yes had the same idea but applied that by doing randomization in age: floor(random(0, this.lifespan))

for me its not vanishing suddenly, so not sure how to reproduce now

dies in the sense machine gets hung or all boids vanish?

EDIT: also pushed some fixes in params (allow offsprings at larger distance, etc), but basically if the boids don't end up closer, they won't reproduce and the population dies so play with that and lmk

oh nice, webGPU thing should learn sometime!

oh, so i wasn't really aware that there was a original boid sim (I will check it today). mostly I saw it on some other demos and I wanted to add this behaviour of signaling boids which are far away + color code based on genome + do a simple cross-mutate. and yes you are right about fitness func.

Beyond this i was trying to add a map which effects their movement. (if you wanna check how it looks - https://x.com/attentionmech/status/1925690991555531143)

hey thanks! color is coming from genome (check brightColorFromGenome)! nice suggestions, will definitely try to incorporate some of them.

fixed it. lowered the values and clipped.

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

why we care about biological pain so much is because we know - we ourselves feel it. everyone has felt how miserable it makes them. For AI, one way to see these experiments is at some point it will help us know or atleast have the right tools at the right time -> to discover if such empathy needs to be extended to AI systems.

So my suggestion to OP is what you are doing today will help us give these systems the right treatment someday when they will qualify for it.

For someone it might help: If you are having trouble reading long articles, try text-to-audio with line highlight. It helps a lot. It has cured my lack of attention.

with all the AI stuff going around, can't github just scan repos for such malicious code?
