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

Volta Archives December 2007 (4) May 2007 (2) March 2007 (4) February 2007 (6) ... September 2005 (1) Anonymous Recursion in C# Recursion is beautiful and lambdas are the ultimate abstraction. 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
