Does this mean that the "faster-minikanren" package does not provide the right definition of minikanren? 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].

Alternativt kan du överväga att bädda in miniKANREN i din kod, det är ett för en enklare matchning kan du använda Rackets mönstermatchningsmöjligheter. Odens första kompilator skriven i Racket medan dess typinferenser utvecklades med MiniKanren, ett relationellt programmeringsspråk inbäddat i Scheme. Racket. Racket, som en fullständig dialekt av Lisp, har en aggressivt enkel syntax. miniKanren betonar ren (klipp inte tillåten) logisk programmering. Denna 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].
