  1. Computational irreducibility

    Computational irreducibility is one of the main ideas proposed by Stephen Wolfram in his book A New Kind of Science . The idea Wolfram terms the inability to shortcut a program e.g., a system , or otherwise describe its behavior in a simple way, computational irreducibility . The empiricism empirical fact is that the world of simple programs contains a great diversity of behavior , but, because of undecidability , it is impossible to predict what they will do before essentially running them. The idea demonstrates that there are occurrences where theory s predictions are effectively not possible. Wolfram states several phenomena are normally computationally irreducible. Computational irreducibility explains observed limitations of existing mainstream science. In cases of computational irreducibility, only observation and experiment can be used. Computational irreducibility may also provide a scientific based resolution for free will . Implications Nearly no easy theory for any behavior that seems ...

  1. Irreducibility

    Other uses Onesource date March 2008 The principle of Irreducibility , in philosophy , has the sense that a complete account of an entity will not be possible at lower levels of explanation and which has novel properties beyond prediction and explanation. Another way to state this is that Occam s razor requires the elimination of only those entities that are unnecessary, not as many entities as could conceivably be eliminated. Lev Vygotsky provides the following illustration of the idea, in his Thought and Language Two essentially different modes of analysis are possible in the study of psychology psychological structures. It seems to us that one of them is responsible for all the failures that have beset former investigators of the old problem, which we are about to tackle in our turn, and that the other is the only correct way to approach it. The first method analyzes complex psychological wholes into wiktionary element elements . It may be compared to the chemical analysis of water into hydrogen and oxygen , neither of which possesses the properties of the whole and each of which possesses properties not present in the whole. The student applying this method in looking for an explanation of some property of water &mdash why it extinguishes fire, for example &mdash will find to his surprise that hydrogen burns and oxygen sustains fire .... In our opinion the right course to follow is to use the other type of analysis, which may be called analysis into units . By unit , we mean a product of analysis which, unlike elements, retains all the basic properties of the whole, and which cannot be further divided without losing them. Not the chemical composition of water, but its molecules and their behaviour, are the key to the understanding of the properties of water ... In other words to conserve the properties under investigation, it is necessary to remain within a certain level of complexity. Irreducibility is most often deployed in defence of the reality of human subjectivity ...   more details

  1. Irreducibility (mathematics)

    Unreferenced date December 2009 In mathematics , the concept of irreducibility is used in several ways. In abstract algebra , irreducible can be an abbreviation for irreducible element for example an irreducible polynomial . In representation theory , an irreducible representation is a nontrivial representation theory representation with no nontrivial proper subrepresentations. Similarly, an irreducible module is another name for a simple module . Absolutely irreducible is a term applied to mean irreducible , even after any finite extension of the field mathematics field of coefficients. It applies in various situations, for example to irreducibility of a linear representation , or of an algebraic variety where it means just the same as irreducible over an algebraic closure . In commutative algebra , a commutative ring R is irreducible if its prime spectrum , that is, the topological space Spec R , is an irreducible topological space . A directed graph is irreducible if, given any two vertices, there exists a path from the first vertex to the second see also Connectivity graph theory connectivity in graphs . A digraph is irreducible if and only if its adjacency matrix is irreducible. In a related notion, a matrix mathematics matrix is irreducible if it is not similar matrix similar to a block upper triangular matrix with two blocks via a permutation matrix permutation . Replacing non zero entries in the matrix by one, and viewing the matrix as an adjacency matrix of a graph, the matrix is irreducible if and only if the graph is irreducible. Also, a Markov chain is Markov chain Reducibility irreducible if there is a non zero probability of transitioning even if in more than one step from any state to any other state.

  1. Abel's irreducibility theorem

    In mathematics, Abel s irreducibility theorem , a field theory mathematics field theory result described in 1829 by Niels Henrik Abel , asserts that if &fnof x is a polynomial over the a field mathematics field F that shares a root with an irreducible polynomial g x , then &fnof x is divisible evenly by g x i.e. &fnof x can be factored as g x h x with h having coefficients in  F . In other words, if a polynomial shares at least one root with an irreducible polynomial, it necessarily shares all the roots of the irreducible polynomial. Corollaries of the theorem include If &fnof x is irreducible, there is no lower degree polynomial other than the zero polynomial that shares any root with it. For example, x sup 2 sup   &minus   2 is irreducible over the rational number s and has math sqrt 2 math as a root hence there is no linear or constant polynomial over the rationals having math sqrt 2 math as a root. Furthermore, there is no same degree polynomial that shares any roots with &fnof x , other than constant multiples of &fnof x . If &fnof x   &ne   g x are both monic irreducible, they share no roots.

