New methods optimize unit-distance lower-bound certificates

By PulseAugur Editorial · [3 sources] ·

Researchers have developed new computational methods to optimize lower-bound certificates for the unit-distance problem. This work builds upon the 2026 disproof of Erdős's conjecture, which showed that the number of unit distances among n planar points can exceed n^(1+epsilon). The new approach formulates parameter selection as a nonlinear integer programming problem and introduces an open-source Python pipeline for verification and improvement. The optimized certificates suggest that the maximum number of unit distances can exceed n^1.0152 for arbitrarily large n. AI
