Might be a dumb thing to post on hacker news, but I tried using the word boid or boids in Scrabble and my competitive wife wouldn't let me because it wasn't in the dictionary. It fit so well too!
Long before the flocking model, “boid” referred to snakes of the Boidae family, like boas and anacondas.
StarCraft 2 used boids, and I'm using boids to rewrite Age of Empires II: github.com/glouw/openempires

I've confirmed with Craig Reynolds that yes indeed, then name of Boids was inspired by The Producers: https://www.youtube.com/watch?v=aL6mTMShVyk >"He's up on the roof with his boids. He keeps boids. Doity, disgusting, filthy, lice ridden boids." -The Concierge, not a Madam
Could that be used to simulate the pandemic?

I had no idea! I would have guessed it was a contraction of "bird-oid", or something like that.

>Boids is an artificial life program, developed by Craig Reynolds in 1986, which simulates the flocking behaviour of birds. His paper on this topic was published in 1987 in the proceedings of the ACM SIGGRAPH conference. The name "boid" corresponds to a shortened version of "bird-oid object", which refers to a bird-like object. Incidentally, "boid" is also a New York Metropolitan dialect pronunciation for "bird".

#3Blue1Brown has decent (simple) SIR epidemic simulation https://youtu.be/gxAaO2rsdIs
Yesterday I got 0.5 million boids simulating in Unreal Engine at 45 fps on a GTX 1080 [0]. The bottle neck is rendering so many instanced cone meshes, the simulation without rendering can do 1 million boids at 120 fps. I'm borrowing a common data structure used in GPU fluid simulations, the dynamic hashed grid, to calculate the neighbourhood of each boid (cool tutorial here with full source code [1]). We need the neighbourhoods to calculate their urges. My code is a mess at the moment, but if there is interest I can post it to GitHub (Unity and Unreal).
Boids are an example of agent-based modelling and swarm systems. I used agent-based modelling in my PhD thesis to construct and simulate realtime, interactive 3D biomolecular models of mitochondria and neuromuscular synapses [2,3]. Now that I'm free (graduated), I'm building an iPad app to teach and communicate structural and molecular biology with immersive, and realtime simulations. Our vision is to make molecular and structural biology immersive and fun. It's not a textbook, it's a little more like Neil Stephenson's young lady's illustrated primer! :D

I’ve often pondered the feasibility of using boids (or a boid like rule system) to implement ancient combat formations like pike squares skirmish lines. Is that what you’re doing?
