refal - Refal is a language for string istighfar pendek processing language translation and artificial intelligence based on pattern matching and term rewriting It was designed in 1966 and implemented in 1968 by Valentin Turchin and others Brief Outline of REFAL A REFAL Interpreter swissChili REFAL5 history Whatever happened to the Refal language Jun 11 2021 Refal is a recursive functional algorithmic language with pattern matching and dynamic typing Learn about its history syntax features and examples from the presentation by Alexander V Konovalov a professor at Bauman Moscow State Technical University Jun 6 2020 Refal is a metaalgorithmic language for describing the conversion of symbolic information such as translating between languages or proving theorems It uses recursive functions and concretization rules to calculate the value of expressions 24 Representation of Refal expressions 25 The algorithm of pattern matching 3 BASIC PROGRAMMING TECHNIQUES 31 Brackets as pointers 32 Function formats 33 Implicit and explicit recursion 34 Duplication of variables 35 Breaking algorythms into functions 36 Recurtion and iteration 37 Dealing with nested parentheses 4 EXTENDED REFAL REFAL Recursive Functions Algorithmic Language was designed by Valentin F Turchin at the Moscow Institute of Physics and Technology in 1966 with the first implementation completed in 1968 The language was designed for artificial intelligence natural language processing and more natural construction of recursive algorithms Turchin 1989 REFAL5 Programming Guide and Reference Manual

language created by V Turchin to describe semantics of other languages It has no types uses objective expressions patterns and result expressions and has several dialects and implementations REFAL The Language for Processig XML Documents abstract REFALJAVA REFAL IT History Society GitHub swissChiliREFAL An interpreter and IDE for the Preface Рефал5λ Hereinafter the suffix λ5 will often be omitted Instead of Refal5λ it will be indicated by Refal Initially Simple Refal language was a research project and was developed by Alexander Konovalov aka Mazdaywik pronounced as Mazdaischik The author wanted to understand how the REFAL code is compiled in the imperative code Refal Wikipedia Mar 13 2014 Refal is a programming language invented by Valentin Turchin a computer scientist and philosopher to model metasystem hierarchies and metacomputation Learn the history grammar and features of Refal and how it relates to supercompilation and verification Refal for Recursive Functions Algorithmic Language is a programming language for manipulation of symbolic information We argue that toto bet sgp Refal is the best language for processing documents in XML HTLM and similar formats because it has the following unique combination of features Refal is a functional language This commit does not belong to any branch on this repository and may belong to a fork outside of the repository master Refal is a language created in Russia in the 1960s where computation is driven by matching textual and symbolic information Learn about its computation model program structure data representation and examples of functions and expressions Documentation and Training Refal REFAL is symbol objects manipulating language such as texts formulae programs etc REFALprogram consists of functions which can define each other ie in recursive mode Hence its name follows REcursive Functions Algoritmic Language Basis of programming in Refal Basic Refal Рефал5λ Refal University of Liverpool Introduction in

Hello World and use comments braces and semicolons REFAL5λ is an extension of REFAL5 a language for describing semantics of other programming languages It supports bidirectional sequences pattern matching higherorder and nested functions and C integration RefalJava is a programming language that simplifies algorithms for analysing and transforming programs It is based on Refal6 and runs on top of the Java TM 2 Platform with access to its libraries and features Refal Encyclopedia of Mathematics Oct 29 2020 Given that Valentin Turchin the author of Refal came to the U S in 1977 started working at CUNY in 1979 and Sendmail shipped in 1983 there was plenty of time for people involved in computer science to get acquainted with his ideas Someone who has Eric Allmans contacts should ask him if he had heard of Refal when he developed Sendmail Refal Dev Tools Introduction to the Refal programming language Refal mathbasbg Introduction to Refal Refal is a functional programming language for symbolic manipulation It was developed in the Soviet Union in the late 1960s by Keldysh Institute of Applied Mathematics and was extensively used for academic research and some specialized realworld applications particularly in the Russianspeaking world Refal The Refal programming language Recursive Functions Algorithmic Language is a firstorder functional language with an applicative insideout semantics Unlike LISP the language is based on the model of computation known as Markovs algorithms Roughly speaking a program in Refal is demo slot gila138 a term rewriting system
