2 Dictionary/membership Problem 3 Hashing with Chaining
نویسنده
چکیده
In dictionary/membership problem, we want to keep a set S of items with possibly some extra information associated with each one of them. (From now on, we denote the number of elements in S by n.) For the membership problem, the goal is to create a data structure that allows us to ask whether a given item x is in S or not. For a dictionary, the data structure should also return the infomation associated with x. For example, S can be a set of Swahili words such that each of the words is associated with a piece of text which describes its meaning. (Duh!)

Lecture 10 — March 20 , 2012
In the last lecture, we finished up talking about memory hierarchies and linked cache-oblivious data structures with geometric data structures. In this lecture we talk about different approaches to hashing. First, we talk about different hash functions and their properties, from basic universality to k-wise independence to a simple but effective hash function called simple tabulation. Then, we ...
متن کاملCSE 521 Winter 2006 Notes on Hashing
The dictionary data structure is ubiquitous in computer science. A dictionary holds a set of items from an ordered universe and supports the operations of inserting an item, deleting an item, and searching for an item (membership queries). This is the dynamic dictionary problem. If the set of items is fixed and never changes, we only need to efficiently support membership queries (of the form “...
متن کاملA Queueing Analysis of Hashing with Lazy Deletion
Hashing with lazy deletion is a simple method for maintaining a dynamic dictionary: items are inserted and sought as usual in a separate-chaining hash table; however, items that no longer need to be in the data structure remain until a later insertion operation stumbles on them and removes them from the table. Because hashing with lazy deletion does not delete items as soon as possible, it keep...
متن کاملDe Dictionariis Dynamicis Pauco Spatio Utentibus (lat. On Dynamic Dictionaries Using Little Space)
We develop dynamic dictionaries on the word RAM that use asymptotically optimal space, up to constant factors, subject to insertions and deletions, and subject to supporting perfect-hashing queries and/or membership queries, each operation in constant time with high probability. When supporting only membership queries, we attain the optimal space bound of Θ(n lg u n ) bits, where n and u are th...
متن کاملType-2 Fuzzy Hybrid Expert System For Diagnosis Of Degenerative Disc Diseases
One-third of the people with an age over twenty have some signs of degenerated discs. However, in most of the patients the mere presence of degenerative discs is not a problem leading to pain, neurological compression, or other symptoms. This paper presents an interval type-2 fuzzy hybrid rule-based system to diagnose the abnormal degenerated discs where pain variables are represented by interv...
