IIRC this was also tried at NASA, they used some "classic" genetic algorithm to create the "perfect" antenna for some applications, and it looked unlike anything previously designed by engineers, but it outperformed the "normal" shapes. Cool to see deep learning applied to chip design as well.
- Frenchgeek 2y agoWasn't there an GA FPGA design to distinguish two tones that was so weird and specific not only did it use capacitance for part on its work but literally couldn't work on another chip of the same model?

- isoprophlex 2y agoYes, indeed, although the exact reference escapes me for the moment. What I found absolutely amazing when reading about this, is that this is exactly how I always imagined things in nature evolving. Biology is mostly just messy physics where everything happens at the same time across many levels of time and space, and a complex system that has evolved naturally appears to always contain these super weird specific cross-functional hacks that somehow end up working super well towards some goal

- actionfromafar 2y agoI think it was that or a similar test where it would not even run on another part, just the single part it was evolved on.
- hinkley 2y agoAs I recall it didn’t even work from day to day due to variance in the power supply triggered by variance in the power grid. They had to redo the experiment on simulated chips.

- noisy_boy 2y agoMy theory is that if aliens ever turn up in a ship, assuming it is visible, it will be a butt-ugly super optimized messy asymmetrical shape.
