  Algorithm - Wikipedia, the free encyclopedia
Algorithms can be implemented by computer programs, although often in restricted forms; an error in the design of an algorithm for solving a problem can lead to failures in the implementing program.
Algorithms are essential to the way computers process information, because a computer program is essentially an algorithm that tells the computer what specific steps to perform (in what specific order) in order to carry out a specified task, such as calculating employees’ paychecks or printing students’ report cards.
Algorithms are not only implemented as computer programs, but often also by other means, such as in a biological neural network (for example, the human brain implementing arithmetic or an insect relocating food), or in electric circuits or in a mechanical device.

Random data structures formed in peer to peer networks are useful for a variety of purposes, increasing the resiliency of the network, efficient search and anonymity are three examples.
No auxiliary space is needed as implicit data structures are entirely encoded by a suitable permutation of the keys in a contiguous area of the memory.
The objective of input-sensitive data structures and input-sensitive analysis is to create data structures and algorithms whose runtime is expressed as a function of the patterns that occur in the input, with the goal of speeding up the performance, relative to input sequences that exhibit no favorable patters, or are completely random.

The NIST Dictionary of Algorithms and Data Structures is a reference work maintained by the U.S. National Institute of Standards and Technology.
For algorithms and data structures not necessarily mentioned here, see list of algorithms and list of data structures.
Note: Many, but not all, of the definitions in the Dictionary of Algorithms and Data Structures are in the public domain, since they were written by employees of the U.S. Federal Government acting as agents of the government.

 Dynamic Programming Algorithm, Edit Distance
treats a whole line as a "character" and uses a special edit-distance algorithm that is fast when the "alphabet" is large and there are few chance matches between elements of the two strings (files).
Algorithms related to the edit distance may be used in spelling correctors.
Algorithms similar to those for the edit-distance problem are used in some speech recognition systems: find a close match between a new utterance and one in a library of classified utterances.

 "Dictionary of Algorithms and Data Structures"
Whether you see it or not, almost every piece of data stored in the physical memory of a computer is defined as a data structure, and all reasonably advanced programming languages are capable of working with data structures.
In the old days, finding obscure algorithms and data structures meant keeping stacks of books and trade journals in the garage, visiting book stores and local universities to dig through mountains of books and badly written and copied research papers.
NIST Dictionary of Algorithms and Data Structures is useful too, although it's not as complete as I would like.

 Data Compression Algorithms   (Site not responding. Last check: 2007-10-18)
Data compression is explained with a focus on lossless text compression.
This means that the data is originally a combination of elements, e, from some alphabet, A.
The sliding dictionary method utilizes pointers within the compressed file that point to previously represented strings of bits within the file.

B-trees are tree data structures that are most commonly found in databases and filesystems.
B-trees keep data sorted and allow amortized logarithmic time insertions and deletions.
B-trees generally grow from the bottom up as elements are inserted, whereas most binary trees grow down.

For many programming problems there are several simple and elegant algorithms that have been invented, but some of them are better than other in practical situations.These algorithms undergone a tremendous amount of polishing and peer reviews and usually you can be confident in their correctness and efficiency.
And since the data is already distributed, the new partition should be similar to the current one to minimize the amount of data that needs to be redistributed.

One of aims of this course will be to introduce fundamental techniques for the design of algorithms, and ways to argue for their correctness and to analyze their efficiency.
Turning algorithms into computer programs requires the use of data structures, i.e., ways to organize data in computer memory so that certain key operations on data items can be efficiently performed.
An algorithm must be seen to be believed, and the best way to learn what an algorithm does is to try it.

 PRIMES is in P little FAQ   (Site not responding. Last check: 2007-10-18)
Note that there is no deterministic or randomized algorithm that is known to be able to solve the "subset sum problem" on arbitrary inputs in time bounded by a polynomial in the size of the inputs.
Note that a nondeterminstic algorithm does not constitute a reasonable definition of an algorithm in practice, contrary to randomized algorithms which are very reasonable in practice (and often used).
A non-deterministic algorithm can, however, be simulated by a deterministic algorithm by trying all possible choices and making sure that it doesn't get stuck prematurely in a non-terminating computation, but this is very inefficient (not bounded by a polynomial in the size of the input).
