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.

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. 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. 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.

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 In which, the answer will be: Zero.

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]]

Porting microKanren or miniKanren to a new host language has become a standard exercise for programmers learning miniKanren. As a result, most popular high-level languages have at least one miniKanren or microKanren implementation.

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.

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 impressively short. http://webyrd.net/scheme-2013/papers/HemannMuKanren2013.pdf. I started studying miniKanren with the book "The Reasoned Schemer - second edition" and the DrRacket scheme environment.

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.