  1. Hilbert's irreducibility theorem

    In number theory , Hilbert s irreducibility theorem , conceived by David Hilbert , states that every finite number of irreducible polynomial s in a finite number of variables and having rational number coefficients admit a common specialization of a proper subset of the variables to rational numbers such that all the polynomials remain irreducible. This theorem is a prominent theorem in number theory. Formulation of the theorem Hilbert s irreducibility theorem. Let math f 1 X 1, ldots, X r, Y 1, ldots, Y s , ldots, f n X 1, ldots, X r, Y 1, ldots, Y s , math be irreducible polynomials in the ring math mathbb Q X 1, ldots, X r, Y 1, ldots, Y s . , math Then there exists an r tuple of rational numbers a sub 1 sub ,..., a sub r sub such that math f 1 a 1, ldots, a r, Y 1, ldots, Y s , ldots, f n a 1, ldots, a r, Y 1, ldots, Y s , math are irreducible in the ring math mathbb Q Y 1, ldots, Y s . , math Remarks. It follows from the theorem that there are infinitely many r tuples. In fact the set of all irreducible specialization, called Hilbert set, is large in many senses. For example, this set is Zariski topology Zariski dense in math mathbb Q r math There are always infinitely many integer specializations, i.e., the assertion of the theorem holds even if we demand a sub 1 sub ,..., a sub r sub to be integers. There are many Hilbertian field s, i.e., fields satisfying Hilbert s irreducibility theorem. For example, global field s are Hilbertian. The irreducible specialization property stated in the theorem is the most general. There are many reductions, e.g., it suffices to take math n r s 1 math in the definition.

  1. Cohn's irreducibility criterion

    Arthur Cohn s irreducibility criterion is a test to determine whether a polynomial is irreducible polynomial irreducible in polynomial ring math mathbb Z x math . The criterion is often stated as follows If a prime number math p math is expressed in base exponentiation base 10 as math p a m10 m a m 1 10 m 1 dots a 110 a 0 math where math 0 leq a i leq 9 math then the polynomial math f x a mx m a m 1 x m 1 dots a 1x a 0 math is irreducible in math mathbb Z x math . The theorem can be generalized to other bases as follows Assume that math b ge 2 math is a natural number and math p x a kx k a k 1 x k 1 dots a 1x a 0 math is a polynomial such that math 0 leq a i leq b 1 math . If math p b math is a prime number then math p x math is irreducible in math mathbb Z x math .

  1. Computational resource

    Refimprove date September 2007 In computational complexity theory , a computational resource is a resource used by some computational model s in the solution of computational problem s. The simplest computational resources are computation time , the number of steps necessary to solve a problem, and memory space , the amount of storage needed while solving the problem, but many more complicated resources have been defined. A computational problem is generally defined in terms of its action on any valid input. Examples of problems might be given an integer n , determine whether n is prime , or given two numbers x and y , calculate the product x y . As the inputs get bigger, the amount of computational resources needed to solve a problem will increase. Thus, the resources needed to solve a problem are described in terms of asymptotic analysis , by identifying the resources as a function of the length or size of the input. Computational resources are useful because we can study which problems can be computed in a certain amount of each computational resource. In this way, we can determine whether algorithm s for solving the problem are optimal and we can make statements about an Algorithmic efficiency algorithm s efficiency . The set of all of the computational problems that can be solved using a certain amount of a certain computational resource is a complexity class , and relationships between different complexity classes are one of the most important topics in complexity theory.

  1. Computational thinking

    Computational Thinking is a new problem solving method, named for its extensive use of computer science techniques. The term computational thinking was first used by Seymour Papert in 1996. ref http www.papert.org articles AnExplorationintheSpaceofMathematicsEducations.html ref Computational thinking can be used to algorithm algorithmically solve complicated problems of scale, and is often used to realize large improvements in efficiency. ref http www.cs.cmu.edu CompThink Computational thinking ref Overview The phrase computational thinking was brought to the forefront of the computer science community as a result of an Association for Computing Machinery ACM Communications article on the subject by Jeannette Wing Jeannette M. Wing. ref http doi.acm.org 10.1145 1118178.1118215 ACM ref The article suggested that thinking computationally was a fundamental skill for everyone, not just computer scientists, and argued for the importance of integrating computational ideas into other disciplines. Center of Computational Thinking Computational thinking today is spearheaded by the Center of Computational Thinking at Carnegie Mellon . The Center s major activity is conducting PROBEs or PROB lem oriented E xplorations. These PROBEs are experiments that apply novel computing concepts to problems to show the value of computational thinking.
