the Omega test for deciding Presburger arithmetic.

This method of implementing indexing is detailed in Section 3.4 Linear List Operations in "A skip list cookbook" by William Pugh.

A skip list is a data structure for storing a sorted list of items using a hierarchy of linked lists that connect increasingly sparse subsequences of the items.

Such parallelism can be especially advantageous for resource discovery in an ad-hoc Wireless network because a randomized skip list can be made robust to the loss of any single node.

Once the data are sorted into this ordering, any one-dimensional data structure can be used such as binary search trees, B-trees, skip lists or (with low significant bits truncated) hash tables.

If a skip list is used, the insertion time is brought down to O(log n), and swaps are not needed because the skip list is implemented on a linked list structure.

Skip lists are also useful in parallel computing, where insertions can be done in different parts of the skip list in parallel without any global rebalancing of the data structure.
