Bodil Stokke on µKanren: A Minimal Functional Core for Relational Programming
- Meetup: http://www.meetup.com/Papers-We-Love-London/events/220542230/

Relational programming, or logic programming, is a programming paradigm that exhibits remarkable and powerful properties, to the extent that its implementation seems frightfully daunting to the layman. µKanren is a minimal relational language that seeks to strip the paradigm down to its core, leaving us with a succinct, elegant and above all simple set of primitives on top of which we can rebuild even the most powerful relational constructs.
In this talk, we will explore the µKanren language by implementing it from first principles in a simple functional programming language, going on to demonstrate how you can assemble these simple building blocks into a semblance of its richer parent, miniKanren, and maybe solve a logic puzzle or two to make sure it’s working as advertised.
The µKanren paper, and the original µKanren implementation, were authored by Jason Hemann and Daniel P. Friedman. The paper is available at http://webyrd.net/scheme-2013/papers/HemannMuKanren2013.pdf, and the Scheme implementation at https://github.com/jasonhemann/microKanren.

The London Chapter would like to thank uSwitch for helping to make this meetup possible.
