miniKanren is a family of programming languages for relational programming. Synthesizing programs using example input/outputs is a classic problem in

For example, for all of our interesting miniKanren examples, a complete search is necessary. And we need the occur check. And we can’t use cut in many cases. And we use some special constraints. It’s not that it’s impossible to do these things in Prolog, but it is awkward, and far from the default behavior.

The core language, using Scheme as the host language, is described in this short, interactive tutorial. 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. 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.

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. Crucially, the neural model uses miniKanren’s 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. 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: # This demonstration barely even scratches the surface of what’s possible using miniKanren and relational programming for graph manipulation and symbolic statistical model optimization.

What is miniKanren? miniKanren is an embedded Domain Specific Language for logic programming.

Step 2: Get miniKanren. If you follow the download links on the miniKanren site you’ll probably end up at this Github repo. 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.

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.

miniKanren is an embedded Domain Specific Language for logic programming. If you are unfamiliar with miniKanren here is a great introduction video by Bodil Stokke: If you like that, then the book, The Reasoned Schemer , explains logical programming in miniKanren by example.

In fact, this constraints are very useful on its own, since they allow to express facts like `forall (i) (e =/= Const i)` from my first example. 2) Negated goal constructor: `~g`. It takes goal `g` and produces new goal. 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 recursive constraints imposed by the provided examples. Jan 7, 2013 In this UnConf talk, Dan Friedman and William Byrd demonstrate the miniKanren logic programming system for Scheme. Below is an example of a sample constraint microKanren programs using these new forms of constraints.

miniKanren. ML Agent program. solving Programming By Example (PBE) problems by using a neural model to guide the search of a constraint logic programming system called miniKanren. 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 Nov 18, 2015 miniKanren is an embedded constraint logic programming language For example, an interpreter written as a relation can also perform code [Implementation and examples] challenges in Racket, and an elegant, unified approach to solving them using constraint logic programming in miniKanren. 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(, May 16, 2020 If there is no solution, miniKanren can go on forever if the search tree is infinite.

2.1 Introduction to miniKanren miniKanren project syntax to write Racket code that interfaces with this representation. Performance is sufficient for the GUI to support low latency querying in the common case. In this paper we provide an overview of mediKanren, give examples of queries in low-level and medium-level query 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. miniKanren Code.

Such features usually do not compose well in the sense that they are sensitive to the order in which they appear in a program. For example, consider the goal (c →∗t ; e) ∧g, and assume that c ∧g always fails regardless of the order of conjuncts. Then if c succeeds miniKanren is an embedded Domain Specific Language for logic programming.

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

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"?
