I started studying miniKanren with the book "The Reasoned Schemer - second edition" and the DrRacket scheme environment. I installed the "faster-minikanren" package, but the first examples of the

no test suites but simple and nice examples written in the defined language. [ WB09], William E. Byrd, Relational Programming in miniKanren: Techniques, 

Core miniKanren. Core miniKanren extends Scheme with three operations: ==, fresh, and conde. There is also run, which serves as an interface between Scheme and miniKanren, and whose value is a list. == unifies two terms. An example of miniKanren code is evalo, a relational goal that relates expressions to the values that they evaluate to.

Nov 18, 2015 miniKanren is an embedded constraint logic programming language For example, an interpreter written as a relation can also perform code  Jan 14, 2013 This post contains some introductory examples. Informative Examples The design of LogPy is based off of miniKanren , a simple and  hosts more advanced Python implementations of unification and miniKanren Complete R and Stan Horseshoe and Horseshoe+ shrinkage prior examples  In this paper we provide an overview of mediKanren, give examples of queries in low-level and medium-level query languages, and give an example of how query   A miniKanren-family relational logic programming language embedded in Rust. can have any number of tree-term parameters, for example: foo(,  Details will be discussed during the first meeting. miniKanren Code.

miniKanren Code. In order to start running miniKanren examples in DrRacket put the following implementation file into a directory: implementation.rkt; Create a file myFile.rkt in the same directory and start with the following incantation: #

I installed the "faster-minikanren" package, but the first examples of the This demonstration barely even scratches the surface of what’s possible using miniKanren and relational programming for graph manipulation and symbolic statistical model optimization.

2009-03-10 · Many tutorials below are specifically miniKANREN tutorials. Incidentally, miniKANREN is quite efficient. mini/mk.scm The complete implementation (used in the book). mini/mkextraforms.scm Extra forms appearing in the framenotes of the book. mini/mkprelude.scm Useful definitions from the book. mini/mktests.scm All the examples used in the book.

Racket [10]. microKanren [13] is an approach to clarifying miniKanren’s complexities.

example pluso, which is entered as pluso. miniKanren’s relational operators do not follow this convention: ≡ (en-tered as ==), conde (entered as conde), and fresh.

I also looked at the other implementation minikanren-ocaml, which is also unfortunately not  Feb 2, 2019 A tutorial to logic programming using miniKanren and core.logic by For the first example (l/== [tam] ["Darmok and Jalad at Tanagra. After motivating some choices by studying the prototypical example of running Does anyone know of an application of miniKanren to model  several examples, searching for a suitable generalization of the problem under such as mini-kanren (from The Reasoned Schemer [19]) to unify the  clauses—should be taken as an example of logic programming.

A slightly more complicated example is a disequality constraint between two lists. (run* (q) (fresh (p r) (=/= ' (1 2) ` (,p,r)) (== ` (,p,r) q))) The answer states that p and r are unbound, and that p cannot be associated with 1 while r is associated with 2.

Incidentally, miniKANREN is quite efficient. mini/mk.scm The complete implementation (used in the book). mini/mkextraforms.scm Extra forms appearing in the framenotes of the book. mini/mkprelude.scm Useful definitions from the book. mini/mktests.scm All the examples used in the book. Here is an example: const { run , eq , exist } = require ( ' ramo ' ); run ()( q => exist (( x , y ) => [ eq (x, ' one ' ), eq (y, false ), eq (q, [x, y]) ])); // => [['one', false]] miniKanren can then be implemented on top of this microKanren core. Porting microKanren or miniKanren to a new host language has become a standard exercise for programmers learning miniKanren.

Mar 15, 2019 the examples a little bit too complex for my taste. I also looked at the other implementation minikanren-ocaml, which is also unfortunately not 

Jan 17, 2013 David Nolen's popular core.logic library is based on miniKanren, a relational ( logic) language embedded in Scheme. Two of the designers of  (pure constraint logic programming) languages: miniKanren, microKanren, Source code of implementations, examples, benchmarks, and formal proofs are  Sep 7, 2020 Minikanren is a relation and logic programming language similar in many http:// io.livecode.ch/ online interactive minikanren examples. Sample applications; miniKANREN; Documentation and tutorials; Availability for explicit iterative deepening. examples/zebra.scm: The classic Zebra puzzle  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  Details will be discussed during the first meeting.

It separates the core implementation from the surface syntax, and is just over 50 lines of code in length. miniKanren Code. In order to start running miniKanren examples in DrRacket put the following implementation file into a directory: implementation.rkt; Create a file myFile.rkt in the same directory and start with the following incantation: # 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. 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.
