 Figure 1  shows the changes in agent opinions over time in single runs with thresholds ε set at 0.01, 0.15, and 0.25 respectively. With a threshold of 0.01, individuals remain isolated in a large number of small local groups. With a threshold of 0.15, the agents form two permanent groups. With a threshold of 0.25, the groups fuse into a single consensus opinion. These are typical representative cases, and runs vary slightly. As might be expected, all results depend on both the number of individual agents and their initial random locations across the opinion space.
