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

reason that miniKanren could use more search strategies than just DFS i. In many applications, there does not exist one order that serves all purposes. For example, a relational dependent type checker contains clauses for constructors that build data and clauses for eliminators that use data. When the type checker is generating

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. David Nolen's popular core.logic library is based on miniKanren, a relational (logic) language embedded in Scheme. Two of the designers of miniKanren, Willia staged-miniKanren. This project explores multi-stage logic programming in miniKanren.

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? The miniKanren implementation uses higher-order syntax (to avoid copy_term) and an advanced evaluator that removes the need for explicit iterative deepening. examples/zebra.scm The classic Zebra puzzle 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 program-ming system called miniKanren.

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.

It’s not that it’s impossible to do these things in Prolog, but it is awkward, and far from the default behavior. We encountered still different issue in extending Kanrens with constraints. miniKanren [12] is a pure logic language implemented as a purely functional, shallow embedding in its host language, here Racket [8]. microKanren is our approach to demystifying some of the complexities of miniKanren implementations.

language miniKanren as a set of combinators and syntax extension for OCaml. a number of appealing examples, confirming this observation: a type checker 

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. what miniKanren really means by "condo", the miniKanren specific if-then-else. The plan is rather the following: - Current miniKanren approach, last time I look at their book, there was a pletora of predicates defined like (= X Y), (< X Y) and (> X Y). Intention to use with "condo"?

Additional Key Words and Phrases: miniKanren, microKanren, logic programming, relational programming, Scheme, Racket, program synthesis 1 INTRODUCTION While miniKanren has been applied successfully to at least seven different programming problems [1], under-standing how miniKanren arrives at answers is challenging for all but the simplest examples.

local MK = require (" mk ") local run = MK. run: local run_all = MK. run_all: local eq = MK. eq: local not_eq = MK. not_eq: 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 This demonstration barely even scratches the surface of what’s possible using miniKanren and relational programming for graph manipulation and symbolic statistical model optimization. As the symbolic-pymc project advances, we’ll cover examples in which miniKanren’s more distinct offerings are demonstrated. Single-spaced version of my dissertation, 'Relational Programming in miniKanren: Techniques, Applications, and Implementations' - miniKanren/dissertation-single-spaced 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.

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. Unlike a function, a miniKanren relation makes no distinction between its inputs and outputs, leading to a variety of fascinating behaviors. For example, an interpreter written as a relation can also perform code synthesis, symbolic execution, and many other tasks. icfp2017-minikanren.

6 Apr 2015 Sample reports Reports show observations and matched indicators and their data. Minikanren programs often use q to represent the query.

Representing Knowledge. kanren stores data as facts that state 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: # Minikanren is a relation and logic programming language similar in many respects to prolog.
