kan du använda detta tillägg https://github.com/niitsuma/Racket-miniKanren/tree/recursive som denna förlängning, möjliggör också rekursiv relation i clojure  miniKanren has been implemented in a growing number of host languages, including Scheme, Racket, Clojure, Haskell, Python, JavaScript, Scala, Ruby, OCaml, and PHP, among many other languages. miniKanren is designed to be easily modified and extended; extensions include Constraint Logic Programming, miniKanren is a family of programming languages for relational programming. As relations are bidirectional, if miniKanren is given an expression and a desired output, miniKanren can run the expression "backward", finding all possible inputs to the expression that produce the desired output. At its heart is an original implementation of miniKanren as described in William Byrd's dissertation Relational Programming in miniKanren: Techniques, Applications, and Implementations as well as the extensions described in cKanren and αKanren. It is designed to be easily extended to forms of logic programming beyond the ones provided. There is no not operator in minikanren, but you can achieve something similar with conda: (defmacro not "fail if the given goal succeeds, use with extreme caution" [goal] ` (conda [~goal fail] [succeed])) See my similar question on Google Groups javascript java clojure immutable sql clojurescript reactjs minikanren datalog xmonad cps fullstack datomic Updated Aug 20, 2017 program-in-chinese / flo Ever since I saw William Byrd and Dan Friedman present on miniKanren at Clojure/conj a few years ago, I’ve been distantly interested in the topic of logic programming. .

But miniKanren has no integer numbers, so what could be done? tarai(X, Y, Z, R) : This is an awesome question, and I think a great example to have around. It's supported but maybe not so neatly and straightforwardly as you're used to. We can describe a facts db, on a relation-by-relation basis, in the same style that you'd expect to write a recursive Kanren relation. Clojure has been doing some growing up since then, and I really wanted to attend last year’s Clojure/Conj, but wasn’t able to. Almost all of my conversations at the conference involved the questions, “Why are you at Clojure/Conj” and “How did you get interested in Clojure”. The recent language Kanren is an embedded logic programming environment in Scheme.

The more mathematical interpretation would be "conso is true for any three values a, b, c such that c is a list of at least one element, a is the first element of c … 2020-07-21 2020-06-12 MiniKanren is one such library that is available in languages like Haskell and Clojure. 7. You don’t need to use Haskell, Agda or Idris to take advantage of advanced type theory in your everyday job.

It’s easy to say that a logic variable must be a specific number: (== v 42). If you want to express that a logic variable must not be a specific number, but can still be anything else, then you’re out of luck. This capability enables an interesting kind of test-driven development with partially-instantiated programs. Synthesis is performed using a relational interpreter written in the EDSL miniKanren, which will be familiar to users of Clojure’s `core.logic`. This is a literate Clojure implementation of miniKanren, a logic programming system which can be embedded in functional programming languages. It's meant to be an introduction to the inner workings of miniKanren and of core.logic, helping you to understand more completely what's happening when you use those systems. An implementation of the mini-kanren programming language in Clojure - jduey/mini-kanren An implementation of the mini-kanren programming language in Clojure - jduey/mini-kanren The most popular miniKanren implementation is 'core.logic' in Clojure, which now has many Prolog-like extensions and a number of optimizations.

The name kanren comes from a Japanese word (関連) meaning "relation". See also. Logic programming; Tree traversal a is true if b is true and c is not (Prolog uses negation as failure, i.e. not (c) is considered proven if c can not be proven) Prolog's not also works with non-ground expressions, e.g.
