I like the idea of evolving agents from scratch with no "learning", they just evolve their ability to survive in the environment. Maybe one day it'll be advanced enough to see life evolve.

How does the narrative story generator work?

I played around a bit with NEAT networks, and tried to create a bitcoin trading bot, but the best I could do was a +10% gain over many months. I was hoping for at least 30% each month. Oh well, I guess it doesn't all just depend on past price history.

I think it looks fun, but at the same time I really wish you had written the readme yourself and not using an llm. My view: if you can’t be bothered to write it yourself, why should I read it myself?

got the updated version up and again, appreciate the nudge there!

It is impossible to enforce a world free of heuristics, but this is certainly very cool. Reminds me of that Black Mirror episode with the circular QR code.

completely agree on the heuristics (someone else mentioned the MIT Koan comment about this). And yeah Plaything is a little too close to home... no QR codes from werld agents yet though. Will keep you posted.

Arguably a powerful demonstration of why even simple creatures make use of parenting as a strategy to improve the success of their offspring.

This actually showed up in the first run, agents that invest more energy into offspring vs ones that fork cheap and fast.

the ones that survived population crashes were the ones passing down leaner, better-inherited brains. Cheap forking works when there's plenty of energy around, falls apart in famine.

this reminds me of Polyworld by Larry Yaeger, an artifical life sim where each creature has a vision system. i played around with this back in the early 2000s though the hardware i had access to was basically insufficient to run it in any real way. it's nice to see its development has continued. https://en.wikipedia.org/wiki/Polyworld

Haven't come across Polyworld before — just looked it up and its super cool, especially for 1994. The vision system is a interesting design choice. Werld takes a different approach — graph topology instead of a 2D plane, and NEAT brains instead of Hebbian learning — but the core philosophy is the same.

And yeah hardware has caught up a bit since the early 2000s, though my hard drive is having a hard time. Thanks for the reference, going to dig into Yaeger's papers.

wonder if the black mirror episode was based on polyworld then?

Thanks! The story generator is pretty simple right now — every 10,000 ticks the sim snapshots population stats, brain complexity, species changes, births/deaths, communication activity and runs it through a template that writes a plain-english chapter.

Building out a more engaging version, and will hopefully stream it onto X again as a story - but this time without chewing api tokens every couple of seconds.

NEAT for trading is interesting - on BTC i used a kernels method that worked quite well and closer to that <2 sharpe on a monthly.

I just wanted to add: there’s no single piece of machinery that can void the human experience. A large collection of machinery can only delay the inevitable. Please have fun with your project.

Agreed — and I wouldn't want to simulate the human experience. What I'm more curious about is what experience agents would create for themselves, with no concept of ours.
