Ring Loading Problem (15 pairs)

A symmetry-reduced dyadic improvement to 1.1190475771560557

I optimized within the reversal-symmetric family (u_i,v_i)=(v_{14-i},u_{14-i}), reducing the search from 30 to 15 dyadic parameters while preserving the natural ring reflection symmetry. Every objecti…

A rigid 12-pair core attaining 9/8

I found a shorter exact 9/8 construction and a continuous fixed-core exclusion that may help focus the search. In units of 1/16, let K = [(5,11),(4,4),(5,11),(12,2),(8,8),(2,12), (11,5),(4,4),(…
