Another person has posted about trouble using the Reasoned Schemer 2nd ed code in Racket, but I thought I would add some specifics: My trouble starts in Chapter 1, Frame 50, where conj2 is used. conj2 is not defined in the installed files, so I typed in the definition of conj2 and everything that it depends on, using the definitions provided in Chapter 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. Canonical miniKanren implementation in Racket . 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.

These relations are defined using miniKanren’sproject construct, which allows us to implement them with Racket code that accesses our database representation, choosing an appropriate index to use based on 1 204 8.9 Racket Proof-of-concept for reasoning over the SemMedDB knowledge base, using miniKanren + heuristics + indexing. Project mention: Bertrand Might: Life, legacy and next steps | news.ycombinator.com | 2021-01-22 Our miniKanren implementation will use constraint solving and search to fill in the logic variables with expressions and values consistent with the semantics of Racket.

staged-miniKanren. This project explores multi-stage logic programming in miniKanren. While partial evaluation has a rich history in both functional and logic programming, multi-stage programming has so far only been explored in a functional/imperative setting, with many success stories in high-performance computing.

An alternative miniKanren package is the one provided by the authors, which is the canonical implementation of miniKanren in Racket (Racket-miniKanren).

There is also run , which serves as an interface between Scheme and miniKanren miniKanren is an embedded Domain Specific Language for logic programming. Does this mean that the "faster-minikanren" package does not provide the right definition of minikanren?

For example, miniKanren can not handle Scheme code like #0 = ( #0# 3 ). Such recursions appear in many applications, e.g.

I managed to install guile, a scheme variant, and can run the miniKanren test cases successfully. I now would like to run tarai, which reads in Prolog as follows.

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.
