在本文中，我们报告了一种新的伊辛机器技术的新结果，该技术用于解决使用耦合自维持振荡器网络的组合优化问题。具体来说，我们提出了几个使用CMOS电子振荡器的工作硬件原型，构建在面包板/perfboards和pcb上，实现了由多达240个旋转和可编程耦合组成的Ising机器。我们还报道，仅通过模拟更大尺寸的此类伊辛机的微分方程，就可以轻松地在基准优化问题上获得良好的解，从而证明了基于振荡器的伊辛机的有效性。
In this paper, we report new results on a novel Ising machine technology for solving combinatorial optimization problems using networks of coupled self-sustaining oscillators. Specifically, we present several working hardware prototypes using CMOS electronic oscillators, built on bread-boards/perfboards and PCBs, implementing Ising machines consisting of up to 240 spins with programmable couplings. We also report that, just by simulating the differential equations of such Ising machines of larger sizes, good solutions can be achieved easily on benchmark optimization problems, demonstrating the effectiveness of oscillator-based Ising machines.
