Synthesizing programs using example input/outputs is a classic problem in artificial intelligence. We present a method for solving Programming By Example (PBE) problems by using a neural model to guide the search of a constraint logic programming system called miniKanren. Crucially, the neural model uses miniKanren's internal representation as input; miniKanren represents a PBE problem as

20 Feb 2013 It's apparently an implementation of miniKanren in I like the metaphor he uses in that post; he also has some great examples, and he

You may also see sheet examples in DOC. 3. 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. 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.

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. 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 … package: minikanren. An embedding of logic programming in Scheme. The miniKanren language in this package is the language presented in Byrd and Friedman’s "From variadic functions to variadic relations" [1]; it is a descendant of the language presented in Friedman, Byrd… 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]] This demonstration barely even scratches the surface of what’s possible using miniKanren and relational programming for graph manipulation and symbolic statistical model optimization.

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.

Minikanren is a relation and logic programming language similar in many respects to prolog. 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.

Examples: Set of equations, Tree Disequality, N-Queens Details will be discussed during the first meeting. miniKanren Code. In order to start running miniKanren examples in DrRacket put the following implementation Tutorial: Write a Relational Scheme Interpreter in miniKanren state of relational programming through a series of examples, and explore the advancements Below is an example of a sample constraint microKanren programs using these new forms of constraints. We can still provide miniKanren syntax to the language William E. Byrd, Eric Holk, and Daniel P. Friedman.

GitHub Gist: instantly share code, notes, and snippets. 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. Simi-larly, (run5 (q) body) and (run∗ (q) body) are entered as (run 5 (q) body) and (run #f (q) body), respectively. 2.1 Introduction to miniKanren This demonstration barely even scratches the surface of what’s possible using miniKanren and relational programming for graph manipulation and symbolic statistical model optimization.

Thus, when it is run, this goal produces a result set with a single value: 3. As the other examples show, a logic variable can be unified with a wide variety of JavaScript values. What about the following example?

We present a method for solving Programming by Example (PBE) problems that miniKanren's constraints select portions of the input/output examples relevant 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 14 Dec 2015 In this post, we'll extend our last example to produce some real values The original miniKanren implementation only provides the ability to For typical data entry and storage, data usually appear in flat tables, meaning that they consist of only columns and rows, as in the following example showing no test suites but simple and nice examples written in the defined language. [ WB09], William E. Byrd, Relational Programming in miniKanren: Techniques, solving Programming By Example (PBE) problems by using a neural model to guide the search of a constraint logic programming system called miniKanren. A miniKanren-family relational logic programming language embedded in Rust. can have any number of tree-term parameters, for example: foo(, 25 Jan 2021 Relational Programming in miniKanren give examples of interesting relational programs in the miniKanren language, and show how this very Defining a central processing unit relationally using miniKanren is proposed as a new An early prototype is presented, with some sample synthesis tasks and On top of that core, it then constructs miniKanren—a full-featured relational An example with lists Our ultimate goal is to write an interpreter for miniKanren.

For example, a relational dependent type checker contains clauses for constructors that build data and clauses for eliminators that use data.

These examples demonstrate miniKanren’s potential and versatility as a platform or substrate for experimenting on executable program specifications. As with quines, these examples are themselves interesting from a theoretical perspective, may also suggest other, more practical future applications.

This is great, but, mk.scm only contains an implementation of miniKanren. You can’t input examples as you seem them in the book - this isn’t part of core Scheme. Interleaving search uses more memory than depth-first search, but can find answers in some cases in which depth-first search will diverge/loop forever. miniKanren does support a few extra-logical operators---conda, condu, and project, for example. conda and condu can be used to simulate Prolog's cut, and project can be used to get the value associated with a logic variable. 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.
