Building a simple oscillator based Ising machine for research and education
- photonthug 2y agoPretty cool, but tbh per the author/equipment list this paper is basically an advertisement.
- rebanevapustus 2y agoNot so sure. I did not find the eurorack module they reference there, even on the analogue computer's manufacturer website.
- magicalhippo 2y agoThe 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.
- daghamm 2y agoThere are many types of ring oscillators with quite different characteristics, such as temperature stability and resistance to interference. I was hoping this would be a development board with multiple types of oscillators but this doesn't seem to be the case?
- magicalhippo 2y agoIt'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.

The cellular Ising model
- akomtu 2y agoA water machine is solving the water equation in real time?
- gqcwwjtg 2y agoYeah but you can’t adjust coupling constants so it’s not as generically useful.
