Contribute to miniKanren/Racket-miniKanren development by creating an account on GitHub. We solve each challenge by using an interpreter for a subset of Racket, or for a slight variant of Racket. These interpreters are written as relations in the constraint logic programming language miniKanren. Each interpreter relates two arguments: an expression expr to be evaluated, and the value val to which expr evaluates. We expose concept and edge information to a miniKanren program by defining the relationsconcepto and edgeo.

I started studying miniKanren with the book "The Reasoned Schemer - second edition" and the DrRacket scheme environment.

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, and Kiselyov’s The Reasoned Schemer [2]. The code itself was written by (in alphabetical order) Will Byrd, Dan Friedman, Oleg Kiselyov, and Racket-miniKanren.

Installation is straightforward, but there is little documentation. The package has to be obtained from GitHub instead of through the Racket Package Index. We solve each challenge by using an interpreter for a subset of Racket, or for a slight variant of Racket. These interpreters are written as relations in the constraint logic programming language miniKanren. Each interpreter relates two arguments: an expression expr to be evaluated, and the value val to which expr evaluates. MiniKanren support by Dr Racket As the readme says, you need to put (require minikanren) in your Racket source file. I've put in on the second line, after #lang racket, copied the appendo definition, #lang racket (require minikanren) (define (appendo l s out) (conde [(== l '()) (== s out)] [(fresh (a d res) (== `(,a .

Or am I making a mistake? 回答1: As the readme says, you need to put (require minikanren) in your Racket source file. I've put in on the second line, after #lang racket, copied the appendo definition, 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. It separates the core implementation from the surface syntax, and is just over 50 lines of code in length.

Includes compatibility files for Racket and various Scheme implementations. cKanren miniKanren extended with Constraint Logic Programming (CLP); an improved version of the system described in the 2011 Scheme Workshop paper. Racket-miniKanren A racket port of the version of minikanren from the artifact of the ICFP 2017 Pearl, A Unified Approach to Solving Seven Programming Problems by William E. Byrd, Michael Ballantyne, Gregory Rosenblatt, and Matthew Might. Includes evalo-optimized.

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.
