Stability conjecture for random initial opinions in the Hegselmann–Krause model
Stability conjecture for random initial opinions in the Hegselmann–Krause model
Let the initial opinions be chosen independently and uniformly from , and let be the probability that the resulting equilibrium is stable, meaning that every pair of distinct positive-weight clusters is separated by more than one. Stability conjecture. For every fixed , as . This asserts that random initial opinions almost surely produce stable equilibria in the large-population limit; the source further notes a stronger expected version for any continuous bounded density with connected support, while attributing a related result to prior work.
