Multiple issues original research December 2009 unreferenced December 2009 History of computer theory basically starts with in a pure sense by Alan Turing , who devised notion of Turing machine , Turing thesis , Church Turing hypothesis . Earlier form of computer theory might ve existed before Alan Turing and others, but Turing is considered by substantial number of people today to be an important figure in pure computer theory Can it be computed or not? , but not necessarly in computing something for practical purposes Can it be computed quickly? . The goal of computer theory is to answer the question, What is computable? There are many different ways to answer the question taking into account space and time needed to compute the problem, but the central question in computer theory is What can be computed efficiently within a certain and time constraints? This tries to focus computer theory to practical purposes and applications, instead of studying about a Turing machine that takes 200 years to compute something, which isn t practical in real world. The ultimate answer from the Turing machine test is that anything can be computed by ignoring time and space. From this the area of algorithm design came about to give solutions and basically to create faster and efficient algorithm to compute a real world problem.

Unreferenced date December 2009 A computation tree is a representation for the computation steps of a non deterministic Turing machine on a specified input. A computation tree graph theory tree is a rooted tree of nodes and edges. Each node in the tree represents a single computational state, while each edge represents a transition to the next possible computation. The number of nodes of the tree is the size of the tree and the length of the path from the root to a given node is the depth of the node. The largest depth of an output node is the depth of the tree. The output nodes of the tree are called leaves. In a computation tree each output node is labeled Yes or No. If a tree, T, with an input space X, if math x in X math and the path for x ends in node labeled yes, then the input x is accepted. Else it is rejected. The depth of the computation tree for a given input is the computation time for the Turing machine on that input. One of the primary methods of showing that a computational problem L is complete complexity complete for a given complexity class C is to show that the computation tree of any algorithm in C can be directly analyzed in terms of L .

Category Theory of computation Category ...In computer science , interactive computation is a mathematical model for computation that involves communication with the external world during the computation. This is in contrast to the traditional understanding of computation which assumes a simple interface between a computing agent and its environment, consisting in asking a question input and generating an answer output . The famous Church Turing thesis attempts to define computation and computability in terms of Turing machines . However the Turing machine model only provides an answer to the question of what computability of functions means and, with interactive tasks not always being reducible to functions, it fails to capture our broader intuition of computation and computability. While this fact was admitted by Alan Turing himself, it was not until recently that the theoretical computer science community realized the necessity to define adequate mathematical models of interactive computation. Among the currently studied mathematical models of computation that attempt to capture interaction are http www.csc.villanova.edu japaridz Japaridze s hard and easy play machines elaborated within the framework of computability logic , http www.cse.uconn.edu dqg Goldin s persistent Turing machines, and http research.microsoft.com gurevich Gurevich s abstract state machines.

In computability theory , the theory of real computation deals with hypothetical computing machines using infinite precision real number s. They are given this name because they operate on the set of real number s. Within this theory, it is possible to prove interesting statements such as the complement of the Mandelbrot set is only partially decidable . These hypothetical computing machines can be viewed as idealised analog computer s which operate on real numbers, whereas digital computer s are limited to computable numbers. They may be further subdivided into differential mathematics differential and algebraic models digital computers, in this context, should be thought of as topology topological , at least insofar as their operation on computable real s is concerned ref cite book title A Simple Introduction to Computable Analysis author Klaus Weihrauch year 1995 url http eccc.uni trier.de static books A Simple Introduction to Computable Analysis Fragments of a Book ref .

The temperature of the cosmic microwave background radiation gives a practical lower limit to the energy consumed to perform computation of approximately 4 kT per state change, where T is the temperature of the background about 3 kelvin s , and k is the Boltzmann constant . While a device could be cooled to operate below this temperature, the energy expended by the cooling would offset the benefit of the lower operating temperature . Bremermann s limit is the maximum computational speed of a self contained system in the material universe, and is based on mass energy versus quantum uncertainty constraints. Several methods have been proposed for producing computing devices or data storage devices that approach physical and practical limits A cold degenerate star could conceivably be used as a giant data storage device, by carefully perturbing it to various excited states, in the same manner as an atom or quantum well used for these purposes.

One can think of limit computable functions as those admitting an eventually correct computable guessing procedure at their true value.

Software applications that perform symbolic calculations are called computer algebra system s . These systems might be used for symbolic symbolic integration integration or derivative differentiation , substitution of one expression into another, simplification of an expression, etc., for most operations of calculus and, more generally, for every computation with mathematical objects for which algorithms are known. Computer algebra softwares are widely used in many scientific and engineering domains.
