The Strong 2R-Conjecture for Hegselmann–Krause cluster locations
The Strong 2R-Conjecture for Hegselmann–Krause cluster locations
For each , let be a simple stationary renewal process on satisfying the functional strong law of large numbers, and let denote the Hegselmann–Krause evolution, with . Let be the number of points in the -th limiting cluster. Strong 2R-Conjecture. The joint locations of the clusters of should be distributed as , where , and the cluster sizes should satisfy
The source presents this as a stronger, simulation-supported refinement of the weak 2R result: the expected gap converges to , whereas this conjecture predicts a stationary lattice of cluster locations and normalized cluster sizes converging jointly to .
