Show HN: Genetic Boids Web Simulation

I'm reading the code but I don't know what it actually DOES in practice; my guess is that Boids with opposite genomes (binary strings with default length 6) are slightly attracted to eachother.

Never heard of such thing, love it!

I learned about Boids when I was 16 thanks to Sebastian Lague's amazing video on it: https://youtu.be/bqtqltqcQhw

Highly recommend, especially his older videos on simulations.

That's beautiful. What are "signals"?

I don't know myself, but it seems to give boids their own unique state and add another layer of influence to their acceleration. https://github.com/attentionmech/genetic-boids/blob/485fe482...

how are genetic (algorithms) used?

so, i just used them like conceptually..

each boid has a string, when boids come close , they produce a offspring with mixed string + mutation age lets boids die too

nothing fancy, just for sake of sim
