We study large networks of parametric oscillators as heuristic solvers random Ising models. In these networks, known coherent machines, the model to be solved is encoded in coupling between oscillators, and a solution offered by steady state network. This approach relies on assumption that mode competition steers network ground-state model. By considering broad family frustrated models, we show...

The dynamics of two non-linearly coupled ring oscillators are examined in this study. Each oscillator consists three-stage inverters, through a resistor and diode. system is mathematically modeled by non-linear differential equations. A numerical phase plane, bifurcation, quantitative measures, like the Lyapunov exponent, confirm transition from periodic to chaotic oscillation broad parameter z...
