It was introduced by Alonzo Church and Stephen Kleene in the 1930s; Church used the lambda calculus in 1936 to solve the Entscheidungsproblem . (He actually proved the non-existence of the sought algorithm that would have been considered a "solution" to the Entscheidungsproblem.) The calculus can be used to cleanly define what a "computable function" is. The question of whether two lambda calculus expressions are equivalent cannot be solved by a general algorithm, and this was the first question, even before the halting problem , for which undecidability could be proved.

Lambda Module Users' Manual Purpose This document provides information on using the predicates exported from the lambda module. It assumes the user has a strong grasp of Prolog logic programming, and, as this users' manual is not an introduction to functional programming and the lambda calculus, it will not dwell on introductory material of either. The lambda calculus has two simple concepts: lambda-abstraction (where a variable is declared) and application (where one lambda-term is applied to another). As has been demonstrated elsewhere, the lambda calculus is Turing-equivalent: any computable value can be expressed by a lambda expression, including such fundamental concepts as Number, numbers, arithmetic and logic In fact, pure lambda calculus only has lambda-terms and application (as everything else is derivative), but we are not so dogmatic with this module: here, a lambda-term is a prolog term (lambda/2) where the first argument is the variable declared and the second argument is its applicative use. Considered practically, the Lambda module is used to construct "functionals": anonymous functions of any arity that return a value of any type (indeed, it is possible for functionals to return other functionals). As the functional programming community has concentrated its research on program transformation, and programs in the functional style are usually lists, lambda-terms shine when assigned to list-processing tasks. In that light, the two most commonly used higher-order functions are map (that transforms a list of elements of type T0 to a list of the same cardinality with elements of type T1) and fold (that transforms ("folds") a list into some accumulated result (the easiest fold implementation is

It was introduced by Alonzo Church and Stephen Cole Kleene in the 1930s; Church used the lambda calculus in 1936 to give a negative answer to the Entscheidungsproblem.

Articles News Weblogs Buzz ... Previous The C++ Source A Deeper Look at Metafunctions by David Abrahams and Aleksey Gurtovoy August 23, 2004 Page 3 of 3 Advertisement 3.5 Lambda Details Now that you have an idea of the semantics of MPL's lambda facility, let's formalize that understanding and look at things a little more deeply. 3.5.1 Placeholders The definition of "placeholder" may surprise you: Definition A placeholder is a metafunction class of the form 3.5.1.1 Implementation The convenient names are actually typedef s for specializations of mpl::arg that simply select the N th argument for any N The implementation of placeholders looks something like this: , class A2 = void_, ... class A m , class A3 = void_, ...class A m more specializations and typedefs... Remember that invoking a metafunction class is the same as invoking its nested apply metafunction. When a placeholder in a lambda expression is evaluated, it is invoked on the expression's actual arguments, returning just one of them. The results are then substituted back into the lambda expression and the evaluation process continues. 3.5.1.2 The Unnamed Placeholder

But how can they be used together? Lambdas are anonymous functions and recursion requires names. Let's try to define a lambda that computes the nth fibonacci number. But this doesn't work. The compiler will complain about the use of fib in the lambda. Use of unassigned local variable 'fib' Eric Lippert has a great blog post on this issue. The problem is that the right hand side is evaluated before fib is definitely assigned . In this case, the compiler could potentially deduce (if the language spec allowed it) that fib is not used before it is definitely assigned, but in other cases it might need to be used before fib is assigned. A quick workaround is to assign the value null to fib and then assign the lambda to fib. This causes fib to be definitely assigned before it is used. Console.WriteLine(fib(6)); // displays 8

3 A Deeper Look at Metafunctions ISBN: url: http://www.awprofessional.com/titles/0321227255 url: http://www.boost-consulting.com/mplbook With the foundation laid so far, we're ready to explore one of the most basic uses for template metaprogramming techniques: adding static type checking to traditionally unchecked operations. We'll look at a practical example from science and engineering that can find applications in almost any numerical code. Along the way you'll learn some important new concepts and get a taste of metaprogramming at a high level using the MPL. 3.1 Dimensional Analysis The first rule of doing physical calculations on paper is that the numbers being manipulated don't stand alone: most quantities have attached dimensions , to be ignored at our peril. As computations become more complex, keeping track of dimensions is what keeps us from inadvertently assigning a mass to what should be a length or adding acceleration to velocity—it establishes a type system for numbers. Manual checking of types is tedious, and as a result, it's also error-prone. When human beings become bored, their attention wanders and they tend to make mistakes. Doesn't type checking seem like the sort of job a computer might be good at, though? If we could establish a framework of C++ types for dimensions and quantities, we might be able to catch errors in formulae before they cause serious problems in the real world.

