Solving SAT via interaction net superpositions

I've recently been amazed, if not mind-blown, by how a very simple, "one-line" SAT solver on Interaction Nets can outperform brute-force by orders of magnitude by exploiting "superposed booleans" and optimal evaluation of λ-expressions. In this brief note, I'll provide some background for you to understand how this works, and then I'll present a simple code you can run in your own computer to observe and replicate this effect. Note this is a new observation, so I know little about how this algorithm behaves asymptotically, but I find it quite

Welcome to imaginary book club! I hope everyone finished the reading this week. No? Fine, we'll just wing it. At least there's snacks.

There is a deck of cards. Each has a question on it. Play starts with a random player and proceeds in a circle, with each player drawing a card and answering the question. The first two are always:

• What is the book's title?
• What is the book's genre?
