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.

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).

We solve each challenge by using an interpreter for a subset of Racket, or for a slight variant of Racket.
