Exploratory Environments for Functional Programming. Describes Drusilla, a language based on relations rather than functions, and an implementation of it that infers suitable representions of relations.
It is the basis of functional programming, which after a long infancy is entering adulthood as a practical alternative to traditional ad-hoc imperative programming languages. Second, the presence of side effects, exceptions etc.
In other words, what it means to provide an argument to a function. A combinator is simply a lambda expression with no unbound variables. Points out the dichotomy between guaranteeing single-use linearity and yet hoping for term-sharing laziness. The idea behind the Church numerals is very general and allows any data type — pairs, lists, trees and so on — to be represented in a purely functional way.
The essential rule of substitution, called beta reduction, tells us how to supply a value for a function parameter and substitute all occurences of that parameter in the expression body for the provided value. There follows a wonderful section on functional programming, contrasted with imperative programming: It is also possible to represent codata, such as infinite lists, infinitary trees and so on.
Transformation and analysis of functional programs. We also looked at extensions and generalisations of functional programming, foreign language interfacing, parallelisation, and benchmarking of data structures. There are many other good passages within the paper which we do not have space here to enumerate.
Functional programming languages offer a radical alternative — they are descriptive rather than imperative, have no assignment command and no explicit flow of control — sub-computations are ordered only partially, by Functional programming thesis dependency.
Expressive power of declarative programming languages. I leave you with an extended quotation from the conclusions: The disadvantages of functional programming within a language that includes imperative features are two.
Their basic action is the assignment command, which changes the content of a location in memory and they have an explicit flow of control by which these state changes are ordered.
The Reduceron exploits wide, parallel memories and other custom architectural features to increase evaluation speed, and is prototyped in programmable hardware using a field-programmable gate array. Famous combinators are named by single letters. Furthermore, Lazy SmallCheck tests properties on partially-defined values, using the results to prune test spaces automatically.
We also did some work on partial evaluation and lazy specialisation. Lazy functional components for graphical user interfaces. Each datum is encoded as a function that captures its elimination operation, that is the way in which information is extracted from it during computation.
Presents a new way to define and compare the space usage of different program evaluation strategies. But instead of using a sample of randomly generated values they test properties for all values up to some limiting depth, progressively increasing this limit.
The design and implementation of a relational programming system. Both the thesis and the lambda calculus have been of seminal influence on the development of Computing Science. Property-based Testing and Properties as Types: The lambda calculus has three productions: Data model refinement, generic profiling and functional programming.
Now comes an important point about what happens when you try to add functional support to imperative languages, echoed by Erik Meijer recently The Curse of the Excluded Middlethemorningpaper no.
Applications of functional languages The FLARE project involved applying functional langauges to real programming tasks.Functional Programming (FP) sup BAC87 is an alternative to conventional imperative programming languages.
This thesis describes an FP interpreter implementation. Superficially, FP appears to be a simple, but very inefficient language. Its simplicity, however, allows it to be interpreted quickly. Church’s Thesis and Functional Programming – Turner One of a collection of papers celebrating the 70th anniversary of Church’s thesis inas recently recommended by Erik Meijer on twitter.

or Haskell. This thesis addresses this imbalance by speciﬁcally considering the design and analysis of functional data structures. Functional vs.
Imperative Data Structures The methodological beneﬁts of functional languages are well known [Bac78, Hug89, HJ94], but still the vast majority of programs are written in imperative languages such .Download
