The latter is guaranteed by the strong confluence property of reduction in this model of computation. Thus interaction nets provide a natural language for massive parallelism. Interaction nets are at the heart of many implementations of the lambda calculus, such as efficient closed reduction [2] and optimal, in Lévy's sense, Lambdascope. [3]
In some ways, the history of programming language theory predates even the development of programming languages themselves. The lambda calculus, developed by Alonzo Church and Stephen Cole Kleene in the 1930s, is considered by some to be the world's first programming language, even though it was intended to model computation rather than being a means for programmers to describe algorithms to a ...
The DNA passes through the mannose permease complex in the inner membrane [10] [11] (encoded by the manXYZ genes) and immediately circularises using the cos sites, 12-base G-C-rich cohesive "sticky ends". The single-strand viral DNA ends are ligated by host DNA ligase. It is not generally appreciated that the 12 bp lambda cohesive ends were the ...
In combinatory logic for computer science, a fixed-point combinator (or fixpoint combinator), [1]: p.26 is a higher-order function (i.e. a function which takes a function as argument) that returns some fixed point (a value that is mapped to itself) of its argument function, if one exists.
Brian Kernighan, co-designer of AWK and AMPL, co-author of "The C Programming Language", promoter and designer of "little languages": Eqn, Pic, Grap; Gregor Kiczales, the 2012 AITO Dahl–Nygaard Prize, for his work on CLOS and the MOP and for spearheading aspect-orientation and AspectJ
Scheme is a dialect of the Lisp family of programming languages.Scheme was created during the 1970s at the MIT Computer Science and Artificial Intelligence Laboratory (MIT CSAIL) and released by its developers, Guy L. Steele and Gerald Jay Sussman, via a series of memos now known as the Lambda Papers.
In computer science, Programming Computable Functions (PCF) is a typed functional language introduced by Gordon Plotkin in 1977, [1] based on previous unpublished material by Dana Scott. [note 1] It can be considered to be an extended version of the typed lambda calculus or a simplified version of modern typed functional languages such as ML or ...
[6] [7] The below summarises the language presented in the 2007 paper. [2] Janus is a structured imperative programming language that operates on a global store without heap allocation and does not support dynamic data structures. As a reversible programming language, Janus performs deterministic computations in both forward and backward ...
