An example of miniKanren code is evalo, a relational goal that relates expressions to the values that they evaluate to. When evalo is called in miniKanren like so: (evalo q q) , it will generate quines , that is, expressions q that when run will evaluate to themselves.

Jan 14, 2013 This post contains some introductory examples. Informative Examples The design of LogPy is based off of miniKanren , a simple and

microKanren [13] is an approach to clarifying miniKanren’s complexities. It separates the core implementation from the surface syntax, and is just over 50 lines of code in length. A video I watched recently on logic programming, A Vision for Relational Programming in miniKanren, by William Byrd gives some interesting examples of relational programming using miniKanren. miniKanren is an embedded constraint logic programming language designed for writing programs as relations , rather than as functions or procedures. Call for Papers. The miniKanren and Relational Programming Workshop is a new workshop for the miniKanren family of relational (pure constraint logic programming) languages: miniKanren, microKanren, core.logic, OCanren, Guanxi, etc. The workshop solicits papers and talks on the design, implementation, and application of miniKanren-like languages.

2018), and. Jun 13, 2019 But it captures the essence of miniKanren, so it's a really fun thing to For example, if you want to have the sum of something, the relational Apr 6, 2015 Sample reports Reports show observations and matched indicators and their data. Minikanren programs often use q to represent the query. language miniKanren as a set of combinators and syntax extension for OCaml. a number of appealing examples, confirming this observation: a type checker Jun 20, 2017 The next language, miniKanren, is particularly radical and for me it was the most For example, languages are strongly typed, weakly typed, Sep 14, 2015 An example of unstructured programming is assembly language: programs consist of μKanren is part of the miniKanren family of languages.

It’s designed to be lightweight and embeddable in other host languages. There is a paper about a minimal implementation call MicroKanren that has spawned many derivatives. Minikanren is a relation and logic programming language similar in many respects to prolog.

In miniKanren queries, data ﬂow is not directionally biased: any input to a relation can be unknown. For example, a query (RX y) where yis known and X is an unknown, called a logic variable, ﬁnds values X where X and yare related by R. In other words, given Rand fdeﬁned as before, the query ﬁnds inputs X to fsuch that (fX) = y.

2015-12-07 · 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. Recently, my interest has intensified, so I picked up a copy of The Reasoned Schemer and have been working through it. We provide the database as a set of miniKanren relations.

The appendohexample is simple and has a linear search space. Even so, we hope that this example convinces you that a miniKanren stepper can be a useful debugging tool. In particular, being able to choose which disjuncts to explore is even more helpful for complex miniKanren programs with many disjuncts. Only some of the disjuncts miniKanren is a pure logic language implemented as a purely functional, shallow embedding in a host language, e.g. Racket [10]. microKanren [13] is an approach to clarifying miniKanren’s complexities. It separates the core implementation from the surface syntax, and is just over 50 lines of code in length.

The Distributive Property of Addition An example of miniKanren code is evalo, a relational goal that relates expressions to the values that they evaluate to. When evalo is called in miniKanren like so: (evalo q q) , it will generate quines , that is, expressions q that when run will evaluate to themselves.

I have been playing around with miniKanren, trying to understand it by converting very basic Prolog tutorials into it. I use Python habitually so I started with the LogPy library, which has since been forked and improved upon as a lib actually called miniKanren.

Although, you can use minikanren in such an application, you are missing out on a lot of its power if you do that. An example where such systems shine is program generation, theorem proving, knowledge databases, program verification and other applications where the search space is huge but the rules are relatively simple. Request PDF | miniKanren, live and untagged: quine generation via relational interpreters (programming pearl) | We present relational interpreters for several subsets of Scheme, written in the Keywords miniKanren,relationalprogramming,logicpro-gramming, Scheme 1. Introduction miniKanren is the principal member of an eponymous fam-ily of relational (logic) programming languages. Many of its critical design decisions are a reaction to those of Prolog and other well-known 5th-generation languages.
