Stability conjecture for random initial opinions in the Hegselmann–Krause model

At least 11 years old · documented by

Let the initial opinions x1(0),…,xN(0)x_1(0),\dots,x_N(0) be chosen independently and uniformly from [0,L][0,L], and let qL,Nq_{L,N} 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 LL, qL,N→1q_{L,N}\to 1 as N→∞N\to\infty. 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.
