Realizing oscillator based Ising machines without second harmonic injection. (a) Schematic; and (b) time domain output of the proposed EAO. A magnified image of a single oscillation period revealing the two time constants in the relaxation dynamics is also shown. (c) Schematic of the input graph (same as in Fig. 1) and the corresponding experimentally measured time domain output of the equivalent coupled EAO circuit showing the observed phase bipartition. (d) Phase plot; and (e) Corresponding sets (S1, S2) created by the (Max-) Cut; (f) 2D bar plot of MaxCut solutions measured over 10 runs using network of EAOs, and the conventional oscillators (under second harmonic injection).
