Extended Data Fig. 1: Raw phase map data with post-processed results.
From: A 1,968-node coupled ring oscillator circuit for combinatorial optimization problem solving
Raw phase maps are shown for uniform, chequerboard, and random pattern graphs. A lightweight post-processing method that emphasizes the relative phase difference between adjacent nodes can eliminate non-ideal effects and produce the expected spin value maps on the right. The weights and spin values are colour coded and overlaid for better visualization. ROSCs are indexed from 1 (upper left corner) to 1,968 (lower right corner), with ROSC 1 being directly above ROSC 42.