Razonando un enigma simple El enigma de los Misioneros y los can­bales al descubierto Autor: ferdy at gentoo dot org Licencia: http://creativecommons.org/licenses/by-nc-sa/2.5/es/ Comentario inicial Hace unos d­as, como cuento un poco m¡s adelante, surgi³ la idea de implementar una soluci³n a un enigma l³gico usando un lenguaje de programaci³n. La explicaci³n de c³mo resolver el problema le gust³ a algunas personas y KarlanKas me invit³ a escribir un art­culo al respecto. A lo largo del art­culo intentar© no usar c³digo muy complicado; sin embargo en algunos casos el c³digo ayudar¡ a entender la explicaci³n. En esos casos el c³digo ser¡ en lenguaje Haskell dado que mi soluci³n la implement© usando este lenguaje. En algunos casos se requerir¡n algunos conceptos matem¡ticos. No es necesario entenderlos a fondo para seguir la explicaci³n; adem¡s en estos casos se dar¡n referencias para entenderlos y m¡s a fondo en caso de que el lector as­ lo desee. Introducci³n Hace unos d­as le­a en blackshell Juanjo propon­a un interesante reto. Se trataba de resolver el enigma de

ATOM FEED Tuesday, October 23, 2007 C++ boost lambda internals Theoretical Background: In computer science, lambda as an abbreviation refers to lambda function in lambda calculus (http://en.wikipedia.org/wiki/Lambda_calculus). lambda calculus is a fundamental concept in theory of computability developed by Alonzo Church. It's the theoretical foundation of many functional programming languages. Informally, in lambda calculus, every expression stands for a function with a single input, called its argument; the argument of the function is in turn a function with a single argument, and the value of the function is another function with a single argument. A function is anonymously defined by a lambda expression which expresses the function's action on its argument. For instance, the "add-two" function f such that f(x) = x + 2 would be expressed in lambda calculus as λ x. x + 2 (or equivalently as λ y. y + 2; the name of the formal argument is immaterial) and the application of the function f(3) would be written as (λ x. x + 2) 3. Function application is left associative: f x y = (f x) y.

Re: Computing in finite fields: what programming langage to choose? From : "Rob Thorpe" < Date : 6 Sep 2006 11:03:02 -0700 hi, i've some work to do concerning computing in finite fields and i would like to know what programming language would fit the best. I must be able to create fields and manipulate their elements: ans = alpha^4 + alpha^7 ans = 01011 * 12012 (characteristic not always 2) Also i must be able to play with polynomials: F(X) = 01011 * X^2 + alpha^5 * X + 12121 ...and also on a higher levels: F(Z) = Sum(a:A) Product(b:B, b!=a) (G(a) * Z + H(b)) So now the question is: what programming language fits the best for these type of calculus? There are several possiblities, you could use a programming languages specifically for mathematics. AXIOM could probably do it. You could also do it using normal programming languages. Languages that support lambda calculus would be useful as another suggested. In Lisp you could create a mini-language within lisp that described finite fields and use that. This path is not simple for a beginner though.

I've got a problem reading a string from a textcontrol. My code might be a little overdone on the refreshing part, but these are my futile attempts to get correct output. If you look at the code you will find I am reading a string from the textcontrol and write it to the error-log. This is ofcourse not the intended functionality but it shows what happens. when examining the error-log It appears that the only string that is being read from the control is 'h', nothing else, nomatter what I type in..... Also the app hangs when any writing to the textcontrol is performed using SetValue or AppendText, textcontrol member functions these are. Does it have anything to do with the textcontrol being inside a boxsizer?
