Building a simple oscillator based Ising machine for research and education

The modules they use seem to be fairly standard stuff, like the digital potentiometers, analog summing circuits and such.

If they already got the modules then no need to invent new PCBs just for some early-stage research.

Not so sure. I did not find the eurorack module they reference there, even on the analogue computer's manufacturer website.

It's kinda the other way around. They're using oscillators as a means to an end, ie solving physics and math problems based on the Ising model[1].

While the Ising model was created as a model of ferromagnetism, and is deceptively simple at first glance, it's turned out to be quite versatile[2] and can be used to tackle many different problems[3]. However computing solutions can take quite a lot of computing power, and this analog solution supposedly can potentially do it faster.

Yeah but you can’t adjust coupling constants so it’s not as generically useful.
